The capacitance and ESR shift across the range — at -55°C the ESR rises and the capacitance drops, so the ripple current derating must account for the cold corner. At +125°C the leakage current increases, reducing the safe operating voltage below the 20 V rating. The part can be quoted to order for volume BOM quantities through independent distribution — no last-time-buy window to schedule. ## 2917 (7343 Metric) — footprint and layout The D case size measures 7.30 mm x 4.30 mm with a seated height of 3.10 mm max. The 2917 (7343 Metric) footprint is standard for tantalum capacitors in this density range — the pad layout on the PCB should follow the manufacturer's recommended land pattern to avoid tombstoning during reflow.","metaTitle":"TAJD476M020SNJ KYOCERA AVX TAJ Series 47 µF 20 V Molded","metaDescription":"Active KYOCERA AVX TAJD476M020SNJ: 47 µF, 20 V, 900 mOhm ESR, 2917 (7343 Metric) 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)","Features":"General Purpose","Tolerance":"±20%","Capacitance":"47 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"2917 (7343 Metric)","Product Status":"Active","Voltage - Rated":"20 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)":"900mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2909","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJD476M020SNJ/alternatives.json"},"ai":{"faq":[{"question":"Is the TAJD476M020SNJ equivalent to the T491D476M020AT?","answer":"Both are 47 µF, 20 V, D case size molded tantalum capacitors.
