Product details

68 µF at 4 V — the bulk decoupling fit

The part holds its capacitance and ESR across avionics cold-soak, engine-bay ambient, and downhole tool temperatures without derating the voltage below 4 V.

Housed in a 2312 (6032 Metric) molded case, size code W — 6.00 mm x 3.20 mm footprint, 1.50 mm seated height. Surface-mount reflow profile follows the standard tantalum-capacitor ramp; the molded body absorbs moisture slower than uncoated chips, but a 24-hour bake at 125°C before reflow is still recommended if the tape has been exposed to humid air.

Frequently asked questions

Where can I find the datasheet for TAJW686K004RNJ?

The datasheet for the KYOCERA AVX TAJ series covers the full molded tantalum family. It includes the ESR vs. frequency curves, ripple-current derating, and reflow profile for the 2312 case. Request a copy with your RFQ.

What is the closest pin-compatible alternative to TAJW686K004RNJ in this Specialty Capacitors family?

Within the TAJ series, a same-case-size (W) alternative would share the 2312 footprint but differ in capacitance or voltage. No exact cross-reference is listed; the BOM position should be validated against the original manufacturer's recommended alternate ratings.
