UEP1J471MHD

The UEP1J471MHD is a bi-polarized aluminum electrolytic capacitor from Nichicon’s UEP series designed for wide temperature operation and general-purpose use. It combines a 470 µF capacitance with a 63 V rating in a radial-lead can package, delivering stable performance over a broad environmental range for electronic designs that require bipolar operation.

Key Features

• Bi-Polar Construction Designed for bi-polar operation to support circuits where polarity may invert during use.
• Wide Temperature Range Rated for operation from −55°C to +105°C, enabling use across demanding environmental conditions.
• Capacitance and Voltage 470 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance for general-purpose energy storage and decoupling.
• Endurance and Reliability Specified for 1000 hours at 105°C with polarity inversion every 250 hours; capacitance change and leakage are defined after the endurance test.
• Loss and Leakage Characteristics Specified tan δ of 0.12 (max) at the 63 V rating and an expected leakage current of 888.3 µA (0.03 × C × V after 5 minutes at 20°C).
• Ripple Current Capability Rated ripple current: 680 mA at 120 Hz and 1.02 A at 10 kHz, with frequency coefficients defined in the datasheet for other frequencies.
• Radial Lead Can Package φ18 × 35.5 L can with radial leads, 7.5 mm lead spacing, suitable for through-hole mounting and hand or wave assembly processes.
• RoHS Compliant Conforms to RoHS directives for restricted substances.

Typical Applications

• General-purpose circuits — Useful where a bi-polarized aluminum electrolytic capacitor is required for power filtering or decoupling in mixed-polarity environments.
• Industrial electronics — Suitable for designs that require wide temperature operation and robust endurance at elevated temperatures.
• Electromechanical assemblies — Radial lead can package and 7.5 mm lead spacing support through-hole mounting in assemblies and retrofit applications.

Unique Advantages

• Bi-polar capability: Enables use in circuits with polarity reversal without requiring specialized polarity handling.
• Wide operating temperature: −55°C to +105°C rating helps maintain performance across extreme ambient conditions.
• Defined high-temperature endurance: 1000 hours at 105°C with polarity inversion every 250 hours provides a clear reliability baseline for thermal stress planning.
• Measured electrical characteristics: Low tan δ (0.12) and explicit leakage current (888.3 µA) make it straightforward to budget losses in power and timing analyses.
• Practical ripple handling: Ripple current ratings at 120 Hz and 10 kHz (680 mA and 1.02 A respectively) allow designers to match the part to expected operating frequencies.
• Through-hole packaging: Radial lead can with 7.5 mm spacing simplifies installation in traditional PCB layouts and prototyping fixtures.
