For a typical 100 kHz switching regulator output, that ESR means the capacitor dissipates about 0.5 W at 400 mA ripple, which is within the 2000-hour endurance at 125 °C. ## D case 2917 — footprint and board fit The D case size (7.30 mm x 4.30 mm, 3.10 mm seated height) is the standard 2917 footprint. The surface-mount pad layout follows the EIA-7343-31 pattern — the same footprint used by most 2917 tantalum capacitors, so swapping in another D-case TAJ part is a straight BOM change. ## Active — no EOL clock ticking","metaTitle":"TAJD225K050HNJ — KYOCERA AVX TAJ 2.2 µF 50 V Molded","metaDescription":"Active KYOCERA AVX TAJ series molded tantalum capacitor, 2.2 µF ±10%, 50 V, 2.5 Ohm ESR, D case 2917.","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)","Ratings":"-","Features":"General Purpose","Tolerance":"±10%","Capacitance":"2.2 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"2917 (7343 Metric)","Product Status":"Active","Voltage - Rated":"50 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"2000 Hrs @ 125°C","Size / Dimension":"0.287\\\" L x 0.169\\\" W (7.30mm x 4.30mm)","Height - Seated (Max)":"0.122\\\" (3.10mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"D","ESR (Equivalent Series Resistance)":"2.5Ohm @ 100kHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5682","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJD225K050HNJ/alternatives.json"},"ai":{"faq":[{"question":"What is the direct replacement for TAJD225K050HNJ?","answer":"No direct replacement is listed by the manufacturer.
