Product details

22 µF at 20 V — B-case molded tantalum

The TAJB226K020HNJ: This is a 22 µF, 20 V molded tantalum capacitor from the KYOCERA AVX TAJ series, housed in the B case size (1411 / 3528 Metric). The 20 V rating leaves headroom on a 12 V or 5 V rail — a 50 % derating guideline for tantalum means the applied voltage should stay below 13.3 V for this part, which covers most 12 V bus applications.

2000-hour endurance at 125°C

1.8 Ω ESR — what it means for ripple

A 1.8 Ω ESR is typical for a B-case tantalum — adequate for output filtering on a low-ripple LDO or as bulk storage on a moderate-load rail, but not suited for high-ripple switch-mode inputs where a polymer or ceramic would be a better fit.

Listed as Active on the manufacturer's lifecycle status.

Frequently asked questions

Where can I find the datasheet for TAJB226K020HNJ?

The datasheet is available from the manufacturer KYOCERA AVX under the TAJ series. The key ratings are 22 µF, 20 V, ±10%, B case, 1.8 Ω ESR at 100 kHz, and 2000 hours at 125°C. We can provide the datasheet upon request with your RFQ.

What is the closest equivalent to TAJB226K020HNJ in the TAJ series?

A direct equivalent within the same TAJ series is TAJB226K020K, which shares the same 22 µF capacitance, 20 V rating, B case size, and ±10% tolerance. The suffix difference (HNJ vs K) typically indicates packaging or RoHS compliance variant — confirm the specific termination finish and reel quantity before substituting.
