UPS1E472MHD

The UPS1E472MHD is a Nichicon UPS-series miniature aluminum electrolytic capacitor in a radial-lead can designed for power-filtering and energy-storage roles. It is a high-reliability type optimized for switching power supply and general-purpose power applications that require wide operating temperature and long endurance.

Key electrical characteristics include 4.7 mF capacitance at 25 V, low impedance (30 mΩ specified), rated ripple capability across low and high frequencies, and a qualified endurance of 3000 hours at 105°C.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) rated at 25 V, suitable for bulk energy storage and smoothing in DC power rails.
• Low Impedance — Specified impedance of 30 mΩ supports reduced output ripple and improved transient response.
• High Ripple Current Capability — Rated low-frequency ripple current of 2.349 A at 120 Hz and high-frequency ripple current of 2.7 A at 10 kHz for demanding switching supplies.
• Loss Characteristics — tan δ of 0.2 (measured at 20°C, 120 Hz) for predictable dissipation behavior in power applications.
• Reliability & Endurance — 3000 hours life at 105°C under rated conditions; leakage current specified at 3525 µA for this part.
• Wide Temperature Range — Operates from −55°C to +105°C for extended environmental range.
• Package & Mounting — Radial lead can, size φ18 × 35.5 mm (3.55 × 1.8 cm), 7.5 mm lead spacing; supplied in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and high ripple current capability reduce output ripple and improve regulation.
• General-Purpose Power Filtering — Energy storage and decoupling in power rails for industrial and electronic equipment that require wide temperature operation.
• Embedded Power Modules — Local energy reservoir in compact, radial-lead power modules and converters that benefit from a miniature can design.

Unique Advantages

• High Capacitance in a Compact Can — 4700 µF in a φ18 × 35.5 mm package reduces board space compared with multiple smaller capacitors.
• Designed for High Ripple Environments — Rated ripple currents at 120 Hz and 10 kHz support both low- and high-frequency switching topologies.
• Wide Operating Temperature and Long Life — −55°C to +105°C range and 3000 hours endurance at 105°C deliver predictable performance in elevated-temperature applications.
• Predictable Electrical Losses — Specified tan δ and impedance values simplify thermal and ripple loss budgeting in power designs.
• Production-Ready Availability — Product is in mass production and available in practical bulk or bag packing for volume assembly.
