UBW1E221MPD

The UBW1E221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBW series, specified at 220 µF and 25 V with ±20% tolerance. It is designed for high-temperature, long-life use with an operating range of -55°C to +135°C and 2000 hours endurance at 135°C.

This compact can-style capacitor (φ10 × 12.5 mm) delivers low impedance (100 mΩ) and strong ripple handling—455.6 mA at 120 Hz and 680 mA at 10 kHz—making it suited for power filtering and energy smoothing in demanding environments.

Key Features

• Capacitance & Voltage: 220 µF rated at 25 V with ±20% tolerance for predictable bulk energy storage and decoupling.
• High-temperature endurance: Rated for operation from -55°C to +135°C with a 2000-hour endurance rating at 135°C.
• Low impedance: 100 mΩ impedance to support low-loss power delivery and improved transient response.
• Ripple current capability: 455.6 mA at 120 Hz (low frequency) and 680 mA at 10 kHz (high frequency) to handle AC stress in power circuits.
• Loss tangent (tan δ): 0.14 maximum at 20°C and 120 Hz, enabling predictable dissipation characteristics at rated conditions.
• Leakage current: Specified leakage current of 165 µA for predictable standby and bias behavior.
• Package & mounting: Radial lead can, size φ10 × 12.5L with 5 mm lead spacing (±0.5 mm); supplied in bulk or bag packing (no terminal forming).
• Qualification: AEC-Q200 rated, suitable for applications requiring recognized quality standards.

Typical Applications

• Automotive electronics: Power filtering and decoupling in automotive control modules and power systems where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC converters and power supplies: Bulk capacitance and ripple handling for voltage regulation and smoothing under continuous load.
• Motor control and drives: Energy buffering and suppression of voltage transients in motor inverter and drive circuits operating at elevated temperatures.
