The TPSD687M004R0060: The 60 mOhm ESR is the key figure for a bulk decoupling or hold-up cap: it governs ripple current capability and self-heating.
It uses a molded 2917 (7343 metric) surface-mount package, manufacturer size code D.
The equivalent series resistance is 60 mOhm. This ESR value determines ripple current handling and self-heating in bulk decoupling or filtering applications.
