The ±20% tolerance is typical for tantalum electrolytics; the actual capacitance at the 4 V bias will sit near the nominal value, not at the low end, because tantalum dielectrics lose capacitance with applied voltage. The TAJ series is a long-running molded tantalum platform from KYOCERA AVX, widely second-sourced by Kemet and Vishay in the same case size and ratings. For a BOM that needs 680 µF on a 4 V rail, this order code is a safe design-in choice without a last-time-buy clock. ## Full military temperature span — avionics and downhole ready In an avionics power supply or a downhole instrument that sees 125°C ambient, the capacitor's leakage current and ESR shift within the datasheet envelope — no need to derate the voltage rating below 4 V unless the application exceeds the manufacturer's derating guidelines (typically 50% at 125°C).","metaTitle":"TAJD687M004RNJ KYOCERA AVX TAJ Series 680 µF Molded","metaDescription":"TAJD687M004RNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor, 680 µF, 4 V, ±20%, 500 mOhm ESR, 2917 package, -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":"TAJ","Package":"Tape & Reel (TR) Cut Tape (CT)","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)":"0.122\\\" (3.10mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"D","ESR (Equivalent Series Resistance)":"500mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJD687M004RNJ/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJD687M004RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJD687M004RNJ when reusing this data.
