The molded epoxy body suits general-purpose board-level decoupling and filtering where the 4 V rail is stable and the ESR budget is known. This is a production-grade part, not a last-time-buy or obsolete line. No single pin-compatible alternative is listed, but other manufacturers offer functionally equivalent molded tantalum capacitors in the same 6032-28 case code — a BOM review against the ESR and voltage rating is the right cross-check before committing. This capacitor can sit in an avionics power supply, a downhole instrument, or a satellite payload where the ambient swings from cold-soak to internal heat. The molded construction and the TAJ series' field history support that range without derating on the voltage side at 125 °C.","metaTitle":"TAJC227M004RNJ KYOCERA AVX TAJ Series 220 µF 4 V Molded","metaDescription":"TAJC227M004RNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor: 220 µF, 4 V, 1.2 Ohm ESR, -55 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":"220 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"2312 (6032 Metric)","Product Status":"Active","Voltage - Rated":"4 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.236\\\" L x 0.126\\\" W (6.00mm x 3.20mm)","Height - Seated (Max)":"0.110\\\" (2.80mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"C","ESR (Equivalent Series Resistance)":"1.2Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJC227M004RNJ/alternatives.json"},"ai":{"faq":[{"question":"Is TAJC227M004RNJ obsolete or end-of-life?","answer":"No. KYOCERA AVX lists the product status as Active.
