330 µF bulk decoupling — what the ESR and voltage rating mean for your rail
The TPSD337M010R0065: The 65 mOhm ESR is the figure that governs ripple current capability and output ripple voltage — a lower ESR means the capacitor can absorb more AC ripple without self-heating, which directly affects the derating calculation for a switching regulator output or a bulk decoupling bank. At 125°C the voltage derating recommendation is typically 50% for MnO2 tantalum — so a 10 V part should see no more than 5 V DC bias at that temperature to stay within the safe operating area.
Active lifecycle — still a current-production BOM line
The ±20% tolerance is standard for this capacitance value in the TPS series. For a bulk decoupling application where the exact capacitance is not critical, this tolerance is acceptable; for a timing or filter circuit, a tighter tolerance grade (if available in the same series) would be the better fit.
D-case 2917 footprint — board-fit and thermal considerations
This is the largest standard case size for the TPS series and carries the highest capacitance per footprint. The anode tab is on the short side; the cathode termination wraps around the ends. The PCB land pattern should follow the manufacturer's recommended footprint for the 7343 case to ensure adequate solder fillet and thermal relief. The molded case construction provides mechanical protection and consistent dimensions for pick-and-place assembly. The tape-and-reel packaging supports automated placement in volume production.
