UCY2H220MHD

The UCY2H220MHD is a radial-lead aluminum electrolytic capacitor designed for high-voltage power applications. It delivers 22 µF at a 500 V rating in a compact φ12.5 × 35.5 mm can with 5 mm lead spacing, combining high ripple handling and long-term endurance.

Engineered for power supplies, ballast applications and automotive electronics, this AEC-Q200 qualified and RoHS-compliant part provides long life at elevated temperatures—rated for 10,000 hours at 105°C—while maintaining controlled loss and low leakage for reliable DC filtering and energy storage.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance rated at 500 V for high-voltage filtering and energy storage.
• High Ripple Current — Rated ripple current of 280 mA at 120 Hz (low frequency) and 560 mA at 100 kHz (high frequency) to support demanding power circuits.
• Long Endurance — Life rating of 10,000 hours at 105°C under DC bias plus rated ripple current, providing sustained performance in hot operating environments.
• Low Loss & Leakage — Loss tangent (tanδ) of 0.24 (measured at 20°C, 120 Hz) and leakage current specified at 540 µA to minimize dissipation and standby drain.
• Robust Temperature Range — Operating from −40°C to +105°C to cover a wide range of environmental conditions.
• Compact Radial Package — φ12.5 × 35.5 mm can with 5.0 mm lead spacing (±0.5 mm) for through-hole assemblies; available in bulk or bag packing.
• AEC-Q200 Qualified & RoHS Compliant — Designed to meet automotive-grade qualification and environmental directives for regulated applications.
• Production Readiness — Listed as mass production status for reliable supply in volume designs.

Typical Applications

• Power Supplies — Bulk filtering and smoothing in high-voltage power supply rails where 500 V ratings and high ripple capability are required.
• Ballast Applications — Designed for ballast and similar high-voltage AC/DC applications that demand stable capacitance and long life at elevated temperatures.
• Automotive Electronics — Suitable for automotive power modules and high-voltage subsystems where AEC-Q200 qualification and extended temperature performance are important.

Unique Advantages

• High-voltage capability: 500 V rating lets designers use a single capacitor for higher-voltage rails, reducing part count.
• Strong ripple handling: Specified ripple currents at both low and high frequencies support a range of switching and line-frequency conditions.
• Extended high-temperature life: 10,000 hours at 105°C provides predictable longevity in elevated-temperature installations.
• Controlled dielectric loss and leakage: tanδ of 0.24 and leakage current of 540 µA help limit power dissipation and idle current draw.
• Automotive-grade and RoHS compliant: AEC-Q200 qualification and RoHS compliance help meet industry and regulatory requirements.
• Compact, through-hole form factor: φ12.5 × 35.5 mm radial can with 5 mm lead spacing for straightforward PCB mounting and mechanical stability.
