The 20 V rated voltage is derated per MIL-PRF-55365 guidelines — at 125°C, apply 50% derating (10 V max) for long-life reliability. For automotive under-hood use, the 125°C ceiling provides margin above the 105°C typical ambient.","metaTitle":"TAJB156K020A KYOCERA AVX Molded Tantalum Capacitor 15 µF 20","metaDescription":"TAJB156K020A KYOCERA AVX TAJ series molded tantalum capacitor, 15 µF, 20 V, ±10%, 2 Ohm ESR, -55°C to 125°C, 1411 (3528 Metric) package.

Standard reflow soldering applies; the part is supplied on tape and reel."},{"question":"Can TAJB156K020A replace TAJB156K020?","answer":"TAJB156K020 is a prior suffix variant in the same TAJ series. The 'A' suffix on TAJB156K020A typically indicates a packaging or termination finish update (e.g., RoHS compliance). Electrical ratings (15 µF, 20 V, ±10%, 2 Ohm ESR) and footprint (B case, 1411) are identical. Confirm the specific suffix definition in the KYOCERA AVX datasheet, but for most BOM positions the two are drop-in interchangeable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJB156K020A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJB156K020A when reusing this data.
