47 µF, 20 V, 200 mOhm ESR — the TPSD476M020R0200 in the TPS series
The 200 mOhm ESR is the key figure for filtering and decoupling applications — it sets the ripple current capability and the self-heating under AC load. A lower ESR means less power dissipated as heat for a given ripple current, which directly affects the capacitor's operating temperature and reliability in the circuit.
Temperature range and operating environment
This means the TPSD476M020R0200 can be used in engine-bay electronics, outdoor telecom gear, and industrial control systems that see wide thermal swings without derating the voltage or capacitance at the high end. The molded construction provides mechanical protection and moisture resistance suitable for conformal-coated assemblies.
