UPS1C471MPD

The UPS1C471MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPS series designed for compact power applications. It is a radial lead, polarized capacitor with a nominal capacitance of 470 μF and a rated voltage of 16 V.

Engineered for switching power supplies and general-purpose power circuitry, this part delivers low impedance, elevated ripple current capability, and a wide operating temperature range for robust performance in constrained PCB layouts.

Key Features

• Capacitance & Rated Voltage — 470 μF nominal capacitance with a rated voltage of 16 V and a capacitance tolerance of -20%~20%.
• Low Impedance — Specified impedance of 190 mΩ to support stable decoupling and filtering in power circuits.
• Loss Angle (tan δ) — tanδ of 0.16 measured at 20°C, 120 Hz to characterize dissipation behavior.
• High Ripple Current Capability — Low-frequency ripple current of 426 mA at 120 Hz and high-frequency ripple current of 600 mA at 10 kHz for handling power supply ripple and switching noise.
• Leakage Current — Leakage current specified at 225.6 μA for predictable bias behavior.
• Endurance & Temperature Range — Rated for 2000 hours at 105°C with an operating temperature range of -55°C to 105°C.
• Compact Radial Package — Small can size φ10 × 12.5 mm and radial-lead mounting; lead spacing 5.0 mm with ±0.5 mm tolerance for through-hole assembly.
• Packaging Options & Production Status — Available in bulk (no terminal forming) or bag packing and currently in mass production.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Provides low-impedance bulk capacitance and ripple current handling for output filtering and energy storage in compact supply designs.
• General Power Filtering — Suited for smoothing and decoupling on DC rails where compact size and elevated temperature endurance are required.
• Industrial and Consumer Electronics — Useful in compact boards and modules that require reliable electrolytic capacitance across -55°C to 105°C.

Unique Advantages

• Space-saving footprint — φ10 × 12.5 mm can size and radial-lead package enable high-density PCB layouts without sacrificing capacitance.
• Designed for ripple-heavy environments — Specified ripple currents at both low and high frequencies (426 mA at 120 Hz, 600 mA at 10 kHz) support switching regulator outputs and high-frequency decoupling.
• Wide operating temperature range — Operation from -55°C to 105°C delivers stability across demanding thermal environments.
• Predictable electrical behavior — Low impedance (190 mΩ), defined tanδ (0.16), and specified leakage current (225.6 μA) make circuit performance easier to model and verify.
• Proven endurance at elevated temperature — Rated 2000 hours at 105°C for sustained reliability in thermally stressed applications.
• Regulatory compliance — RoHS compliance supports use in regulated product lines.
