Product details

The TAJS156M006RNJ is a molded tantalum capacitor from the TAJ series, rated 15 µF at 6.3 V with ±20% tolerance. The 1206 (3216 Metric) case is the standard footprint for this density and voltage — it fits the same land pattern as other 1206 tantalum capacitors, so a BOM swap to a different manufacturer's 15 µF/6.3 V 1206 part requires no board layout change.

For a 15 µF capacitor on a 6.3 V rail, this ESR is typical for the case size — it keeps the output ripple voltage within a few tens of millivolts for most decoupling and bulk-filtering applications. If the design requires lower ESR for higher ripple current (e.g., a switching regulator output), a TPS or other low-ESR series would be a better fit.

The molded case provides mechanical stability across the temperature cycle.

Frequently asked questions

Is TAJS156M006RNJ active or obsolete?

Active. KYOCERA AVX lists this part as in production with no end-of-life notice. It is suitable for new designs and ongoing BOM replenishment.

What is the case size of TAJS156M006RNJ?

1206 (3216 Metric) — 0.126" x 0.063" (3.20 mm x 1.60 mm) with a seated height of 0.047" (1.20 mm). Manufacturer size code S.

What is the ESR of TAJS156M006RNJ?

4 Ohm equivalent series resistance.

Can TAJS156M006RNJ be replaced with a TPS series tantalum capacitor?

The TPS series from KYOCERA AVX is a low-ESR alternative in the same 1206 case. A TPS part with the same 15 µF and 6.3 V rating would have lower ESR (typically 1-2 Ohm) and higher ripple current capability. The footprint is identical, so a board layout change is not required — but confirm the voltage derating and ripple current requirements before substituting.
