This is the standard tantalum chip size for medium-density boards — the same footprint as AVX's own TAJ-B and TPS-B series, so a layout swap between them is pad-compatible. The molded construction keeps the dielectric sealed against moisture ingress across that range.","metaTitle":"TAJB336M004RNJ – KYOCERA AVX TAJ Series 33 µF 4 V Molded","metaDescription":"TAJB336M004RNJ – 33 µF, 4 V, ±20%, molded tantalum chip, 1411 (3528) case, -55°C to +125°C, active production.","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":"±20%","Capacitance":"33 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"1411 (3528 Metric), 1210","Product Status":"Active","Voltage - Rated":"4 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)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3471","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TAJB336M004RNJ/alternatives.json"},"ai":{"faq":[{"question":"Is TAJB336M004RNJ polarized and what is the polarity marking?","answer":"Yes, it is polarized. The anode (+) is marked by a stripe or band on the body; the cathode end is unmarked. The polarity marking follows the standard tantalum chip convention — the stripe end is the positive terminal."},{"question":"Can TAJB336M004RNJ be replaced with a higher voltage or capacitance part?","answer":"A direct B-case replacement with higher voltage (e.g., TAJB336M006RNJ at 6.3 V) or higher capacitance (47 µF at 4 V) shares the same footprint, so a BOM substitution is pad-compatible. Confirm the ESR and ripple current rating for the new voltage/capacitance combination."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJB336M004RNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJB336M004RNJ when reusing this data.
