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.
