The 100 mOhm ESR at 100 kHz sets the ripple-current ceiling and the self-heating under AC load — a lower ESR means less internal temperature rise for the same ripple, which matters in a power-supply output filter where the cap sees the switching ripple directly. ## Temperature range and operating environment The 125°C upper limit means it can sit near a hot MOSFET or regulator without derating — but tantalum capacitors lose capacitance and increase leakage at the high end, so the actual ripple current at 125°C must be checked against the voltage-derating curve for the series. ## Package and footprint — 2917 case D The standard tantalum footprint uses a 2.8 mm pad spacing with adequate thermal relief to the cathode pad — the molded body is moisture-sensitive, so bake before reflow if the shelf-life window is exceeded.","metaTitle":"KYOCERA AVX TPSD687K004R0100 Tantalum Capacitor, 680 µF, 4 V","metaDescription":"KYOCERA AVX TPSD687K004R0100 molded tantalum capacitor, 680 µF, 4 V, ±10%, 100 mOhm ESR, 2917 case, -55 to 125°C.

This value determines the capacitor's self-heating under ripple current — a 100 mOhm ESR means the internal temperature rise is proportional to I² × 0.1, so a 2 A ripple current generates 0.4 W of heat inside the part. For a power-supply output filter, this ESR also sets the output ripple voltage: at 2 A ripple, the ripple voltage contribution from ESR alone is 200 mV."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSD687K004R0100","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSD687K004R0100 when reusing this data.
