Bulk capacitance with a known ESR ceiling
The TPSE227M010R0100V is a 220 µF molded tantalum capacitor from the TPS series, rated at 10 V with ±20% tolerance. The 100 mOhm ESR at 100 kHz is the figure that governs ripple current handling and self-heating — a lower ESR means less internal temperature rise under AC load, which directly extends the 2000-hour lifetime at 125°C.
Temperature range and endurance
Operating from -55°C to 125°C, this part covers the full military temperature band. The 2000-hour lifetime at 125°C is the rated endurance under continuous bias — in a 85°C ambient, the expected life increases significantly per the Arrhenius acceleration typical for tantalum dielectrics.
