The 2.5 Ohm ESR sets the ripple-current limit and the self-heating budget. For a 20 V rail with a few hundred mA of ripple, the I²R loss stays under 50 mW — the part runs cool. If your design pushes higher ripple, check the ESR against the power dissipation derating curve in the datasheet. ## Surface-mount footprint — 1411 (3528 Metric), size code B Package is 1411 (3528 Metric), size code B — 3.50 mm x 2.80 mm footprint, 2.10 mm seated height. The molded case has a clear polarity mark (the banded end is the anode). On a rework bench, a standard hot-air station at 260 °C for 10 seconds per joint is enough to swap it; no special nozzle needed.","metaTitle":"TAJB685M020RNJ KYOCERA AVX TAJ Series 6.8 µF 20 V Molded","metaDescription":"TAJB685M020RNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor: 6.8 µF, 20 V, ±20%, 2.5 Ohm ESR, -55 to 125 °C, 1411 package.","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":"6.8 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"1411 (3528 Metric), 1210","Product Status":"Active","Voltage - Rated":"20 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.138\\\" L x 0.110\\\" W (3.50mm x 2.80mm)","Height - Seated (Max)":"0.083\\\" (2.10mm)","Operating Temperature":"-55°C~125°C","Manufacturer Size Code":"B","ESR (Equivalent Series Resistance)":"2.5Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1749","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJB685M020RNJ/alternatives.json"},"ai":{"faq":[{"question":"How can I order TAJB685M020RNJ or check stock?","answer":"Submit an RFQ against your BOM line.

For under-hood or safety-critical automotive use, select a dedicated automotive-grade tantalum series."},{"question":"What is the closest alternative to TAJB685M020RNJ in the same package?","answer":"Within the TAJ series, other size-code B parts with the same 1411 footprint differ by capacitance and voltage. There is no single pin-compatible drop-in with identical ratings — the BOM position's capacitance and voltage must match.
