Wide-temperature tantalum for harsh-environment decoupling
The TAJA684K020HNJ is a Molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 0.68 µF ±10% at 20 V in a standard 1206 (3216 Metric) surface-mount package.
Capacitance and voltage fit for 12 V rails
At 0.68 µF and 20 V, this part provides bulk decoupling for a 12 V supply rail with 40% voltage derating margin — a common practice to improve reliability against surge and ripple. The 1206 footprint keeps the board area small while delivering enough capacitance for local bypass on a low-power MCU or op-amp supply.
