Housed in a 2312 (6032 Metric) molded case, size code W — 6.00 mm x 3.20 mm footprint, 1.50 mm seated height. Surface-mount reflow profile follows the standard tantalum-capacitor ramp; the molded body absorbs moisture slower than uncoated chips, but a 24-hour bake at 125°C before reflow is still recommended if the tape has been exposed to humid air. ## Lifecycle — no LTB clock ticking","metaTitle":"TAJW686K004RNJ KYOCERA AVX 68 µF 4 V Molded Tantalum","metaDescription":"TAJW686K004RNJ from KYOCERA AVX: 68 µF, 4 V, ±10%, 2312 (6032 Metric), 400 mOhm ESR, -55°C to 125°C, Active.","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":"±10%","Capacitance":"68 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)":"0.059\\\" (1.50mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"W","ESR (Equivalent Series Resistance)":"400mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6304","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJW686K004RNJ/alternatives.json"},"ai":{"faq":[{"question":"Where can I find the datasheet for TAJW686K004RNJ?","answer":"The datasheet for the KYOCERA AVX TAJ series covers the full molded tantalum family.
