The ±10% tolerance means the actual capacitance at the rail sits between 1.98 µF and 2.42 µF — enough margin for decoupling or timing circuits that need a predictable value. ## 4.5 Ohm ESR — what it means for ripple and heating The 4.5 Ohm ESR is the dominant thermal contributor in this capacitor. For a given ripple current I, the internal power dissipation is I² × 4.5 Ohm. If the circuit draws more than a few tens of mA RMS ripple, check the self-heating against the derating curve in the datasheet.","metaTitle":"TAJS225K020RNJ KYOCERA AVX TAJ Series 2.2 µF 20 V Molded","metaDescription":"TAJS225K020RNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor, 2.2 µF ±10%, 20 V rated, 4.5 Ohm ESR, 1206 case.","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":"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)":"0.047\\\" (1.20mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"S","ESR (Equivalent Series Resistance)":"4.5Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3089","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJS225K020RNJ/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJS225K020RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJS225K020RNJ when reusing this data.
