The 50 V rating on a 1 µF part gives significant derating headroom for 12 V and 24 V supplies, reducing the DC bias capacitance loss that plagues MLCCs at high voltage. However, the 7 Ohm ESR is higher than a typical MLCC of the same value — this matters for ripple current handling and filter cutoff frequency. The MnO₂ cathode does not suffer from the capacitance derating at low temperature that polymer tantalums exhibit, making it a reliable choice for cold-start circuits. Listed as Active — no last-time-buy or obsolescence pressure. KYOCERA AVX continues to produce this TAJ series part, so it remains eligible for new designs.","metaTitle":"TAJB105M050YNJ – KYOCERA AVX Molded Tantalum, 1 µF, 50 V","metaDescription":"TAJB105M050YNJ from KYOCERA AVX: 1 µF ±20% molded tantalum capacitor, 50 V rated, B case (1411/1210), 7 Ohm ESR, -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":"1 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"1411 (3528 Metric), 1210","Product Status":"Active","Voltage - Rated":"50 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.138\\\" L x 0.110\\\" W (3.50mm x 2.80mm)","Height - Seated (Max)":"0.083\\\" (2.10mm)","Operating Temperature":"-55°C~125°C","Manufacturer Size Code":"B","ESR (Equivalent Series Resistance)":"7Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order TAJB105M050YNJ or check availability?","answer":"Submit an RFQ for current pricing and lead-time confirmation."},{"question":"What are the exact specifications of TAJB105M050YNJ?","answer":"Molded tantalum, 1 µF ±20%, 50 V rated, B case (1411/3528 Metric), 7 Ohm ESR, operating temperature -55°C to 125°C, Tape & Reel packaging.
