UCY2W330MHD

The UCY2W330MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series, rated 33 µF at 450 V. It is a compact, polarized can-type capacitor designed for high-ripple, long-life operation in demanding power circuits.

Targeted at power-supply and ballast applications and qualified to AEC-Q200, this device delivers sustained performance across –40°C to +105°C with RoHS compliance for regulated designs.

Key Features

• Capacitance and Voltage: 33 µF rated at 450 V for high-voltage bulk and smoothing applications.
• High Ripple Current Capability: Rated ripple current of 400 mA at 120 Hz and 800 mA at 100 kHz, enabling effective handling of AC ripple across common switching frequencies.
• Long Operational Life: Load-life endurance of 12,000 hours at +105°C (endurance specifications include capacitance change within ±20%, tan δ within 200% of initial, and leakage current ≤ initial specified value).
• Temperature Range: Operates from –40°C to +105°C for wide-environment deployment.
• Compact Radial Package: Radial can with lead spacing of 5 mm and physical size L: 3.05 × D: 1.25 cm for space-constrained board designs.
• Automotive-Grade Qualification: AEC-Q200 qualified, supporting automotive and other high-reliability applications.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU) 2015/863).

Typical Applications

• Automotive Power Electronics: Energy-storage and smoothing in on-board power supplies and auxiliary converters where AEC-Q200 qualification is required.
• Power Supplies: Bulk filtering and ripple suppression in high-voltage DC power supplies and SMPS front-ends.
• Ballasts and Lamp Drivers: Designed specifically for ballast applications that demand high ripple tolerance and long life at elevated temperatures.

Unique Advantages

• Designed for High Ripple Environments: Explicit ripple ratings at 120 Hz and 100 kHz let designers select the capacitor with known AC stress capabilities.
• Proven Long-Life Endurance: 12,000-hour endurance at +105°C provides predictable aging characteristics for lifetime-sensitive designs.
• AEC-Q200 Qualification: Offers the documented reliability expectations required for automotive and similarly demanding applications.
• Wide Operating Temperature: –40°C to +105°C rating supports deployment across harsh thermal environments.
• Compact Radial Can Format: Small L × D footprint and 5 mm lead spacing simplify layout for high-voltage, space-constrained boards.
• RoHS Compliant: Meets common environmental regulation requirements for commercial and industrial products.
