Methodology notes: The manufacturer family declares 1.2 mg per 0402 part. Known retained constituents cover 86.6666666667% of full mass; 13.3333333333% remains compositionally unassigned. Both electrode and termination nickel are included. Only known feeds are divided by 0.95 for the assumed 95% retention, with 0.0456140350877 kg/kg matching signed manufacturing-waste provision. Utilities are assumed 1 kWh electricity and 5 MJ heat per kg finished part. Unknown retained mass and its manufacturing loss are not fabricated or normalized away.
System boundary: Known material supply, assumed manufacturing utilities and known-feed fabrication-loss treatment per kg finished capacitors. Complete finished-part retirement belongs to the board/control assembly.
Included life cycle stages: Manufacturing
Technology description: The retained recipe supplies CaZrO3 ceramic, electrode/termination metals and any explicitly declared flexible-contact material through qualified commodity and ceramic-production proxies. Full finished-part mass includes the unresolved composition fraction.
Intended application: Family/case material provision within an explicitly qualified fitted-capacitor model, retaining unassigned composition and manufacturing boundaries.
Use limitations: The material declaration calls these engineering calculations, not exact product assays or measured factory LCI. Family transfer to fitted Murata/TDK and other dielectric/temperature classes does not establish electrical or chemical equivalence. Miscellaneous mass is not evidence of zero palladium or dopants. Purity, particle engineering, milling, binder burnout, cofiring/plating, water and recovery are not established; generic hazardous-waste provision is a burden proxy rather than a legal waste classification.

Source location: June 2026MCD cover/remarks andAnnexes1–3
Qualification: The recovered primary MCD is June 2026,with KEMET declarations and YAGEO copyright. The TI SLURB87 BOM was last updated October 2025. These are corporate technical documents,not journal articles or measured manufacturing LCIs. Corporate issuer names are bibliographic authorship,not newly inferred people or CLIC contributors; preserve Romain Sacchi's existing inventory authorship. No DOI or ORCID is invented.

Source reference: https://yageogroup.com/content/Resource%20Library/Material%20Declaration/MCD-Ceramic.pdf
Source location: PDF pages4,6,8 (Annexes1–3),known material and unknown fractions
Qualification: MCD Annex 1provides BaTiO3 Class2 families,Annex 2 flexible termination andAnnex 3 CaZrO3 C0G. Both electrode and termination Ni contribute to the material dose. Flex0805has declared Ag while its epoxy/other material fraction remains unresolved. Class2/X7R family transfer to Murata/TDK X7T,X7S,X8L andother exact devices is an engineering analogue,not exact product substitution or proof of electrical equivalence. MCD explicitly calls its values engineering calculations rather than exact product content. Its miscellaneous category is not a measured zero-Pd or zero-dopant assay. One kg CLIC part includes the full declared component mass with unassigned retained fractions; known materials are not renormalized to100 percent or filled with invented resin/oxide. C0G 0402unassigned fraction is13.333 percent. Preserve this uncertainty and separately reviewed legacy Pd-bearing capacitor recipes. The current95 percent reference retention increases only known material inputs and assigns the corresponding known loss to a signed generic hazardous-waste treatment. Source unassigned material manufacturing loss is not estimated. This is not measured scrap yield,class classification,actual cofiring/plating loss or complete mass coverage. Complete finished-part retirement belongs to the board/control package; do not add a second end-of-life treatment at component/set level.

Qualification: Pure BaCO3+TiO2→BaTiO3+CO2 andCaCO3+ZrO2→CaZrO3+CO2 reproduce current ideal precursor and calcination CO2 amounts. Powder utilities 3 MJ heat/.5kWh per kg andfinished-capacitor 5 MJ/1 kWh are assumptions. Actual ceramic grade,particle size,milling,binder burnout,sintering/cofiring/plating,water,recovery andfugitive emissions are not supplied by MCD. Carbonate geological/reagent carbon origin is not validated by stoichiometry alone.

