Automotive-grade tantalum for 50 V rails
The TAJC225K050TNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 2.2 µF with ±10% tolerance and a 50 V working voltage. In a 12 V input filter for a DC-DC converter, this ESR limits self-heating; at 50 V the part also serves as a bulk capacitor on 48 V telecom or automotive bus rails.
2000-hour endurance at 125°C
The 125°C endurance figure is the derating anchor: at 105°C ambient the expected life extends well beyond 2000 hours, but at 125°C the part should be budgeted for the stated lifetime.
Package and mounting: 2312 case, tape and reel
Supplied in 2312 (6032 metric) case size, manufacturer code C, with seated height 2.80 mm max.
