The TPSD685K050R0600: The 600 mOhm ESR (equivalent series resistance) sets the self-heating under ripple current — for a given ripple, the power dissipated inside the part is I² × ESR, so the 600 mOhm figure limits how much AC current the capacitor can handle before the internal temperature rise exceeds the derating curve. The operating temperature range of -55°C to 125°C covers industrial and automotive ambient extremes; the 125°C ceiling is the maximum rated temperature, not a derated limit.
Surface-mount assembly with tape-and-reel packaging (Cut Tape also available) suits high-volume pick-and-place; the molded body provides consistent stand-off height for solder-joint inspection.
