That is a standard ESR for a small-case tantalum at this capacitance and voltage — expect ripple current handling around the 100-200 mA range at 100 kHz before self-heating cuts into the 125 °C lifetime."},{"question":"Does TAJR475M006RNJV require voltage derating?","answer":"Industry practice for tantalum capacitors is to derate to 50-60 % of rated voltage for reliable operation. At 6.3 V rated, a 3.3 V rail is safe; a 5 V rail leaves only 1.3 V headroom, which increases the failure rate under surge or ripple conditions."},{"question":"What is the closest alternative to TAJR475M006RNJV in the TAJ series?","answer":"The TAJ series includes many 4.7 µF, 6.3 V parts in different case sizes (A, B, C, D). The R case (0805) is the smallest; a B case (1206) alternative would have lower ESR and higher ripple current capability but a larger footprint. No pin-compatible issue — it is a capacitor, not an IC."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJR475M006RNJV","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJR475M006RNJV when reusing this data.
