LGL2G102MELC50

The LGL2G102MELC50 is a snap-in terminal aluminum electrolytic capacitor rated at 1000 µF and 400 V, designed for general-purpose power electronic applications. Its snap-in, radial can package (φ35 × 50 mm) and tray packing support straightforward assembly into power modules and chassis-mounted equipment.

Key performance attributes include a –25°C to +105°C operating range, a rated ripple current capability, low dissipation factor, and a 2000-hour endurance at 105°C—making this part suitable where elevated temperature stability and bulk capacitance are required.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance at a rated voltage of 400 V, with capacitance tolerance ±20% (120 Hz, 20°C).
• Snap-in Radial Package — Radial, can-style snap-in package (φ35 × 50 mm) for secure mechanical mounting and easy installation in power assemblies.
• High Temperature Endurance — Rated for operation from –25°C to +105°C with an endurance specification of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Rated Ripple Current — 2.2 A at 120 Hz (and measured higher-frequency ripple capability of 3.146 A at 50 kHz), suitable for smoothing and decoupling under significant ripple loads.
• Leakage and Dissipation — Specified leakage current of 1.89 mA and tanδ (dissipation factor) of 0.15 at 120 Hz, 20°C (for 400 V rating), supporting predictable loss and self-heating behavior.
• Life and Reliability Data — Endurance and shelf-life characteristics per published test conditions: capacitance change within ±20%, tanδ ≤200% of initial spec, and leakage current ≤ initial specified value after endurance and shelf conditioning.
• Packaging & Production Status — Supplied in tray packing and currently in mass production for volume availability.

Typical Applications

• General-Purpose Power Electronics — Bulk smoothing and energy storage in designs that require 1000 µF at 400 V and robust temperature performance.
• Chassis or Module Power Assemblies — Snap-in radial can facilitates secure mechanical mounting and integration into power supply modules and enclosures.
• High-Temperature Environments — Use in systems that operate up to +105°C where sustained endurance (2000 h at 105°C) is required.

Unique Advantages

• High Voltage Capability: 400 V rating enables use in elevated-voltage circuits without series stacking.
• Large Bulk Capacitance: 1000 µF provides substantial energy storage and ripple smoothing in compact footprint (φ35 × 50 mm).
• Snap-in Mounting: Radial snap-in terminals simplify board or chassis assembly and offer reliable mechanical retention.
• Designed for Elevated Temperatures: Endurance specified at 105°C for 2000 hours helps ensure long-term stability in hot operating environments.
• Measured Ripple Performance: Rated ripple current of 2.2 A at 120 Hz (and demonstrated capability at higher frequencies) supports demanding AC ripple conditions.
• Controlled Losses and Leakage: tanδ of 0.15 and specified leakage current (1.89 mA) provide predictable dissipation and standby loss characteristics.
