Molded tantalum for tight-tolerance filtering
The TAJA225J016RNJ is a molded tantalum capacitor from KYOCERA AVX's TAJ series, offering 2.2 µF capacitance with ±5% tolerance and a 16 V voltage rating. The 6.5 Ω ESR (Equivalent Series Resistance) is the key parameter for decoupling and ripple filtering — a higher ESR damps resonant peaking but also increases self-heating under AC ripple.
The molded case provides mechanical protection against vibration and moisture ingress.
