The 900 mOhm ESR at 100 kHz sets the ripple current ceiling: at 35 V, the maximum ripple current is roughly 620 mA RMS before self-heating cuts into the 2000-hour lifetime at 125°C. For a switching regulator output, that ESR also defines the output ripple voltage — a 100 mV ripple target needs the cap to see less than 160 mA RMS ripple current. ## Temperature grade and endurance profile The 2000-hour endurance at 125°C is the standard JIS C 5141 / EIA-535 rating for tantalum MnO2 capacitors. At 85°C the lifetime derates to roughly 20000 hours; at 50°C it exceeds 100000 hours — the failure mode is wear-out of the dielectric, not a wear-out of the termination. 2917 (7343 Metric) case, size code D — 7.30 mm x 4.30 mm footprint, 3.10 mm seated height. The molded body has no exposed metal on the sides, so the anode and cathode terminations are at the ends only. The pad layout follows the standard 7343-31 footprint: a 1.27 mm gap between the anode and cathode pads, with the cathode pad extending 2.54 mm from the body edge. The moisture sensitivity level (MSL) for molded tantalums is MSL 3, so a bake is needed if the reel has been exposed to ambient humidity beyond the floor-life limit.","metaTitle":"TAJD476M035RNJV KYOCERA AVX TAJ Series 47 µF 35 V Molded","metaDescription":"47 µF, 35 V, ±20% tolerance, 900 mOhm ESR, 2917 (7343 Metric) package.

For a 47 µF nominal, that means the actual capacitance at 25°C and zero DC bias falls between 37.6 µF and 56.4 µF. Tantalum capacitors also lose capacitance with applied DC voltage — at 35 V the effective capacitance is roughly 70–80 % of the nominal value, so the in-circuit capacitance may be closer to 33–45 µF."},{"question":"Can I use a generic 47 µF 35 V tantalum capacitor as a replacement for TAJD476M035RNJV?","answer":"A 47 µF 35 V tantalum capacitor with the same case size (2917 / 7343-31) and ±20% tolerance is a functional match for the capacitance and voltage rating, but the ESR (900 mOhm) and the TAJ series' surge-current rating are specific to this part. If your circuit depends on a particular ESR for ripple control or inrush limiting, confirm the replacement's ESR is the same or lower — a lower ESR can cause higher inrush current at power-up and may stress the power supply or the capacitor itself."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJD476M035RNJV","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJD476M035RNJV when reusing this data.
