UPW1V471MPD

The UPW1V471MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for power-filtering use in switching power supplies and automotive electronics. It delivers 470 µF at 35 V with low impedance and rated endurance for extended operation at elevated temperature.

Sized at φ10 × 20 mm with 5 mm lead spacing, this radial-lead capacitor provides compact power decoupling and ripple handling where space and reliability are critical.

Key Features

• Electrical Performance — 470 µF nominal capacitance with ±20% tolerance and a rated voltage of 35 V, suited for DC power filtering and bulk decoupling.
• Low Impedance — Specified impedance of 104 mΩ; designed to reduce voltage ripple and improve transient response in switching supplies.
• High Ripple Current Capability — Rated ripple current of 915 mA at 120 Hz (low frequency) and 1.22 A at 10 kHz (high frequency) to support high-frequency switching environments.
• Leakage and Loss Characteristics — Leakage current value provided as 493.5 µA and tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz for predictable power loss behavior.
• High Temperature Endurance — Life rating of 5000 hours at 105°C, allowing sustained operation under elevated thermal stress.
• Mechanical & Packaging — Radial lead can (φ10 × 20L) with 5 mm lead spacing; available in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• Qualification — AEC-Q200 rating and explicit listing of Automotive in applications, supporting use in automotive electronics where that qualification is required.

Typical Applications

• Switching Power Supplies — Bulk decoupling and output filtering to reduce ripple and stabilize converters in switching power designs.
• Automotive Electronics — Power conditioning and smoothing in automotive control modules where AEC-Q200 qualification is specified.
• Power Modules and DC–DC Converters — Local energy storage and ripple attenuation for compact power conversion subassemblies.

Unique Advantages

• Reliable High-Temperature Operation: 5000-hour endurance at 105°C gives predictable life for thermal-stressed designs.
• High Ripple Handling: Dual-frequency ripple ratings (915 mA at 120 Hz, 1.22 A at 10 kHz) support both low- and high-frequency switching environments.
• Low-Impedance Design: 104 mΩ impedance helps reduce voltage drop and improve transient response in power rails.
• Automotive-Grade Qualification: AEC-Q200 rating provides qualification traceability for automotive applications that require this standard.
• Compact Radial Form Factor: φ10 × 20 mm can with 5 mm lead spacing delivers a small footprint for space-constrained power designs.
• Flexible Packaging Options: Available in bulk (no terminal forming) or bag packing to suit manual or automated assembly processes.
