Product details

Core ratings for BOM fit

0.47 µF capacitance at ±10% tolerance with a 50 V DC rated voltage — the 50 V ceiling provides margin over typical 12 V, 24 V, and 48 V rails, keeping the derating factor above 0.5 for reliability in aerospace and industrial power buses. 9.5 Ohm ESR at 25°C sets the ripple current ceiling — for a 100 kHz switching regulator output, the self-heating from ripple current stays within the 125°C rated limit when the RMS current is kept under the datasheet ripple-current curve.

1206 (3216 Metric) molded case, size code A — the 3.20 mm x 1.60 mm footprint matches standard pick-and-place feeders and reflow profiles. The 1.80 mm seated height fits tight card cages and mezzanine stacks without clearance issues.

Frequently asked questions

Can TAJA474K050RNJ replace TAJA474K035RNJ?

Both are TAJ series molded tantalum capacitors with the same 0.47 µF capacitance, ±10% tolerance, and 1206 case. The key difference is voltage rating: TAJA474K050RNJ is rated 50 V, while TAJA474K035RNJ is rated 35 V. The 50 V part can replace the 35 V part in any circuit where the applied voltage does not exceed 35 V, providing extra derating margin. The reverse substitution is not allowed unless the circuit voltage never exceeds 35 V.

What is the footprint of TAJA474K050RNJ?

The case is 1206 (3216 Metric) with dimensions 3.20 mm x 1.60 mm and a seated height of 1.80 mm. The manufacturer size code is A. The footprint matches standard 1206 solder pads per IPC-7351B (CAPC3216X180).
