The 20 V rating gives headroom on a 12 V or 5 V rail — you can run it at 80 % derating per MIL-PRF-55365 guidelines and still stay below the voltage limit. The 5.3 Ohm ESR is the number that sets ripple current capability: at 100 kHz, the allowed ripple current is roughly the square root of (power dissipation divided by ESR). For a typical 0.1 W dissipation limit in free air, that works out to about 133 mA RMS — enough for output filtering on a low-power DC-DC converter. ## Rework and board-fit notes Molded 1206 case — 3.20 mm x 1.60 mm footprint, 1.80 mm seated height. The body is solid epoxy, so it takes reflow soldering without cracking if the preheat ramp is controlled. The capacitance change with temperature is roughly ±10 % over that span — the 2.2 µF nominal value holds within spec at cold soak and under the hood.","metaTitle":"TAJA225K020RNJ KYOCERA AVX 2.2 µF 20 V Molded Tantalum","metaDescription":"TAJA225K020RNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor: 2.2 µF, 20 V, ±10%, 5.3 Ohm ESR, -55°C to 125°C, 1206 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":"2.2 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)":"0.071\\\" (1.80mm)","Operating Temperature":"-55°C~125°C","Manufacturer Size Code":"A","ESR (Equivalent Series Resistance)":"5.3Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJA225K020RNJ/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJA225K020RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJA225K020RNJ when reusing this data.
