Rated at 6.8 µF with ±10% tolerance and a 25 V DC voltage rating, this part fits bulk decoupling on 12 V or 5 V rails, hold-up capacitors in power supplies, and output filtering in low-dropout regulators. The 2 Ohm ESR at 100 kHz limits ripple current capacity — expect around 300 mA ripple current at 85°C, derating further at higher ambient. The voltage derating curve in the TAJ series datasheet recommends staying below 2/3 of rated voltage above 85°C to maintain reliability. No direct pin-compatible replacement is listed — the TAJ series covers a range of capacitance and voltage combinations, but each size code (C case) and rating is a distinct order code.","metaTitle":"TAJC685K025RNJ – KYOCERA AVX 6.8 µF 25 V Molded Tantalum","metaDescription":"TAJC685K025RNJ from KYOCERA AVX: 6.8 µF, 25 V, ±10% tolerance, 2 Ohm ESR, -55°C to 125°C, molded tantalum in 2312 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":"25 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)":"2Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJC685K025RNJ/alternatives.json"},"ai":{"faq":[{"question":"Can TAJC685K025RNJ be replaced by a ceramic capacitor?","answer":"A 6.8 µF ceramic MLCC in a 1206 or 1210 package may fit the same footprint with a voltage derating adjustment, but the DC bias characteristic of Class 2 ceramics (X5R/X7R) means effective capacitance drops sharply at 25 V — often below 50% of nominal. Tantalum holds its capacitance across the voltage range, which matters for hold-up timing or filter cutoff stability. The 2 Ohm ESR of this tantalum also differs from the sub-10 mOhm ESR of a ceramic, affecting ripple attenuation and loop stability in regulator designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJC685K025RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJC685K025RNJ when reusing this data.
