The UBW1E471MPD is a radial-leaded aluminum electrolytic capacitor from Nichicon's UBW series, offering 470 µF capacitance at a 25 V rating. Designed for high-temperature, long-life operation, this polarized can-type capacitor is targeted at applications that require stable smoothing and energy storage in demanding thermal environments.

Key value propositions include a wide operating temperature range to +135°C, AEC-Q200 series qualification, and endurance characterized by a 2000-hour life at 135°C—providing designers with verifiable thermal endurance and industry-oriented qualification for automotive and other high-reliability markets.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 25 V DC rated voltage suitable for a variety of power applications.
• High-Temperature Endurance — Rated for operation from −55°C to +135°C with a specified lifetime of 2000 hours at 135°C.
• Ripple Current Performance — 737 mA at 120 Hz (low frequency) and 1.1 A at 10 kHz (high frequency), enabling effective ripple handling across common power frequencies.
• Low Impedance — 57 mΩ impedance supports lower loss and improved transient response in power circuits.
• Leakage Current — Specified leakage current of 352.5 µA.
• Mechanical & Mounting — Radial lead can package, size φ10 × 20L mm, lead spacing 5 mm; available in bulk (no terminal forming) or bag packing.
• AEC-Q200 Rating — Series-rated AEC-Q200 provides qualification relevant to automotive and other demanding industries.

Typical Applications

• Automotive electronic modules — Suitable for automotive systems where AEC-Q200 qualification and operation up to +135°C are required.
• High-temperature power electronics — Used where capacitor longevity at elevated ambient temperatures matters, backed by 2000 h endurance at 135°C.
• Long-life smoothing and decoupling — Provides bulk energy storage and ripple attenuation in designs requiring extended thermal endurance.

Unique Advantages

• Verified high-temperature life: 2000 hours at +135°C specification demonstrates endurance for prolonged high-temperature operation.
• Automotive-oriented qualification: AEC-Q200 rating supports use in applications where industry qualification is required.
• Strong ripple handling: Distinct low- and high-frequency ripple current ratings (737 mA at 120 Hz, 1.1 A at 10 kHz) give designers quantified performance across operating frequencies.
• Low ESR/impedance: 57 mΩ impedance reduces losses and improves transient response in power systems.
• Compact radial can package: φ10 × 20L with 5 mm lead spacing offers a small footprint for through-hole assemblies and bulk bag or bulk no-terminal-forming packing for flexible BOM/assembly choices.
• Clearly specified leakage: Leakage current defined at 352.5 µA for design margining and power budgeting.
