The 50 mOhm ESR is the spec that governs ripple. At a 500 kHz switching frequency with 2 A ripple current, that ESR contributes 100 mV of ripple voltage at the capacitor terminals — well within the tolerance of most downstream logic, but a higher-ESR part would push the ripple above the 3.3 V rail's allowable droop. ## Temperature grade and operating envelope Rated for -55°C to 125°C, this is a full military-temperature-range tantalum. The capacitance and ESR shift with temperature — expect capacitance to drop about 10-15% at -55°C and ESR to rise, though the TPS series is formulated to keep the ESR curve flatter than standard MnO2 tantalums across the band. Tantalum capacitors are typically derated to 50-60% of rated voltage for reliable operation; at 4 V, a 2.5 V rail is at 62.5% derating, which is within the standard practice for molded MnO2 types. It remains in the current TPS series catalog and is available through authorized distribution channels. Sourced to order against BOM quantities. Pricing and lead time confirmed at RFQ; no stock-holding claim or immediate-shipment promise. The part is genuine KYOCERA AVX with full lot traceability and manufacturer warranty when sourced through the authorized chain.","metaTitle":"TPSE158M004R0050 KYOCERA AVX TPS 1500 µF 4 V Molded Tantalum","metaDescription":"TPSE158M004R0050 KYOCERA AVX TPS series molded tantalum capacitor, 1500 µF, 4 V, ±20%, 50 mOhm ESR, 2917 case, -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":"1500 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)":"50mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0130","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b00017213ae4c6777a643c3e703ff6ae.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPSE158M004R0050/alternatives.json"},"ai":{"faq":[{"question":"What is the ESR of TPSE158M004R0050 and why does it matter?","answer":"The equivalent series resistance is 50 mOhm. This is a low-ESR part for the capacitance value — it keeps ripple voltage low on a DC-DC converter output and reduces self-heating from ripple current. A higher ESR would increase output ripple and shorten capacitor life at the same ripple current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TPSE158M004R0050","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TPSE158M004R0050 when reusing this data.
