It suits low-ripple bypass or timing applications where ESR is not the dominant loss. In an engine bay ambient of 105 °C, the 25 V rating still provides derating headroom.","metaTitle":"TAJA475K025RNJ KYOCERA AVX 4.7 µF 25 V Molded Tantalum","metaDescription":"TAJA475K025RNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor, 4.7 µF ±10%, 25 V, 3.1 Ohm ESR, 1206 package, -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":"±10%","Capacitance":"4.7 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"1206 (3216 Metric)","Product Status":"Active","Voltage - Rated":"25 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.126\\\" L x 0.063\\\" W (3.20mm x 1.60mm)","Height - Seated (Max)":"0.071\\\" (1.80mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"A","ESR (Equivalent Series Resistance)":"3.1Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJA475K025RNJ/alternatives.json"},"ai":{"faq":[{"question":"What is the footprint of TAJA475K025RNJ?","answer":"It uses the standard 1206 (3216 Metric) footprint: 3.20 mm x 1.60 mm body, 1.80 mm seated height.
