LGU2C222MELC

The LGU2C222MELC is an aluminum electrolytic, snap-in terminal capacitor in Nichicon’s LGU series designed for general-purpose applications that require high capacitance and elevated voltage capability. With a 2.2 mF (2200 µF) capacitance at a 160 V rating and a polarized snap-in can package (φ35 × 45 mm), it delivers a combination of charge storage, ripple-current handling, and long-term endurance for demanding electronic designs.

Built to operate across a wide ambient range and withstand prolonged stress at high temperature, this part is targeted at applications where sustained performance at up to 105°C and robust ripple current capability are required.

Key Features

• Capacitance and Rated Voltage — 2.2 mF (2200 μF) with ±20% tolerance at a 160 V rating, providing substantial stored charge for high-voltage circuits.
• Snap-in Radial Can Package — Snap-in terminal type in a radial can format (φ35 × 45 mm) for secure board mounting and suitability for tray-based mass production.
• High Ripple Current Handling — Rated ripple current of 3.5 A at 120 Hz (low frequency) and 5.25 A at 50 kHz (high frequency) to support applications with significant AC ripple components.
• Leakage Current — Specified leakage current of 1770 μA, measured after application of rated voltage per standard test conditions.
• Wide Operating Temperature and Long Life — Operating range from −40°C to +105°C and endurance rated for 3000 hours at 105°C under rated ripple and DC bias conditions.
• Polarized — Designed as a polarized electrolytic capacitor for DC circuits.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• General Purpose (High-Voltage) — For designs needing 160 V rated voltage combined with 2.2 mF capacitance.
• General Purpose (High Ripple Current) — Suited to circuits that require 3.5 A ripple handling at 120 Hz and 5.25 A at 50 kHz.
• General Purpose (Elevated Temperature & Long Life) — Applicable where operation from −40°C to +105°C and 3000 hours endurance at 105°C are required.

Unique Advantages

• High-voltage energy storage: 2.2 mF at 160 V supplies significant stored charge for high-voltage DC applications.
• Robust ripple capability: Dual-specified ripple current ratings (low- and high-frequency) provide predictable thermal and electrical performance under AC stress.
• Long-term thermal endurance: 3000 hours at 105°C with defined post-test limits ensures reliable performance over extended high-temperature operation.
• Secure snap-in mounting: Snap-in terminal and radial can package support stable mechanical retention for production assemblies.
• RoHS compliant: Meets environmental directive requirements for lead-free applications.
