The 4 Ohm ESR is the key derating parameter: it limits the ripple current the part can handle before self-heating raises the internal temperature above the 125°C ceiling. For a 100 kHz buck converter output, the ripple current through this cap should stay under the thermal budget — the ESR sets the I²R loss, not the capacitance alone. A downhole tool or satellite power bus that sees -55°C startup and 125°C during re-entry can use this cap without derating the voltage below 20 V.","metaTitle":"TAJA475K020Y KYOCERA AVX Molded 4.7 µF 20 V 1206 Capacitor","metaDescription":"TAJA475K020Y from KYOCERA AVX — TAJ series molded tantalum capacitor, 4.7 µF ±10%, 20 V, 4 Ohm ESR, 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":"±10%","Capacitance":"4.7 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)":"4Ohm"}},"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/TAJA475K020Y/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TAJA475K020Y?","answer":"Available through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJA475K020Y","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJA475K020Y when reusing this data.
