0.33 µF, 50 V — decoupling for a 48 V bus or 12 V rail with margin
The TAJT334M050RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 0.33 µF at 50 V with ±20% tolerance. The 50 V rating puts it comfortably above a 12 V or 24 V rail — even a 48 V bus stays within the 80 % derating guideline (40 V applied), leaving headroom for transients.
Military-temp range — -55 to +125 °C
At +125 °C the rated voltage must be derated per the manufacturer's curve — typically 67 % of 50 V (33.5 V) for continuous operation. For a 12 V rail this is still well within margin; for a 48 V bus the applied voltage should be checked against the derated limit at the maximum ambient temperature.
