Active production — what it means for a BOM line
The TPSD475K050Y0700: A design-in decision today does not carry an imminent migration risk.
4.7 µF at 50 V — the capacitance-voltage intersection
4.7 µF capacitance at a 50 V rated voltage in a D-case (2917 / 7343 metric) footprint. This is the capacitance-voltage product that fits a bulk decoupling or small DC-link position on a 24 V or 48 V rail where the steady-state voltage stays under 50 V with margin. The 700 mOhm ESR governs the ripple current the part can carry before self-heating becomes the limiting factor — at 100 kHz, the impedance is dominated by this ESR, not the capacitive reactance.
Temperature grade and board-fit
The molded epoxy case is the standard surface-mount construction — no hermetic seal, no conformal coating.
