The surface-mount package reflows on a standard profile; the molded body gives mechanical protection during pick-and-place and rework. ## Temperature grade and derating margin Rated -55 to 125 °C, this cap covers the full industrial temperature band and the lower end of automotive under-hood ambient. The 20 V rating at 85 °C derates to roughly 13 V at 125 °C per standard tantalum derating practice — a 50 % voltage margin below the rated voltage at the operating temperature is the usual reliability rule for tantalum, so a 12 V rail at 85 °C is comfortable, but a 12 V rail at 125 °C pushes the margin thin. For decoupling applications where the absolute value is not critical, this is fine; for timing or filter poles, the tolerance and temperature coefficient need to be budgeted into the design. ## Active lifecycle — no end-of-life signal Listed as Active with no NRND or EOL flags. This part is safe for new designs and ongoing production.","metaTitle":"KYOCERA AVX TPSD686M020R0300 Tantalum Cap, 68 µF, 20 V","metaDescription":"68 µF, 20 V molded tantalum capacitor, 300 mOhm ESR at 100 kHz, -55 to 125 °C, 2917 (7343 Metric) D case.

This ESR value determines the self-heating under ripple current and the filtering effectiveness at switching frequencies. A lower ESR means less heat and better high-frequency bypass; 300 mOhm is typical for a D-case tantalum at this capacitance and voltage rating."},{"question":"What package and case code does TPSD686M020R0300 use?","answer":"Molded 2917 (7343 Metric) surface-mount package, manufacturer size code D."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSD686M020R0300","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSD686M020R0300 when reusing this data.
