220 µF, 10 V, 50 mOhm ESR — TPS series molded tantalum
The TPSE227M010R0050: The 50 mOhm ESR (equivalent series resistance) is the key parameter for power-supply decoupling and filtering applications — lower ESR means less self-heating and better ripple current handling at the switching frequency.
Temperature range and case code
Rated for -55°C to +125°C operation, this part covers the full industrial temperature envelope — suitable for equipment that sees both cold starts and sustained heat near the upper limit. Tolerance is ±20%, typical for tantalum electrolytics in bulk decoupling roles where the exact capacitance value is less critical than the ESR and voltage rating.
