UCY2H330MHD

The UCY2H330MHD is a radial-lead aluminum electrolytic capacitor designed for high-voltage, high-ripple applications. It delivers 33 µF capacitance at a 500 V rating in a compact φ16 × 30.5 mm can with 7.5 mm lead spacing, combining high ripple capability and long-term endurance for demanding power applications.

This part is targeted at power supplies, ballast circuits and automotive electronic systems where AEC-Q200 qualification, extended lifetime and robust ripple handling are required.

Key Features

• Capacitance and Voltage — 33 µF capacitance rated at 500 V for high-voltage smoothing and energy storage in compact through-hole form.
• High Ripple Current — Rated ripple current up to 350 mA at 120 Hz and 700 mA at 100 kHz, enabling effective filtering under AC and high-frequency load conditions.
• Long Endurance — Designed for 10,000 hours of load life at +105°C (specified endurance for this size and voltage), supporting extended field service life.
• Thermal Range — Operating temperature range from −40°C to +105°C to cover a wide array of environmental conditions.
• Electrical Quality — Loss tangent (tanδ) 0.24 at 20°C/120 Hz and leakage current specified at 760 µA for controlled losses and predictable standby current.
• Robust Packaging and Mounting — Polarized radial-can package (φ16 × 30.5 mm) with 7.5 mm lead spacing (±0.5 mm) for through-hole assembly; available in bulk or bag packing.
• Automotive-Grade Reliability — AEC-Q200 qualified and RoHS compliant, addressing reliability and compliance requirements for automotive electronics.
• Frequency Response for Ripple Derating — Frequency coefficient of rated ripple current increases with frequency (1.00 at 120 Hz up to 2.00 at 100 kHz or more), allowing designers to scale ripple ratings for higher-frequency applications.

Typical Applications

• Automotive Power Electronics — Suitable for energy storage and filtering in automotive systems where AEC-Q200 qualification is required.
• Power Supplies — Suited for bulk filtering and ripple suppression in high-voltage power supply stages.
• Ballast Circuits — Intended for use in ballast applications requiring high-voltage capacitance and reliable long-term operation.

Unique Advantages

• High-voltage capability: 500 V rating lets designers reduce part count by using higher-voltage components where space and reliability matter.
• High ripple handling: Specified ripple currents at both low and high frequencies enable confident selection for AC, switching, and high-frequency power stages.
• Long life at elevated temperature: 10,000-hour endurance at +105°C supports extended deployment in thermally challenging environments.
• Automotive qualification: AEC-Q200 status provides an added layer of reliability assurance for vehicle electronics applications.
• Compact through-hole package: φ16 × 30.5 mm radial can with standard lead spacing simplifies installation in legacy and industrial boards.
