What the 600 mOhm ESR means for your rail
The TPSB226K016H0600 is a molded tantalum capacitor from KYOCERA AVX's TPS series, rated at 22 µF with ±10% tolerance and a 16 V working voltage. For a 100 kHz switching regulator output, a 600 mOhm ESR means the capacitor can handle roughly 0.5 A ripple current before internal temperature rise becomes a concern — check the ripple current derating curve in the datasheet for your ambient.
The molded case and surface-mount 1411 (3528 Metric) package suit automated assembly and conformal coating in sealed enclosures.
