LGW2E331MELA25

The LGW2E331MELA25 is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LGW series designed for general‑purpose applications that require high ripple current handling and robust thermal endurance. It provides 330 µF capacitance at a 250 V rating in a radial can snap‑in package, suited to equipment where reliable bulk capacitance and long life at elevated temperatures are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance for predictable energy storage in high‑voltage circuits.
• High Ripple Current & Endurance — Rated for high ripple current with specified values of 1.8 A at 120 Hz and 2.7 A at 50 kHz, and designed to withstand rated ripple current for 3000 hours at 105°C.
• Operating Temperature Range — Specified for operation from –40°C to +105°C to support equipment exposed to wide ambient conditions.
• Snap‑In Radial Package — Snap‑in terminal, radial can construction for secure board mounting and mechanical stability in power assemblies.
• Leakage Current Specification — Meets the series leakage current requirement I ≤ 3√(C·V) μA after 5 minutes’ application of rated voltage at 20°C.
• Polarized Design — Polarized aluminum electrolytic format for DC applications where correct polarity is maintained.
• RoHS Compliant — Manufactured to meet RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Provides bulk capacitance and smoothing at 250 V for general‑purpose power supply designs that require high ripple current handling.
• DC link and energy storage — Serves as DC link or energy reservoir in power conversion circuits where 330 µF at 250 V is required.
• Industrial electronics — Suitable for general‑purpose industrial equipment operating across –40°C to +105°C that needs long‑life capacitors with high ripple endurance.

Unique Advantages

• High ripple endurance: Rated ripple current values and a 3000‑hour endurance at 105°C under rated ripple current provide predictable life under sustained AC stress.
• Wide thermal range: –40°C to +105°C operation supports designs exposed to varying ambient temperatures without derating beyond specified limits.
• Robust snap‑in mounting: Snap‑in terminals in a radial can provide secure mechanical retention for power PCBs and ease of assembly.
• Clear electrical limits: Specified leakage current and capacitance tolerance (±20%) enable accurate circuit design and margining for power applications.
• Regulatory compliance: RoHS compliance aligns the component with restricted substances requirements for global markets.
