The B case code (1411 / 3528 Metric) measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max, making it a drop-in fit for standard 1210 footprint pads. For a 3.3 µF part, this ESR is typical — it means the capacitor is suited for decoupling and filtering where the AC component is modest, not for high-ripple power rails. The molded construction and tantalum dielectric hold capacitance and leakage within spec across the range, but the ESR rises at low temperature — expect roughly 2× the 25°C value at -55°C. This matters for timing circuits in avionics or downhole tools where the capacitor's RC time constant shifts with the cold. The part is in standard production and can be quoted to order against any BOM quantity.","metaTitle":"TAJB335K025SNJ — KYOCERA AVX Molded Tantalum 3.3 µF 25 V","metaDescription":"TAJB335K025SNJ: 3.3 µF, 25 V, ±10%, B-case (1411/1210), 3.5 Ohm ESR, -55°C to 125°C.

This is the typical value for a B-case 3.3 µF/25 V molded tantalum. At -55°C the ESR roughly doubles; at 125°C it decreases slightly. Use this figure to calculate ripple current derating — at 125°C the maximum ripple current is about 70 mA RMS before self-heating exceeds the limit."},{"question":"Is there a pin-compatible equivalent to TAJB335K025SNJ in the TAJ series?","answer":"Any B-case (1411/1210) tantalum capacitor with the same 3.3 µF, 25 V, ±10% rating from the TAJ series is a direct footprint match. The ESR may differ slightly by manufacturer — Kemet T491 series B-case parts are common cross-shopped alternatives. Confirm the ESR and temperature range against your ripple and derating requirements before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/kyocera-avx/TAJB335K025SNJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/kyocera-avx/TAJB335K025SNJ when reusing this data.
