Molded tantalum, 1.5 µF at 20 V — 1206 case
The TAJA155K020H is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 1.5 µF with ±10% tolerance and a 20 V DC rated voltage. The 1206 (3216 Metric) surface-mount package (3.20 mm x 1.60 mm footprint, 1.80 mm seated height) fits standard PCB layouts for bypass, coupling, or timing functions where a moderate capacitance and voltage rating are needed. The 6.5 Ohm ESR (Equivalent Series Resistance) is a key parameter — it limits the ripple current the capacitor can handle and contributes to output voltage ripple in power-supply decoupling. For a 1.5 µF part at 20 V, this ESR is typical for the case size and voltage rating; expect higher self-heating under AC ripple compared to lower-ESR tantalum or ceramic alternatives. The molded construction provides mechanical robustness against vibration and thermal cycling.
