UPW1C471MPD

The UPW1C471MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW series. It is a radial-lead, polarized electrolytic designed for low impedance and sustained performance in demanding environments.

Targeted for switching power supplies and automotive applications, this part combines a 470 µF capacitance at 16 V with a compact φ10 × 12.5 mm can, AEC-Q200 rating, and a -55 °C to 105 °C operating range to support long-life power-filtering and bulk energy storage requirements.

Key Features

• Electrical — 470 µF, 16 V: Provides 470 µF nominal capacitance with a rated voltage of 16 V and a tolerance of -20% to +20%.
• Low impedance: Specified impedance of 180 mΩ supports lower ripple voltage in power rails.
• Ripple handling: Low-frequency ripple current of 570 mA (120 Hz) and high-frequency ripple current of 760 mA indicate robust ripple capability for switching environments.
• Loss characteristics: tanδ (DF) of 0.16 measured at 20 °C, 120 Hz for dielectric loss assessment.
• Leakage current: Specified leakage current of 225.6 µA after rated voltage application at 20 °C.
• High-temperature endurance: Rated for 5,000 hours at 105 °C, supporting long-term operation under elevated temperature conditions.
• Package & mounting: Radial lead, can-style package with 5 mm lead spacing and lead spacing tolerance ±0.5 mm; available in bulk (no terminal forming) or bag packing.
• Compact dimensions: Body diameter φ10 mm and length 12.5 mm (height seated max 1.25 cm) for space-constrained through-hole designs.
• Qualification: AEC-Q200 rated to support use in applications requiring that qualification.

Typical Applications

• Switching Power Supplies — Low impedance and specified ripple current ratings make this capacitor suitable for output filtering and energy storage in switching regulators.
• Automotive Electronic Modules — AEC-Q200 rating and 5,000-hour endurance at 105 °C enable use in automotive power systems and control modules.
• High-Reliability Power Rails — Compact radial form factor and low-loss characteristics suit bulk decoupling and smoothing on regulated DC rails in embedded systems.

Unique Advantages

• Compact, space-saving can: φ10 × 12.5 mm body provides 470 µF capacitance in a small through-hole package to save board area.
• Low impedance for reduced ripple: 180 mΩ impedance helps minimize ripple voltage, improving regulator stability and transient response.
• High ripple capability: Defined low- and high-frequency ripple current ratings (570 mA at 120 Hz, 760 mA at 10 kHz) support switching environments across frequency ranges.
• Long elevated-temperature life: 5,000 hours at 105 °C gives predictable lifetime performance for designs exposed to sustained high temperatures.
• AEC-Q200 qualification: Meets AEC-Q200 rating for customers requiring that qualification for automotive or similarly demanding use cases.
• Flexible packing options: Available in bulk (no terminal forming) or bag packing to match assembly and inventory workflows.
