The E-size code means the maximum case height is 4.3 mm — confirm clearance under the nearest component or heatsink.","metaTitle":"KYOCERA AVX TPSE108M004R0040 Tantalum Cap, 1000 µF, 4 V","metaDescription":"KYOCERA AVX TPSE108M004R0040 molded tantalum capacitor, 1000 µF, 4 V, 40 mOhm ESR, -55°C to 125°C.

It determines the ripple current rating — lower ESR means higher ripple current capability and lower self-heating. For a 1000 µF cap on a 1.8 V rail, this ESR keeps the ripple voltage under 40 mV at 1 A ripple."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSE108M004R0040","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSE108M004R0040 when reusing this data.
