Active production — 100 µF, 4 V, 100 mOhm ESR
The TPSW107K004R0100: Its 100 mOhm equivalent series resistance (ESR) at 100 kHz sets the ripple-current ceiling and self-heating budget — a lower ESR means less internal temperature rise for a given AC ripple, which matters when the capacitor sits near a hot regulator or inductor.
Package and board-fit — 2312 (6032 Metric), size code W
The molded case provides mechanical stability during reflow and resists moisture ingress better than conformal-coated chips in humid storage. Supplied on tape and reel for automated pick-and-place assembly.
