The 4.5 Ohm ESR is on the higher side for a 2.2 µF tantalum — expect more self-heating under ripple current than a low-ESR polymer would deliver. That matters if the cap sits on a switching regulator output with significant AC content. ## Molded case, size code B — footprint and temperature range Molded construction in the 1411 (3528 Metric) / 1210 case, size code B, with dimensions 3.50 mm x 2.80 mm and seated height 2.10 mm.","metaTitle":"TAJB225K025H KYOCERA AVX Molded Tantalum Capacitor 2.2 µF","metaDescription":"TAJB225K025H is an active KYOCERA AVX molded tantalum capacitor, 2.2 µF ±10%, 25 V, 4.5 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":"±10%","Capacitance":"2.2 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"1411 (3528 Metric), 1210","Product Status":"Active","Voltage - Rated":"25 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)":"4.5Ohm"}},"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/TAJB225K025H/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJB225K025H","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJB225K025H when reusing this data.
