The 3.5 Ohm ESR limits ripple current to roughly 200 mA RMS at 100 kHz, which is fine for a local bulk cap after a low-noise LDO but too high for a switching regulator output filter. In an engine-bay ECU or an avionics power supply, the capacitance stays within spec across the whole range — no voltage derating required at 125°C, though the ESR will rise with temperature. ## Active production — no EOL on the horizon No last-time-buy notice, no successor.","metaTitle":"TAJS226M004RNJ – KYOCERA AVX 22 µF 4 V Molded Tantalum","metaDescription":"TAJS226M004RNJ is an active KYOCERA AVX molded tantalum capacitor, 22 µF, 4 V, ±20%, 1206 case, -55°C 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":"22 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"1206 (3216 Metric)","Product Status":"Active","Voltage - Rated":"4 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)":"3.5Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJS226M004RNJ/alternatives.json"},"ai":{"faq":[{"question":"Can TAJS226M004RNJ be used as a replacement for a 22 µF 4 V tantalum capacitor in a 1206 package?","answer":"Yes.
