UPW1E471MPD

The UPW1E471MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series, designed for miniature, low-impedance power filtering. It provides 470 µF capacitance at a 25 V rating in a compact φ10 × 16L can, optimized for switching power supplies and automotive electronics.

Targeted at designs that require stable filtering, ripple handling and long-term endurance, this part combines low impedance, high ripple capability and AEC-Q200 qualification for demanding environments.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 25 V with tolerance −20% to +20% for predictable bulk energy storage and decoupling.
• Low impedance — Specified impedance of 136 mΩ, supporting improved transient response and reduced voltage drop on power rails.
• Loss angle (tan δ) — tanδ 0.14 measured at 20°C, 120 Hz, delivering controlled dissipation characteristics for power applications.
• Ripple current capability — Low-frequency ripple current 787.5 mA (120 Hz) and high-frequency ripple current 1.05 A (10 kHz) to handle DC–DC converter and switching supply ripple.
• Leakage current — Leakage current specified at 352.5 µA, minimizing quiescent loss when used on DC rails.
• High endurance — Rated for 5000 hours at 105°C, supporting long service life in elevated-temperature applications.
• Wide temperature range — Operating from −55°C to 105°C for use across harsh ambient conditions.
• Automotive-capable — AEC-Q200-rated and listed for Automotive applications where qualification is required.
• Package and mounting — Radial lead, can-type package with 5 mm lead spacing (±0.5 mm) and offered in Bulk (no terminal forming) and bag packing for production and prototyping workflows.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple handling reduce voltage ripple and improve regulator stability.
• Automotive Electronics — Power rail decoupling and energy storage in modules that require AEC-Q200 qualification and wide operating temperature range.
• DC Power Filtering — Smoothing and decoupling on DC–DC converters and power distribution networks benefitting from the capacitor’s endurance and leakage characteristics.

Unique Advantages

• Robust ripple handling: Rated ripple currents at both low (787.5 mA at 120 Hz) and high frequencies (1.05 A at 10 kHz) support a range of switching environments.
• Compact, low-impedance design: 136 mΩ impedance in a φ10 × 16L can reduces size without sacrificing transient performance.
• Long life at elevated temperature: 5000 hours endurance at 105°C provides predictable performance over extended field operation.
• Automotive-ready qualification: AEC-Q200 rating aligns the component to automotive electronics requirements where qualification is necessary.
• Wide operating range: −55°C to 105°C supports installations across harsh thermal environments.
• Practical packaging options: Bulk (no terminal forming) and bag packing accommodate production and prototype assembly processes.
