Molded tantalum — 15 µF, 20 V, 450 mOhm ESR
The TPSC156K020R0450 is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated at 15 µF with ±10% tolerance and a 20 V working voltage. The 450 mOhm equivalent series resistance (ESR) at 100 kHz sets the ripple current limit and self-heating floor — a lower ESR means less I²R loss for the same AC current, which directly affects the capacitor's temperature rise in a switching regulator output or decoupling bank.
The molded case and surface-mount 2312 (6032 Metric) footprint keep the assembly compatible with standard reflow profiles.
