Molded tantalum cap for harsh-environment rails
The TPSB156K016H0800 is a molded tantalum capacitor from KYOCERA AVX's TPS series, rated 15 µF at 16 V with ±10% tolerance and 800 mOhm ESR.
ESR and ripple current budget
For a 100 kHz buck converter output, the I²R loss at 500 mA ripple is 0.2 W; the 2.1 mm seated height in a 1411 case dissipates that without exceeding the 125 °C limit, provided the board copper area follows the datasheet thermal model.
