For a 20 V rail switching at 500 kHz, the ripple current rating is roughly 1.2 A RMS — above that, the ESR losses push the core temperature past the derating curve. The -55°C to 125°C operating range covers industrial motor drives and automotive underhood electronics, but at the low end the ESR roughly doubles, so the ripple current budget shrinks. The ±20% tolerance is standard for tantalum electrolytics — this is a bulk storage cap, not a timing or filter element. At 68 µF, the actual capacitance at 20 V bias is about 20% lower than the nominal value due to DC bias derating, so the effective decoupling capacitance is closer to 54 µF. The D case is the most common footprint for this capacitance-voltage combination, meaning the PCB land pattern is widely supported across manufacturers. ## Active production — no LTB pressure For a BOM that already qualifies this cap, the supply chain risk is low — no forced redesign or end-of-life inventory hoarding.","metaTitle":"KYOCERA AVX TPSD686M020R0200 Tantalum Cap, 68 µF, 20 V","metaDescription":"KYOCERA AVX TPSD686M020R0200 molded tantalum capacitor, 68 µF, 20 V, 200 mΩ ESR, D case 2917, -55 to 125°C.

This value determines the ripple current the capacitor can handle before self-heating becomes a problem — at 20 V and 68 µF, the ripple current limit is roughly 1.2 A RMS. Higher ESR means more internal heat for the same ripple, so this cap is suited for moderate-ripple bulk decoupling, not high-frequency switching supplies where lower ESR (e.g., 100 mΩ) would be preferred."},{"question":"What temperature range does TPSD686M020R0200 cover?","answer":"This qualifies it for industrial environments and automotive underhood applications, though at the low end the ESR roughly doubles, reducing the ripple current budget. The 125°C absolute maximum includes self-heating from ripple current, so the ambient temperature plus internal temperature rise must stay under that ceiling."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSD686M020R0200","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSD686M020R0200 when reusing this data.
