Capacitance, voltage rating, and ESR — the decoupling decision
The TPSD685K050A0600 is a 6.8 µF tantalum capacitor rated at 50 V with ±10% tolerance. The 600 mOhm ESR at 100 kHz governs ripple current handling and self-heating — for a 50 V rail bulk decoupling, the ESR limits the ripple current to a level that keeps the part within its thermal envelope at 125°C.
Temperature endurance and operating range
This endurance and temperature grade suits power-supply hold-up and filtering circuits in industrial or telecom equipment where the ambient temperature near the capacitor stays below the rated ceiling.
Package and footprint — 2917 molded case
The molded case provides mechanical stability during reflow; the tape-and-reel packaging supports automated pick-and-place.
