UPW1E472MHD

The UPW1E472MHD is a radial-lead aluminum electrolytic capacitor in the Nichicon UPW series, offering 4.7 mF (4700 µF) capacitance at a 25 V rating. Designed as a miniature, low-impedance, high-reliability solution for power conversion, it is built for switching power supplies and other demanding power applications.

This part combines high ripple-current capability, extended high-temperature endurance and a compact radial can package (φ18 × 35.5 mm), making it suitable for systems where long life and robust power handling are required.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance with a rated voltage of 25 V and tolerance ±20%.
• Low Impedance — Rated impedance of 30 mΩ, supporting lower voltage drop under ripple and transient conditions.
• High Ripple Current Handling — Low-frequency ripple current 3.128 A (120 Hz) and high-frequency ripple current 3.68 A (10 kHz) to support switching regulator and decoupling applications.
• Endurance at Elevated Temperature — Life rating of 8000 hours at 105°C for sustained high-temperature operation.
• Wide Operating Temperature — Specified for −55°C to +105°C operation to cover harsh environmental conditions.
• Physical & Mounting — Radial, can-style package with dimensions φ18 × 35.5 mm (L: 3.55 × D: 1.8 cm), lead spacing 7.5 mm (±0.5 mm), and bulk/bag packing options.
• Electrical Losses — Dissipation factor (tan δ) 0.2 at 20°C, 120 Hz, indicating specified dielectric loss characteristics for the 25 V rating.
• Leakage Current — Specified leakage current 3525 µA under product test conditions.
• Qualification — Rated with AEC-Q200, supporting designs that call for recognized reliability screening.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where low impedance and high ripple current capability improve regulator stability and efficiency.
• Automotive Electronics — Suitable for automotive systems that require AEC-Q200-rated parts and operation across −55°C to +105°C.
• High-Temperature Power Modules — For power assemblies that demand long endurance at elevated temperatures (8000 hours at 105°C).

Unique Advantages

• Designed for high ripple environments: Supports 3.128 A at 120 Hz and 3.68 A at 10 kHz, enabling reliable filtering in switching circuits.
• Low impedance performance: 30 mΩ impedance reduces losses and voltage ripple under load, benefiting regulator performance.
• Long life at elevated temperature: 8000-hour endurance at 105°C provides predictable lifetime in thermally stressed designs.
• Automotive-grade qualification: AEC-Q200 rating aligns the component with automotive reliability requirements where specified.
• Compact radial can package: φ18 × 35.5 mm size with 7.5 mm lead spacing offers a space-efficient solution for through-hole assemblies.
