UCS2E220MPD

The UCS2E220MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UCS series, designed for miniature, high-ripple-current applications. It combines a compact φ10×20 mm can with robust electrical performance for general-purpose power filtering and ballast or power-supply circuits.

Key value propositions include high ripple-current capability across low and high frequencies, long operational life at elevated temperature, and a wide operating temperature range suitable for demanding industrial and commercial electronics.

Key Features

• Capacitance and Voltage: 22 µF nominal capacitance with a 250 V rated voltage and capacitance tolerance of −20% to +20%.
• Low-loss dielectric: tanδ (DF) of 0.20 measured at 20°C, 120 Hz, indicating controlled dissipation for stable AC performance.
• High ripple-current capability: Rated ripple current of 250 mA at 120 Hz (low frequency) and 500 mA at 100 kHz (high frequency), suited for smoothing and decoupling under ripple-loading conditions.
• Leakage current: Specified leakage current of 320 µA (after 1 minute at 20°C), supporting low self-discharge in biased circuits.
• Long endurance: Designed for 8,000 hours of life at +105°C for the φ10×20 mm case size.
• Compact radial package: φ10×20 mm can with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting—bulk (no terminal forming) or bag packing available.
• Wide operating temperature: Usable from −40°C to +105°C for a broad range of environmental conditions.
• RoHS compliant: Manufactured in compliance with RoHS requirements.

Typical Applications

• Power supplies: Smoothing and bulk decoupling in linear and switching power supplies where high ripple current and compact size are required.
• Ballasts and lighting circuits: Filtering and energy storage in ballast designs as noted for the UCS series.
• General-purpose electronics: EMI filtering, decoupling and energy storage in compact industrial and commercial equipment.

Unique Advantages

• High ripple-handling in a miniature can: 500 mA at 100 kHz and 250 mA at 120 Hz delivered from a φ10×20 mm package reduces board space without sacrificing ripple capability.
• Long life at elevated temperature: Rated for 8,000 hours at 105°C for the 10×20 case, enabling longer maintenance intervals in thermally stressed designs.
• Controlled dissipation factor: tanδ of 0.20 (20°C, 120 Hz) supports predictable AC performance and thermal behavior under ripple load.
• Low leakage: 320 µA leakage current specification helps minimize bias loss and stabilizes circuit behavior after power application.
• Compact radial form factor: φ10×20 mm can with 5 mm lead spacing fits tight layouts while providing conventional through-hole mounting reliability.
• Regulatory compliance: RoHS-compliant construction supports use in regulated product lines.
