The 20 V rating on a 1206 case gives enough derating headroom for a 12 V rail — typical practice is to derate tantalums by 50% for DC bias, so this part comfortably covers a 10 V bus. With a 12 Ohm ESR, this cap is suited for decoupling, filtering, and timing circuits where moderate series resistance is acceptable — not for high-ripple bulk storage where lower ESR is needed to keep self-heating in check. The full -55 to 125 °C temperature range means the capacitor is qualified for the same thermal envelope as military-grade ICs and ceramic passives, simplifying derating analysis on a mixed-technology board.","metaTitle":"TAJS105M020RNJ – KYOCERA AVX TAJ 1 µF 20 V Molded Tantalum","metaDescription":"Active-production TAJ-series tantalum cap: 1 µF, 20 V, ±20%, 1206 case, 12 Ohm ESR, -55 to 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)","Features":"General Purpose","Tolerance":"±20%","Capacitance":"1 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"1206 (3216 Metric)","Product Status":"Active","Voltage - Rated":"20 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.126\\\" L x 0.063\\\" W (3.20mm x 1.60mm)","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"S","ESR (Equivalent Series Resistance)":"12Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2897","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJS105M020RNJ/alternatives.json"},"ai":{"faq":[{"question":"Is TAJS105M020RNJ suitable for high-reliability applications like aerospace?","answer":"The -55 to 125 °C operating range and molded construction make it usable in military-temperature environments, but it is a standard TAJ-series part without MIL-spec screening or JAN qualification. For defence or space programs requiring full lot traceability and burn-in, request the MIL-grade equivalent from the same series."},{"question":"What is the closest equivalent to TAJS105M020RNJ if I need a lower ESR?","answer":"Within the same TAJ series, a larger case size (e.g., 1210 or 2312) at the same 1 µF and 20 V rating will typically offer lower ESR. No direct pin-compatible drop-in exists — the pad footprint changes with case size, so a board layout change is required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJS105M020RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJS105M020RNJ when reusing this data.
