UPJ1H471MHD

The UPJ1H471MHD is a radial-lead aluminum electrolytic capacitor from the Nichicon UPJ series designed for low-impedance, general-purpose power applications. It provides 470 µF capacitance at a 50 V rating in a compact 12.5 mm diameter × 25 mm length can with 5 mm lead spacing.

Engineered for switching power supplies and similar power-management tasks, this RoHS-compliant capacitor combines a wide operating temperature range (−55 °C to +105 °C) with a specified lifetime of 5000 hours at 105 °C for reliable long-term operation.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance at a 50 V rated voltage with ±20% tolerance, suitable for bulk energy storage and decoupling in power rails.
• Low Impedance Design — UPJ series low-impedance construction supports improved ripple handling and stable performance in switching power supply environments.
• High Temperature Endurance — Rated for operation from −55 °C to +105 °C with a load-life specification of 5000 hours at 105 °C, supporting sustained high-temperature use.
• Ripple Current Capability — Demonstrated ripple handling of 737.8 mA at 120 Hz and 1.19 A at 200 kHz, enabling effective smoothing under a range of operating frequencies.
• Radial Lead Package — 12.5 mm diameter × 25 mm length radial can with 5 mm lead spacing and polarized construction for through-hole PCB mounting.
• Leakage and Loss Characteristics — Meets the series leakage current specification (≤ 0.03CV µA after 1 minute at 20 °C) and tan δ limits defined for a 50 V rating (tan δ max. 0.10).
• RoHS Compliant — Conforms to RoHS directive requirements for environmental compliance.

Typical Applications

• Switching Power Supplies — Low impedance and specified ripple current make it suitable for output filtering and energy storage in SMPS designs.
• General-Purpose Power Filtering — Bulk decoupling and smoothing in a wide range of electronic equipment requiring robust, polarized electrolytic capacitors.
• Industrial Power Modules — Compact radial can and high-temperature endurance support use in industrial power subsystems operating up to 105 °C.
