LGW2W331MELC35

The LGW2W331MELC35 is a snap-in terminal aluminum electrolytic capacitor rated at 450 V with 330 µF capacitance. It is a polarized, radial can-style capacitor designed for general-purpose applications that require high ripple current handling and long-term endurance at elevated temperatures.

Key value propositions include high ripple current capability, endurance under continuous ripple at 105°C, and RoHS compliance—attributes aimed at designs where reliable power filtering and bulk energy storage at high voltage are required.

Key Features

• Rated Capacitance and Voltage — 330 µF capacitance at a 450 V rating for high-voltage bulk and filtering applications.
• High Ripple Current — Rated ripple current of 2.2 A at 120 Hz and 3.146 A at 50 kHz to support heavy AC ripple conditions.
• High-Temperature Endurance — Withstands 3000 hours application of rated ripple current at 105°C, meeting the endurance criteria described in the datasheet.
• Operating Temperature Range — Specified for operation from −25°C to +105°C to accommodate elevated ambient environments.
• Mechanical Package — Snap-in terminal, radial can package for secure PCB mounting and robust mechanical retention.
• Tolerance and Polarization — Capacitance tolerance ±20% and polarized construction as specified for electrolytic capacitors.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical size L: 3.5 × D: 3.5 cm for space-managed board layouts.

Typical Applications

• General-purpose power supplies — Bulk energy storage and smoothing where a 450 V rating and high ripple capability are required.
• Power conversion and inverters — Supports circuits with significant AC ripple and elevated operating temperatures due to its high ripple rating and 105°C endurance.
• Industrial equipment — Suitable for equipment that demands long-life capacitors with robust mounting and high-voltage handling.

Unique Advantages

• Designed for sustained ripple stress — Specified ripple current ratings and a 3000-hour endurance at 105°C mean longer service life under continuous ripple conditions.
• High-voltage capability — 450 V rating enables use in higher-voltage DC link and filtering applications without series stacking.
• Secure snap-in mounting — Radial snap-in can package provides mechanical stability for high-vibration or heavy-current assemblies.
• Predictable electrical characteristics — ±20% capacitance tolerance and defined leakage/tan δ expectations per the series datasheet support predictable design margins.
• Regulatory compliance — RoHS compliance simplifies environmental conformity in product development.