Source location: October 2025fitted quantity column and current 5784
Qualification: TI's current fitted quantity column gives134 capacitors in 28 rows:51Class 2 0402,25Class 2 0603,5Class 2 0805,6Class 2 1206,1 flexible 0805,11 C0G 0402,2 C0G 0603 and33 C0G 0805. Current5784matches this corrected mix. Historical55/27/38 Class 2 plus7C0G 0402notes are superseded;39 parts were reclassified by dielectric andcase. Not-fitted rows andold case-only classifiers must not be restored. Current 134-part-set mass is.98098g under the declared family transfer. Two actual KEMETC0402C120J3GACAUTO parts retain the inherited 1.06 mg allowance; remaining 9C0G 0402parts use1.2 mg family mass. The current official part URL redirects to a generic page anddoes not verify exact 1.06 mg. A different C0402C121part or generic0402datasheet does not establish this precise mass. Preserve the assumption with an explicit sensitivity rather than claim a recovered exact datasheet. The source TIDA-020076 is an 18-cell wired/wireless supervisor reference,not the reconstructed CLIC 70 g/16channel board. Its PCB/manufacturers/part counts do not establish full fitted circuit equivalence of a different monitor. CLIC module-board capacitor sets are1/.07 per kg board; central-board 2 g Class 2 0603 andauxiliary 25 g/kg allowances are separate generic references. Do not multiply134 parts into those boards or add another populated-board proxy.

Source location: Corporate issuer,verified TI US parent and source-manufacturer roles
Qualification: KEMET Electronics Corporation declaration issuer,YAGEO Corporation publisher/parent andTexas Instruments design owner have distinct roles. The 2020 acquisition concerns KEMET Corporation becoming a YAGEO subsidiary; do not automatically merge the bylined operating entity,holding company andparent. Scoped KEMET/YAGEO ROR searches did not verify exact identifiers. TI's verified US parent is 03vsmv677; similarly named Norway/Ireland/other-country organizations are not substitutes. Murata,TDK andother BOM makers are not made KEMET subsidiaries by material-family transfer. Corporate source authorship,manufacturer ownership,document copyright andcomponent suppliers are not evidence that those organizations funded this CLIC engineering reconstruction. Preserve project/funding arrays,licences,background/biosphere profiles andpublished states. Current published archive status takes precedence over inherited candidate/preview wording. No source permission,industrial assay or full board-performance certification is inferred.

Source location: Current primary payload digests andscoped source-history searches
Qualification: Current source-family andcomponent mix quantities agree,including the earlier39part correction. The source PDF payloads exactly match earlier pinned manufacturer/BOM digests in the existing refinement script. This verifies those two cached payload identities,not a complete publisher revision history. Legacy KEMET material-document endpoints failed andthe product page was generic; no authoritative additional erratum/change notice was found in scoped searches. Crossmark status is not established for these corporate documents.

Qualification: Technical-characterisation review TC-3667. Technological representativeness: 4. Basis: The exact CLIC bill transfers manufacturer family/selected-variant material content into an engineering manufacturing model with generic process/energy and wafer assumptions. The custom assemblies also transfer fitted counts and mass proxies. This is proxy-based representation, not a source-validated circuit or factory inventory. Evidence classification: curator assessment with manufacturer route evidence. Confidence: medium curator judgement. A retained model value is not a measured observation or industrial certification.

Qualification: Technical-characterisation review TC-3667. Geographical representativeness: 3. Basis: The supplied manufacturing reference uses generic/global background supply and a manufacturer family or selected assembly variant without a global production-weighted sample. Treat it as a generic geographical proxy. A selectable assembly site is not a global average; a manufacturer headquarters address is not a fabrication location. Evidence classification: curator assessment with manufacturer route evidence. Confidence: medium curator judgement. A retained model value is not a measured observation or industrial certification.

Current vendor material/reliability declarations do not date background manufacturing energy or validate a custom circuit's deployment stage. For custom component-count assemblies, do not automatically transfer the component route's maturity/TRL. Evidence classification: explicit source scope gap.
