UPA1E472MHD

The UPA1E472MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UPA series. It delivers low impedance and high ripple-current capability in a compact radial-can package, intended for demanding general-purpose power applications.

Designed for use in switching power supplies and other power-filtering roles, this polarized radial-lead capacitor provides a balance of capacitance (4.7 mF), rated voltage (25 V), and robust thermal endurance for reliable performance across a wide operating temperature range.

Key Features

• Capacitance & Voltage — 4.7 mF capacitance at a 25 V rated voltage, suitable for bulk decoupling and energy storage in low-voltage power rails.
• Low Impedance — Rated impedance of 36 mΩ, supporting improved transient response and reduced voltage ripple under load.
• High Ripple Current Capability — Handles 2.422 A at 120 Hz and 2.85 A at 10 kHz, enabling reliable smoothing in switched-mode power supplies and converters.
• Temperature & Lifetime — Operational range of −55°C to +105°C with a guaranteed endurance of 5000 hours at 105°C, for long-term high-temperature reliability.
• Package & Mounting — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (L: 2.5 × D: 1.8 cm), simplifying board layout for space-constrained designs.
• Polarized Electrolytic — Standard polarized construction for typical DC power applications; capacitance tolerance ±20%.
• RoHS Compliant — Conforms to RoHS environmental requirements.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current make the UPA1E472MHD suitable for output filtering and energy buffering in switch-mode converters.
• General-Purpose Power Filtering — Bulk decoupling and smoothing on DC rails where compact size and reliable ripple handling are required.
• Power Supply Decoupling — Local decoupling at regulator outputs or intermediate power nodes to improve transient response and stability.

Unique Advantages

• Compact, high-capacitance form — 4.7 mF in a miniature radial-can package reduces board area while providing substantial energy storage.
