LGW2G331MELC30

The LGW2G331MELC30 is a snap‑in terminal type aluminum electrolytic capacitor designed for general‑purpose power applications that require high ripple current handling and elevated temperature endurance. It provides 330 µF capacitance at a 400 V rating, polarized construction, and RoHS compliance.

Engineered for sustained operation in warm environments, this capacitor withstands rated ripple current for 3000 hours at 105°C, making it suitable where long endurance under continuous ripple stress is required.

Key Features

• Capacitance & Voltage — 330 µF capacitance rated at 400 V for high‑voltage DC filtering and energy storage in general‑purpose equipment.
• High Ripple Current — Rated ripple current of 2.33 A at 120 Hz (low frequency) and 3.332 A at 50 kHz (high frequency), with frequency coefficients for ripple current specified in the series datasheet.
• 105°C Endurance — Demonstrated endurance of 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current, with post‑test limits defined for capacitance, tan δ and leakage current.
• Operating Temperature Range — −25°C to +105°C operating temperature suitable for elevated ambient conditions specified for the 400 V class.
• Snap‑In Radial Package — Snap‑in terminal, radial can package for secure PCB mounting and mechanical stability in power assemblies; maximum seated height 1.181 inch.
• Leakage Current Specification — Meets the datasheet leakage current criterion: I ≤ 3√CV (µA) after 5 minutes' application of rated voltage at 20°C.
• Polarized Design — Polar capacitor intended for DC applications; capacitance tolerance ±20% at 120 Hz, 20°C.
• Environmental Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk smoothing and ripple attenuation on 400 V DC rails in general‑purpose power supplies and industrial equipment.
• Power conversion — Energy storage and ripple management in converters and inrush‑susceptible circuits where high ripple current and elevated temperature endurance are required.
• Industrial electronics — Use in control and power modules that operate at elevated temperatures up to 105°C and demand long ripple‑current lifetime.

Unique Advantages

• Long ripple‑current endurance: Rated to withstand 3000 hours of rated ripple current at 105°C, supporting designs that require sustained high‑stress operation.
• High voltage and capacitance combination: 330 µF at 400 V provides substantial energy storage and filtering capability in a compact radial snap‑in can.
• Frequency‑aware ripple performance: Ripple current ratings include frequency behavior (datasheet coefficients), enabling more accurate thermal and ripple budgeting across operating frequencies.
• Secure snap‑in mounting: Snap‑in terminals offer robust mechanical retention for power PCBs and ease of assembly in through‑hole layouts.
• RoHS compliant: Meets current RoHS directives for environmental and regulatory compatibility.
