UCS2W680MHD

The UCS2W680MHD is a miniature aluminum electrolytic capacitor from Nichicon's UCS series designed for high ripple current and long operating life. This radial-lead, polarized can is specified for 68 µF at 450 V and is intended for demanding power applications where high-voltage, high-ripple capability and extended endurance at elevated temperature are required.

Key use cases include power supplies and ballast applications; the part is RoHS compliant and rated for operation from −40°C to +105°C with a lifetime rating of 10,000 hours at +105°C.

Key Features

• High Voltage / Capacitance — 68 µF capacitance rated at 450 V, providing energy storage and filtering capability for high-voltage circuits.
• High Ripple Current Capability — Rated ripple currents of 787.5 mA at 120 Hz and 1.575 A at 100 kHz (105°C/100 kHz), supporting both low- and high-frequency ripple environments.
• Long Life at Elevated Temperature — Designed for 10,000 hours of operation at +105°C under rated conditions, with endurance specifications that include capacitance change within ±20% after life test.
• Wide Operating Temperature Range — Specified for −40°C to +105°C to cover a broad set of industrial and commercial operating environments.
• Through-Hole Radial Package — Radial lead, can-style package with 7.5 mm lead spacing and dimensions L: 3.05 × D: 1.8 cm for straightforward PCB mounting and mechanical robustness.
• Manufacturing and Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Standard Tolerance and Polarization — Capacitance tolerance of −20% to +20% and polarized construction for correct orientation in DC circuits.

Typical Applications

• Power Supplies — Bulk and filtering capacitor for high-voltage power conversion where 450 V rating and high ripple handling are required.
• Ballasts and Lamp Drivers — Suited for ballast applications that demand high-voltage operation and reliable ripple endurance.
• High-Frequency Switching Supplies — Supports high-frequency ripple currents up to 100 kHz, useful in switching regulator output or snubber networks.
• General-Purpose Industrial Electronics — Applies to general-purpose circuits that require robust, long-life electrolytic capacitance in a radial through-hole package.

Unique Advantages

• High ripple handling at both low and high frequencies: Specified ripple currents at 120 Hz and 100 kHz enable use across a range of switching frequencies.
• Extended operating life at elevated temperature: 10,000-hour rating at +105°C provides predictable endurance for long-term deployments.
• Compact, robust radial package: Small can dimensions (L: 3.05 × D: 1.8 cm) and 7.5 mm lead spacing simplify integration into through-hole assemblies.
• Wide temperature range: −40°C to +105°C rating supports diverse environmental conditions common in industrial applications.
• RoHS compliant: Meets current RoHS requirements for reduced hazardous substances.
