UCY2H100MHD

The UCY2H100MHD from Nichicon is a radial-leaded aluminum electrolytic capacitor rated 10 µF at 500 V. It is a miniature, high-ripple-current, long-life capacitor designed for demanding power applications.

Built for use in power supplies, ballast circuits and high-voltage systems, the UCY2H100MHD delivers high ripple-current capability, extended endurance at elevated temperature, and industry-recognized qualification for demanding environments.

Key Features

• High voltage rating — 500 V rated voltage suitable for high-voltage DC filtering and power conditioning.
• Compact radial package — φ12.5 × 20 mm can with radial leads and 5.0 mm lead spacing for straightforward through-hole mounting.
• Capacitance and tolerance — 10 µF with tolerance −20% to +20% at 120 Hz, 20°C.
• High ripple current capability — 160 mA at 120 Hz (low frequency) and 320 mA at 100 kHz (high frequency) to handle pulsed and AC components on DC rails.
• Electrical loss and leakage — tanδ (DF) 0.24 measured at 20°C, 120 Hz, and leakage current specified at 300 µA.
• Long endurance — Rated life of 10,000 hours at 105°C, designed for extended operation under elevated temperature and ripple stress.
• Wide operating temperature — −40°C to +105°C for broad environmental tolerance.
• Automotive-grade qualification — AEC-Q200 qualified and RoHS compliant for regulated and reliability-focused designs.
• Packaging options — Available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.

Typical Applications

• Power supplies — DC filtering and smoothing in high-voltage power conversion where 500 V capability and high ripple handling are required.
• Ballast circuits — Energy storage and ripple suppression in lighting ballast and similar high-voltage applications.
• Automotive electronics — Use in automotive power modules and high-voltage subsystems where AEC-Q200 qualification and extended temperature range are required.
• High-voltage DC systems — Local decoupling and bulk smoothing in medium- to high-voltage assemblies that demand long life at elevated temperature.

Unique Advantages

• High-voltage capability: 500 V rating enables use in applications that require elevated DC bus voltages without series stacking.
• Designed for ripple stress: Specified ripple currents at both low (160 mA at 120 Hz) and high (320 mA at 100 kHz) frequencies improve reliability under real-world switching loads.
• Extended life at high temperature: 10,000-hour endurance at 105°C reduces maintenance and replacement frequency in thermally demanding environments.
• Compact footprint: φ12.5 × 20 mm can with standard 5.0 mm lead spacing simplifies board-level integration for through-hole designs.
• AEC-Q200 qualified and RoHS compliant: Suits regulated and reliability-focused product programs, including automotive-grade designs.
