Product details

Molded Tantalum, 1 µF at 20 V — the TAJ footprint for low-ESR bypass

The TAJA105M020RNJ is a molded tantalum capacitor from the TAJ series by KYOCERA AVX, offering 1 µF capacitance with ±20% tolerance in the compact 1206 (3216 Metric) case size. Rated at 20 V with a 9 Ohm ESR, this part suits decoupling and filtering roles where the ESR ceiling sets the ripple current budget — the 9 Ohm figure is the floor for power dissipation at the operating frequency.

Sourcing this part against your BOM line

The 1206 footprint is a standard size, so board layout is straightforward; the molded case provides mechanical stability during reflow and handling.

Frequently asked questions

What is the ESR of TAJA105M020RNJ and why does it matter?

The ESR is 9 Ohm. This value sets the ripple current the capacitor can handle before self-heating exceeds the temperature rating — higher ESR means more internal loss at a given ripple current, so the derating curve must be checked against the circuit's AC current.
