LGN2V221MELA30

The LGN2V221MELA30 is a snap-in terminal aluminum electrolytic capacitor rated at 350 V and 220 µF, designed for general-purpose power applications. It is a smaller-sized, snap-in radial can built for elevated-temperature operation and long-term ripple endurance.

Key value propositions include high-temperature endurance (designed to withstand 3000 hours of rated ripple current at 105°C), compact radial snap-in packaging, and RoHS compliance for environmentally conscious designs.

Key Features

• Electrical Core – 220 µF capacitance rated at 350 V with ±20% tolerance (−20% to +20%), polarized for DC applications.
• High-temperature Endurance – Specified to withstand 3000 hours of rated ripple current at 105°C, with post-test limits of capacitance change within ±20% and tan δ up to 200% of initial specification.
• Operating Range – Designed for operation from −25 °C to +105 °C for the 350 V class, suitable for elevated-temperature environments.
• Ripple Performance – Rated ripple current of 1 A at 120 Hz (low frequency) and 1.43 A at 100 kHz (high frequency), supporting common power-frequency and switching ripple conditions.
• Package & Mounting – Snap-in terminal, radial can snap-in package in a compact case (approximately L: 3 cm × D: 2.5 cm) with a maximum seated height of 1.181 inch, one rank smaller case size than LGU-series parts.
• Leakage and Dissipation Characteristics – Leakage current meets the series formula I ≤ 3/√C (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) conforms to series limits based on rated voltage.
• Environmental Compliance – Compliant to RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.

Typical Applications

• General-purpose power supplies – Bulk filtering and energy storage where a 350 V, 220 µF polarized snap-in capacitor with 105 °C endurance is required.
• Industrial power electronics – Applications that demand high-voltage smoothing in a compact snap-in package rated for extended ripple life at elevated temperatures.
• High-voltage DC bus decoupling – Use as a compact, high-voltage decoupling element in assemblies requiring reliable ripple handling and long-term stability.

Unique Advantages

• Compact high-voltage solution: One rank smaller case than LGU-series parts delivers space savings while maintaining 350 V capability.
• Proven high-temperature endurance: Rated for 3000 hours at 105 °C under rated ripple current, providing predictable life performance in hot environments.
• Dual-frequency ripple handling: Rated ripple current specified at both 120 Hz and 100 kHz to support power-frequency and switching applications.
• Robust electrical stability: Endurance and shelf-life specifications ensure capacitance and leakage remain within defined limits after thermal and electrical stress.
• RoHS compliant: Meets restricted substance directives for environmentally regulated projects.
