The TAJE477K010ANJ is a molded tantalum capacitor from the TAJ series, rated 470 µF at 10 V with ±10% tolerance and 500 mOhm ESR at 100 kHz. That ESR figure is the key thermal parameter: at ripple current, the I²R loss heats the part, and the 2000-hour endurance at 125°C assumes the internal temperature stays within the derating envelope. The 7.30 mm × 4.30 mm 2917 footprint is a standard size — board layout compatibility with existing pads is straightforward, but confirm the seated height of 4.30 mm clears adjacent components.
The TAJ series is a broad, long-running family — supply continuity is typical for this line.
Temperature range and life rating
The full military-temp band covers avionics, downhole instrumentation, and outdoor telecom equipment. At lower ambient temperatures, the expected life extends beyond the 2000-hour figure — the datasheet derating curve should be consulted for specific thermal profiles.
