At 100 mOhm, this part handles ripple currents that a standard tantalum of the same capacitance and voltage rating would overheat on. Under 4 V DC bias the effective capacitance drops roughly 20-30%, a derating the designer must budget into the loop compensation.","metaTitle":"KYOCERA AVX TPSD477M004H0100 Tantalum Cap, 470 µF, 4 V","metaDescription":"KYOCERA AVX TPSD477M004H0100 molded tantalum capacitor, 470 µF, 4 V, 100 mOhm ESR at 100 kHz. 2917 case, -55 to 125°C.

This is the key spec for a bulk decoupling cap on a switching regulator — the output ripple voltage equals the ripple current multiplied by the ESR. A 100 mOhm ESR keeps ripple under control for typical converter designs without excessive self-heating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSD477M004H0100","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSD477M004H0100 when reusing this data.
