UPA1E471MPD6

The UPA1E471MPD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPA series, designed for high-reliability power applications. It provides 470 µF of polarized capacitance at a 25 V rating in a compact φ10 × 12.5 mm can, optimized for low impedance and high ripple current handling.

Typical use cases include switching power supplies and general-purpose power smoothing where compact size, sustained ripple performance, and long operating life at elevated temperatures are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20%.
• Low Impedance — Rated impedance of 126 mΩ supports reduced voltage ripple in power rails.
• Loss Angle (tan δ) — tanδ = 0.14 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for design calculations.
• High Ripple Current Capability — Low-frequency ripple current 675 mA (120 Hz) and high-frequency ripple current 900 mA (10 kHz) for demanding switching environments.
• Reliability & Endurance — Rated for 4000 hours at 105°C, supporting long-term operation under elevated temperature and ripple stress.
• Temperature Range — Operational from −55°C to +105°C for broad environmental tolerance.
• Mechanical & Mounting — Radial lead, φ10 × 12.5 mm can (L = 12.5 mm, D = 10 mm), lead spacing 5.0 mm ± 0.5 mm; available as bulk (no terminal forming) or bag packing.
• Leakage Current — Specified leakage current 352.5 µA, useful for system power-loss and standby calculations.
• Compliance — RoHS compliant and in mass production.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where high ripple current capability and low impedance reduce voltage ripple on DC rails.
• Power Conversion Modules — Local energy storage and decoupling in compact converters and power modules requiring reliable decoupling at elevated temperatures.
• Industrial Control Electronics — Filtering and energy buffering in control boards that operate across −55°C to +105°C and require predictable endurance.
• Consumer Power Rails — General-purpose smoothing and decoupling for compact consumer devices where space-saving radial-lead components are preferred.

Unique Advantages

• Compact, high-capacitance package — 470 µF in a φ10 × 12.5 mm can reduces board area for designers constrained by space.
• Strong ripple-handling capability — 675 mA (120 Hz) and 900 mA (10 kHz) ripple ratings enable use directly on switching outputs and high-frequency decoupling points.
• Lower impedance for cleaner rails — 126 mΩ impedance helps minimize voltage droop and improves transient response on power lines.
• Extended high-temperature endurance — 4000 hours at 105°C provides predictable lifetime performance in thermally stressed applications.
• Radial-lead format for through-hole assembly — Simplifies prototyping and repair while fitting established PCBA assembly processes.
• Environmental compliance — RoHS compliance supports regulatory and sustainability requirements.
