UVK2W101MHD

The UVK2W101MHD is a Nichicon UVK series aluminum electrolytic capacitor in a miniature radial-can package. It delivers 100 µF capacitance at a 450 V rating with ±20% tolerance, designed for general-purpose high-voltage applications that require compact energy storage and smoothing.

Key electrical and reliability characteristics include low-frequency ripple current of 280 mA (120 Hz), high-frequency ripple current of 448 mA (10 kHz), a specified leakage current of 1900 µA, and an endurance rating of 2000 hours at 85°C. The part is RoHS compliant and supplied in bulk with no terminal forming.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance for high-voltage smoothing and energy storage.
• Ripple Handling — Rated ripple currents of 280 mA at 120 Hz and 448 mA at 10 kHz enable performance across low- and high-frequency power environments.
• Leakage Current — Specified leakage current of 1900 µA for predictable DC behavior after application of rated voltage.
• Thermal & Endurance — Operates from −25°C to 85°C with an endurance of 2000 hours at 85°C under rated voltage.
• Miniature Radial Can Package — φ18 × 40 mm can with 7.5 mm lead spacing and radial lead mounting; part of the UVK miniature sizing (one rank smaller case sizes than UVR).
• Polarized, Through-Hole Mounting — Polarized aluminum electrolytic with radial leads for through-hole assemblies; supplied in bulk/no terminal forming for mass production.
• RoHS Compliant — Manufactured in compliance with RoHS directives.

Typical Applications

• General-purpose power filtering — 450 V rating and 100 µF capacitance provide bulk smoothing and ripple reduction in high-voltage power supply rails.
• Energy storage for power electronics — Compact φ18×40 mm can supports constrained layouts where medium-term charge storage is required at elevated voltages.
• High-voltage DC link and decoupling — Dual-frequency ripple ratings (120 Hz and 10 kHz) make the capacitor suitable for decoupling across a range of switching and line-frequency conditions.

Unique Advantages

• High-voltage capability: 450 V rated voltage enables use in higher-voltage power rails while maintaining 100 µF capacitance.
• Miniature form factor: φ18 × 40 mm can and UVK series one-rank-smaller sizing reduce PCB footprint compared with larger radial cans.
• Dual-frequency ripple performance: Specified ripple currents at both 120 Hz and 10 kHz support a range of power-system frequencies and switching conditions.
• Designed for durability: 2000 hours endurance at 85°C under rated voltage supports sustained operation in elevated-temperature environments.
• Production-ready supply: Supplied in bulk with no terminal forming and listed as mass production status for volume assembly processes.
• Regulatory compliance: RoHS-compliant manufacturing supports restriction-of-hazardous-substance requirements.
