The 680 µF capacitance provides enough bulk storage to hold up a 3.3 V rail through a load transient of several amps for tens of microseconds.","metaTitle":"KYOCERA AVX TPSE687M004R0040 TPS 680 µF 4 V 40 mOhm Molded","metaDescription":"KYOCERA AVX TPS series molded tantalum capacitor, 680 µF ±20%, 4 V rated, 40 mOhm ESR, 2917 (7343 Metric) case, E code, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Specialty Capacitors"],"specifications":{"Mfr":"KYOCERA AVX","Type":"Molded","Series":"TPS","Package":"Tape & Reel (TR)","Features":"General Purpose","Tolerance":"±20%","Capacitance":"680 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"2917 (7343 Metric)","Product Status":"Active","Voltage - Rated":"4 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.287\\\" L x 0.169\\\" W (7.30mm x 4.30mm)","Height - Seated (Max)":"0.169\\\" (4.30mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"E","ESR (Equivalent Series Resistance)":"40mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0952","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b00017213ae4c6777a643c3e703ff6ae.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPSE687M004R0040/alternatives.json"},"ai":{"faq":[{"question":"What is the ESR of TPSE687M004R0040 and why does it matter?","answer":"The ESR is 40 mOhm. This is the key parameter for a bulk tantalum used on a power rail — it determines how much AC ripple current the capacitor can handle before the internal temperature rise exceeds the derating curve. At 40 mOhm, this part suits output filtering on low-voltage DC-DC converters where ripple current is in the 1-2 A range."},{"question":"What package and case code does TPSE687M004R0040 use?","answer":"It uses the 2917 (7343 Metric) surface-mount package with manufacturer size code E."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSE687M004R0040","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSE687M004R0040 when reusing this data.
