UCY2W101MHD

The UCY2W101MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series, delivering 100 µF capacitance at a 450 V rating. It is engineered for high ripple environments and extended operation at elevated temperatures, making it suitable for power electronics where sustained high-voltage performance and durability are required.

Designed for applications that demand high ripple current handling and long life, this polarized radial can combines compact dimensions (φ18 × 35.5 mm) with AEC-Q200 qualification and RoHS compliance.

Key Features

• Electrical Performance 100 µF capacitance with ±20% tolerance and a rated voltage of 450 V, suitable for high-voltage filter and energy-storage functions.
• High Ripple Current Capability Low-frequency ripple current 835 mA at 120 Hz and high-frequency ripple current 1.67 A at 100 kHz, supporting demanding AC ripple conditions.
• Loss and Leakage Characteristics Tangent of loss angle (tanδ) max 0.24 at 20°C, 120 Hz, and leakage current specified at 1900 µA for predictable performance under rated conditions.
• Long Endurance at Elevated Temperature Rated life of 12,000 hours at 105°C under DC bias plus rated ripple current, enabling long-term reliability in hot operating environments.
• Mechanical and Mounting Radial lead (polarized) package with 7.5 mm lead spacing (±0.5 mm) in a compact φ18 × 35.5 mm can for through-hole assemblies.
• Automotive-Grade and Compliance AEC-Q200 qualified and RoHS compliant, meeting quality and environmental requirements for regulated applications.
• Packaging Options Available in bulk (no terminal forming) or bag packing to support different assembly and procurement needs.

Typical Applications

• Automotive power electronics — Suited for high-voltage, high-ripple circuits in automotive systems where AEC-Q200 qualification is required.
• Power supplies — Used in AC-DC and DC-DC power supply filter stages and energy storage where 450 V rating and high ripple tolerance are needed.
• Ballast applications — Designed for ballast and related high-voltage power applications as identified in UCY series documentation.

Unique Advantages

• 450 V rating: Provides headroom for high-voltage filtering and energy storage in demanding power designs.
• High ripple/current handling: Dual-specified ripple currents (835 mA at 120 Hz and 1.67 A at 100 kHz) support both low- and high-frequency ripple environments.
• Extended high-temperature life: 12,000-hour endurance at 105°C assures longer service life in thermally challenging assemblies.
• AEC-Q200 qualification: Enables use in applications that require automotive-grade component reliability.
• Compact radial can: φ18 × 35.5 mm footprint with 7.5 mm lead spacing fits through-hole layouts while minimizing board space.
• RoHS compliant: Meets environmental regulatory requirements for lead-free designs.
