UPW1A471MPD

The UPW1A471MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series, designed for high-reliability power applications. It provides low impedance and robust ripple handling in a compact φ8 × 11.5 mm can with radial lead spacing of 3.5 mm.

With a rated voltage of 10 V, 470 µF capacitance, AEC-Q200 qualification and a wide operating temperature range of -55°C to 105°C, this part targets demanding power-conversion and embedded power-filtering designs where long endurance and stable performance are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a rated voltage of 10 V with tolerance ±20%.
• Low Impedance — Rated impedance of 234 mΩ, optimized for low-loss filtering and decoupling in power rails.
• Ripple Handling — Low-frequency ripple current 416.3 mA (120 Hz) and high-frequency ripple current 555 mA (10 kHz) to support switching supplies and DC–DC converters.
• Loss Tangent (tan δ) — tan δ of 0.19 measured at 20°C, 120 Hz (10 V rating), for predictable dissipation characteristics.
• Leakage Current — Leakage current specified at 141 µA, suitable for low-leakage power-storage requirements.
• High Reliability & Endurance — Life endurance of 3000 hours at 105°C; AEC-Q200 rating for regulated reliability requirements.
• Compact Radial Package — φ8 × 11.5 mm can, radial lead mounting with 3.5 mm lead spacing and bulk/bag packing options for production assembly.
• Wide Temperature Range — Operates from -55°C to 105°C to suit harsh thermal environments.

Typical Applications

• Switching Power Supplies — Local bulk and output filtering where low impedance and high ripple capability improve voltage regulation and transient response.
• DC–DC Converters — Input/output smoothing and energy storage for compact converter modules requiring high ripple endurance.
• Automotive Electronics — Power filtering and decoupling in automotive subsystems where AEC-Q200 qualification is required for reliability.
• Industrial Power Control — Filtering and smoothing in industrial controllers and sensors operating across wide temperature ranges.

Unique Advantages

• Compact footprint, high capacitance — 470 µF in a φ8 × 11.5 mm can minimizes board area while delivering substantial energy storage for localized power needs.
• Proven ripple performance — Specified LF and HF ripple currents (416.3 mA at 120 Hz, 555 mA at 10 kHz) enable reliable operation in switching environments without excessive heating.
• Robust thermal endurance — 3000 hours at 105°C provides long-term stability for designs exposed to elevated operating temperatures.
• AEC-Q200 rated — Qualification for regulated reliability applications supports use in demanding and safety-conscious systems.
• Predictable electrical loss — tan δ = 0.19 (20°C, 120 Hz) and specified impedance support accurate power-loss budgeting in thermal designs.
• Production-ready packaging — Available in bulk or bag packing to suit high-volume assembly and inventory workflows.
