The 1206 case (3.20 mm x 1.60 mm footprint) is a common size for board-level decoupling, filtering, and energy storage in circuits that need a stable capacitance over temperature. In a DC-DC output filter, this ESR will contribute to the output ripple voltage — the voltage ripple equals the inductor ripple current multiplied by the ESR. For a 100 mA ripple, that is 400 mV of ripple, which may be too high for a sensitive analog rail without additional post-filtering. No surplus or spot-market premium applies unless the order volume exceeds typical distributor stock depth. ## Package and footprint — 1206 surface-mount The 1206 (3216 Metric) case measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm max.","metaTitle":"TAJA475J020RNJ KYOCERA AVX 4.7 µF 20 V Molded Tantalum","metaDescription":"TAJA475J020RNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor: 4.7 µF, 20 V, ±5%, 1206 case, 4 Ohm ESR, -55 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":"±5%","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJA475J020RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJA475J020RNJ when reusing this data.
