UPA1E471MPD

The UPA1E471MPD is a Nichicon UPA series radial lead aluminum electrolytic capacitor offering 470 µF capacitance at a 25 V rating. It is a miniature, low-impedance electrolytic designed for general-purpose power applications, including switching power supplies where compact size and high ripple handling are needed.

With a wide operating temperature range of −55°C to 105°C, a 3000-hour endurance at 105°C, and RoHS compliance, this part is suited for designs that demand long-life performance in constrained board space.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 25 V and a capacitance tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 124 mΩ, supporting lower voltage ripple under load for better power stability.
• Loss Angle (tan δ) — tan δ = 0.14 measured at 20°C, 120 Hz, indicating dissipation characteristics for AC conditions.
• High Ripple Current Capability — Low-frequency ripple current of 645 mA (120 Hz) and high-frequency ripple current of 860 mA (10 kHz), enabling effective smoothing in switching supplies.
• Leakage Current — Specified leakage current of 352.5 µA after rated voltage application, for predictable standby and quiescent behavior.
• Endurance — Rated life of 3000 hours at 105°C (φ8 case), supporting long-term operation in elevated temperature environments.
• Compact Radial Package — Small footprint with dimensions φ8 × 15 mm, radial lead mounting and 3.5 mm lead spacing (±0.5 mm), for dense board layouts.
• Packaging & Availability — Available in bulk (no terminal forming) and bag packing; status: mass production. RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where compact, low-impedance capacitors reduce ripple and stabilize DC rails.
• Industrial Power Modules — Local energy storage and ripple smoothing in power converters and control modules operating up to 105°C.
• Consumer and Embedded Electronics — Decoupling and bulk capacitance in compact assemblies that require radial lead mounting and predictable leakage.
• Power Management Subsystems — Use in DC–DC converter outputs and intermediate bus filters benefiting from high ripple current capacity.

Unique Advantages

• Compact footprint with robust ripple handling: The φ8 × 15 mm radial can delivers 645 mA (120 Hz) / 860 mA (10 kHz) ripple current in a small package for space-constrained designs.
• Low impedance for improved regulation: 124 mΩ impedance helps reduce voltage drop under transient loads, improving power rail stability.
• Designed for elevated-temperature operation: 3000-hour endurance at 105°C provides predictable life performance in hot operating environments.
• Wide operating range: −55°C to 105°C supports deployments across a broad set of environmental conditions.
• Production-ready supply: Mass production status and standard packaging options (bulk / bag) simplify procurement and assembly planning.
• Standards compliance: RoHS compliance supports regulatory requirements for materials and environmental initiatives.

Why Choose UPA1E471MPD?

The UPA1E471MPD from Nichicon’s UPA series combines a compact radial can with low impedance and high ripple current capability, making it a practical choice for designers of switching power supplies and other power-management circuits that require reliable filtering in limited board space. Its 25 V rating and 470 µF capacitance provide substantial bulk energy storage while maintaining controlled dissipation (tan δ) and leakage characteristics.

Because it is offered in mass production with standard packaging options and a documented 3000-hour life at 105°C, the UPA1E471MPD is suited to teams focused on reproducible supply, predictable end-of-life behavior, and consistent field performance in general-purpose power applications.
