UHE1E471MPD

The UHE1E471MPD is a high-performance Aluminum Electrolytic Capacitors designed for demanding applications. Its 470uF capacitance and 25V voltage rating make it ideal for switch-mode power supplies, industrial inverters, motor drives, and automotive electronics. The capacitor's high ripple current capability and long lifetime ensure reliable operation in continuous-duty applications. It is particularly well-suited for DC-link filtering, energy storage, and smoothing applications where high capacitance density and reliability are critical.

Consider UHE1E471MPD for your power electronics designs requiring high capacitance and voltage ratings. Contact our FAE team for application-specific recommendations.

The UHE1E471MPD features an impressive rated lifetime of 10,000 to 15,000 hours at rated temperature (105°C). Using the Arrhenius equation, we can estimate that every 10°C reduction in operating temperature approximately doubles the capacitor lifetime. Therefore, at 65°C ambient temperature, the expected lifetime extends to 80,000-120,000 hours (9-14 years) of continuous operation. This exceptional longevity makes it ideal for industrial and automotive applications where maintenance-free operation is essential.

For maximum reliability with UHE1E471MPD, we recommend the following derating practices: 1) Voltage derating: Operate at 80% or less of rated voltage (derate to 20V or lower), 2) Temperature derating: Keep operating temperature at least 10-20°C below maximum rated temperature, 3) Ripple current: For continuous operation, limit ripple current to 70-80% of rated value, 4) Avoid rapid temperature cycling which can stress the capacitor, 5) Consider parallel configurations for high-ripple applications to distribute current. These derating practices can extend capacitor lifetime by 2-4x compared to operating at maximum ratings.
