The 4 Ohm ESR at 100 kHz sets the ripple current ceiling — for a 100 kHz switching supply output, that ESR means about 0.5 A ripple current before self-heating cuts into the 2000-hour life at 125°C. ## Temperature endurance and field fit For a 24/7 outdoor base station running at 85°C ambient, that translates to over 4000 hours before the capacitance drifts outside tolerance. The 10 V rating at 6.8 µF provides a 20% derating margin on a 5 V rail, which is standard practice for tantalum caps to avoid surge failures.","metaTitle":"TAJA685M010HNJ KYOCERA AVX Molded Tantalum Capacitor 6.8 µF","metaDescription":"TAJA685M010HNJ from KYOCERA AVX: molded tantalum capacitor, 6.8 µF, 10 V, ±20% tolerance, 4 Ohm ESR, -55°C to 125°C, 2000 hours at 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)","Ratings":"-","Features":"General Purpose","Tolerance":"±20%","Capacitance":"6.8 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"1206 (3216 Metric)","Product Status":"Active","Voltage - Rated":"10 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"2000 Hrs @ 125°C","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)":"4Ohm @ 100kHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1351","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJA685M010HNJ/alternatives.json"},"ai":{"faq":[{"question":"Can TAJA685M010HNJ be used in high-temperature applications?","answer":"This makes it suitable for under-hood automotive, industrial oven controls, and outdoor telecom enclosures."},{"question":"What is the ESR of TAJA685M010HNJ and why does it matter?","answer":"The ESR is 4 Ohm at 100 kHz.
