Automotive-grade 2.2 µF tantalum in 1206
The TAJA225K010TNJ is a Molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 2.2 µF at 10 V with ±10% tolerance. The 1206 (3216 Metric) footprint is a standard size for power-supply decoupling and signal filtering in engine control units, infotainment, and ADAS sensor modules.
7 Ohm ESR and temperature range
ESR is 7 Ohm at 100 kHz — this is the AC resistance that generates heat under ripple current. For a 2.2 µF capacitor at 10 V, the ESR limits the ripple current rating; in a typical automotive DC-DC converter output filter, derate the ripple current to keep self-heating below 10°C.
