The UPW2C471MRD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW family, configured as a radial lead can. It delivers 470 µF capacitance at a 160 V rating with polarized construction, targeted for power-dense designs such as switching power supplies and automotive electronics.

Designed for sustained operation up to 105°C with a rated endurance of 8,000 hours at 105°C, this part offers high ripple-handling capability and low loss characteristics for robust power filtering and energy-storage roles in demanding environments.

Key Features

• Electrical — Capacitance & Voltage: 470 µF nominal capacitance with a rated voltage of 160 V and tolerance of −20% to +20%, suitable where high-voltage bulk capacitance is required.
• Low Loss & Dissipation: Tangent of loss angle (tanδ) = 0.15 measured at 20°C, 120 Hz, supporting efficient energy handling with predictable loss characteristics.
• Ripple Current Capability: Low-frequency ripple current 1.20 A (at 120 Hz) and high-frequency ripple current 1.38 A (at 10 kHz), allowing reliable performance across a range of switching frequencies.
• Long Endurance: Rated life of 8,000 hours at 105°C under DC bias plus ripple, enabling long-term stability in elevated temperature applications.
• Temperature Range: Operating range from −40°C to +105°C for operation across broad environmental conditions.
• Mechanical & Mounting: Radial lead can (φ22 × 50L) with 10 mm lead spacing (±0.5 mm), packaged in bulk / bag packing for straightforward through-hole assembly.
• Qualification: AEC‑Q200 rated, indicating suitability for applications requiring component-level reliability qualification.

Typical Applications

• Switching Power Supplies — Low-impedance, miniature construction supports output filtering and bulk capacitance in compact switch-mode supplies.
• Automotive Electronics — AEC‑Q200 rating and 8,000 h endurance at 105°C make this capacitor suitable for filtered power rails and energy storage in automotive systems.
• Space-Constrained Power Modules — Miniature-sized radial can (22 mm diameter × 50 mm length) provides high capacitance in compact through-hole layouts.

Unique Advantages

• High-Voltage Bulk Capacitance: 470 µF at 160 V supplies substantial energy storage for high-voltage rails while minimizing part count.
• Robust Ripple Handling: Specified ripple currents at both low and high frequencies support a wide range of switching frequencies and load conditions.
• Extended High-Temperature Life: 8,000 hours at 105°C under rated conditions delivers predictable aging and reduced maintenance in long-life systems.
• Automotive-Grade Qualification: AEC‑Q200 rating provides assurance for designs that require validated reliability workflows and component traceability.
• Compact Radial Package: φ22 × 50L radial can with standard 10 mm lead spacing eases integration into through-hole assemblies while conserving PCB area.
