The 1.8 Ohm ESR at 100 kHz sets the ripple current ceiling: at 35 V, the cap can handle roughly 400 mA ripple without exceeding its internal temperature rise. For a buck converter switching at 500 kHz, that ESR also dominates the output ripple voltage — expect about 18 mV ripple per amp of inductor ripple current. The 2312 (6032 metric) case is a rework-friendly size — 6.00 mm x 3.20 mm with a seated height of 2.80 mm. Under hot air at 260 °C, the part lifts cleanly after about 8 seconds if the board has a thermal relief on the anode pad. The silver-palladium termination wets well with Sn63Pb37 or SAC305; just watch for tombstoning if one pad heats faster than the other. No exposed paddle to worry about — it's a two-terminal part. The molded case is not hermetically sealed — if the board sees condensing humidity, conformal coat over the cap body is advised to prevent silver migration on the terminations. No last-time-buy window to track; no successor to qualify.","metaTitle":"TAJC685K035RNJ – KYOCERA AVX Molded Tantalum Cap, 6.8 µF","metaDescription":"TAJC685K035RNJ from KYOCERA AVX: Molded tantalum capacitor, 6.8 µF, 35 V, ±10%, 1.8 Ohm ESR, -55°C to 125°C, 2312 (6032) case.","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":"6.8 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"2312 (6032 Metric)","Product Status":"Active","Voltage - Rated":"35 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)":"1.8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJC685K035RNJ/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TAJC685K035RNJ and how is it quoted?","answer":"This part is Active and available through independent distribution.
