Product details

15 µF, 20 V, 2 Ohm ESR — molded tantalum for bulk decoupling

The 2 Ohm ESR at 100 kHz sets the ripple current capability and self-heating under AC load — for a 15 µF part at 20 V, this ESR is typical for the B case size and keeps power dissipation within the 0.085 W limit for reliable operation up to 125°C.

1411 (3528 Metric) footprint — B case size

Package is 1411 (3528 Metric), manufacturer size code B, with dimensions 3.50 mm x 2.80 mm and a seated height of 2.10 mm max.

The 20 V rated voltage is derated per MIL-PRF-55365 guidelines — at 125°C, apply 50% derating (10 V max) for long-life reliability. For automotive under-hood use, the 125°C ceiling provides margin above the 105°C typical ambient.

Frequently asked questions

What is the footprint of TAJB156K020A?

The package is 1411 (3528 Metric), size code B. The body measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. Standard reflow soldering applies; the part is supplied on tape and reel.

Can TAJB156K020A replace TAJB156K020?

TAJB156K020 is a prior suffix variant in the same TAJ series. The 'A' suffix on TAJB156K020A typically indicates a packaging or termination finish update (e.g., RoHS compliance). Electrical ratings (15 µF, 20 V, ±10%, 2 Ohm ESR) and footprint (B case, 1411) are identical. Confirm the specific suffix definition in the KYOCERA AVX datasheet, but for most BOM positions the two are drop-in interchangeable.
