LGNW6331MELA50

The LGNW6331MELA50 is a snap-in terminal type aluminum electrolytic capacitor designed for general purpose applications requiring high-voltage capability and sustained high-temperature operation. As a smaller-sized "snailer" in the LGN series, it delivers 330 µF at a 420 V rating with a compact snap-in radial can package and polarized termination.

Key value propositions include robust ripple-current handling, extended endurance at elevated temperatures, and RoHS compliance—features suited to through-hole power assemblies where reliable bulk capacitance and secure mounting are required.

Key Features

• Core Type & Mounting Aluminum electrolytic, polarized construction with snap-in radial can package for secure through-hole mounting.
• Capacitance & Voltage 330 µF nominal capacitance with a 420 V rated working voltage and ±20% capacitance tolerance (specified at 120 Hz, 20°C).
• Operating Temperature & Endurance Rated for operation from −25°C to +105°C and specified to withstand 3000 hours of rated ripple-current application at 105°C.
• Ripple Current Performance Rated ripple current: 1.42 A at 120 Hz and 2.031 A at 100 kHz, supporting sustained AC ripple stress under rated conditions.
• Compact Package Smaller-sized snailer design—one rank smaller case than LGU—with size dimensions of L: 5 × D: 2.5 cm for space-efficient layouts.
• Environmental Compliance Compliant with RoHS directives (2011/65/EU and (EU)2015/863).

Typical Applications

• General Purpose Power Circuits Bulk and smoothing capacitance in through-hole power assemblies where a polarized snap-in capacitor at 420 V is required.
• High-Temperature Environments Designs that demand stable capacitance and leakage performance at elevated ambient temperatures up to 105°C for extended periods.
• Through-Hole Power Modules Use in radial can form-factor PCBs and power modules that benefit from secure snap-in mounting and compact case size.

Unique Advantages

• Extended High‑Temperature Endurance: Specified for 3000 hours of rated ripple-current application at 105°C, providing predictable life under sustained thermal stress.
• High Voltage Capability: 420 V rating supports higher-voltage DC circuits without the need to parallel lower-voltage parts.
• Proven Ripple Handling: Defined ripple-current ratings at both 120 Hz (1.42 A) and 100 kHz (2.031 A) enable selection based on system frequency content.
• Space-Efficient Snap‑In Form Factor: One-rank-smaller case in the LGN family and compact dimensions (L: 5 × D: 2.5 cm) help optimize PCB real estate in through-hole designs.
• Regulatory Compliance: RoHS-compliant construction supports regulatory requirements for restricted substances.
