KEMET manufacturer-generated specificationGenerated 26 Sep 2026 · 1: dimensions and electrical properties

Differences & datasheets
  • Manufacturer construction, terminal tolerances, and effective capacitance under bias may differ.
  • Check effective capacitance at the circuit's DC bias, temperature, and AC ripple.
  • Verify footprint, height clearance, and required voltage derating before substitution.
  • DC-bias curves, ESR/ESL, ripple heating, aging, and circuit stability have not been matched.

TDK product specificationChecked 26 Sep 2026 · Size; Electrical Characteristics; Other; Product Status

Differences & datasheets
  • Minimum insulation resistance rises from 100 MΩ to 500 MΩ; differing conditioning and package tolerances still need review.
  • Published body and termination tolerances, loss/leakage limits, measurement conditions and aging can differ; compare the fields and source documents.
  • Minimum insulation resistance rises from 100 MΩ to 500 MΩ; differing conditioning and package tolerances still need review.
  • Verify effective capacitance at the actual DC bias, AC amplitude, temperature and age. Recheck regulator stability or filter response at worst-case capacitance.
  • Confirm land pattern, maximum height, voltage margin, ripple heating and soldering profile. These comparisons cover general-purpose MLCCs; special qualification or soft-termination equivalence is not established.
  • DC-bias curves, ESR/ESL across frequency, ripple heating and aging have not been matched in the circuit.
  • Full conditioning and measurement equivalence, qualification, board-flex reliability and assembly-process compatibility remain unverified.
