Product details

4.7 µF / 10 V molded tantalum — the BOM-fit decision

This TAJB475K010RNJ is a molded tantalum capacitor in the TAJ series from KYOCERA AVX, rated at 4.7 µF with ±10% tolerance and a 10 V working voltage. The 4 Ohm ESR sets the ripple current ceiling and transient response floor for power rail decoupling — a 3.3 V rail sees a voltage drop of about 0.4 V at a 100 mA step load before the capacitor's internal resistance adds its own drop.

The molded case gives mechanical stability under vibration, and the 1411 (3528 Metric) footprint is a common two-pad land pattern that reflows without special paste stencil adjustments.

Listed as Active with no EOL or NRND notice. Sourced through independent distribution against your BOM quantity; current pricing and availability confirmed at RFQ time.

Frequently asked questions

What is the closest equivalent or replacement for TAJB475K010RNJ?

No official direct replacement or second source is listed by KYOCERA AVX. Capacitors with the same 4.7 µF, 10 V, ±10%, and B case size from other TAJ series variants may be functionally equivalent, but the 4 Ohm ESR must match for the same ripple current handling. Cross-reference against your BOM's derating requirement.
