LGW2G271MELA40

The LGW2G271MELA40 is a snap‑in terminal aluminum electrolytic capacitor offering 270 µF capacitance at a 400 V rating. Designed for general‑purpose electronic designs, it provides high ripple current capability and long‑term endurance under elevated temperature and ripple conditions.

This radial can, snap‑in package is specified for operation from −25 °C to +105 °C and is built to withstand 3,000 hours of rated ripple‑current application at 105 °C. The part is RoHS compliant.

Key Features

• Electrical Capacity — 270 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• High Voltage Rating — Rated voltage: 400 V for applications requiring elevated DC bus handling.
• High Ripple‑Current Performance — Specified ripple current: 1.83 A at 120 Hz and 2.617 A at 50 kHz; engineered for sustained ripple duty.
• Extended Endurance at Elevated Temperature — Guaranteed to withstand 3,000 hours of rated ripple current at 105 °C with capacitance change within ±20% and leakage current within initial specified limits.
• Thermal Range — Operating temperature range: −25 °C to +105 °C (400 V rating).
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20 °C (400–450 V range); leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20 °C.
• Package and Mounting — Radial, can snap‑in construction for secure chassis or PCB mounting in power assemblies; physical size approximately L: 4.0 cm × D: 2.5 cm.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic equipment — Suitable for designs that require a 400 V, 270 µF snap‑in electrolytic capacitor with high ripple capability and elevated temperature endurance.
• Power systems and assemblies — Used where sustained ripple current at 105 °C and long endurance are required.
• Repair, replacement and maintenance — Appropriate as a direct replacement choice when a 400 V snap‑in capacitor with comparable electrical and thermal ratings is specified.

Unique Advantages

• Designed for continuous ripple duty: Rated ripple currents (1.83 A at 120 Hz, 2.617 A at 50 kHz) and 3,000‑hour endurance at 105 °C reduce concern over ripple‑related degradation in demanding environments.
• High‑temperature reliability: Endurance testing criteria ensure capacitance, tan δ and leakage remain within specified limits after extended operation at 105 °C.
• Clear electrical limits: Leakage current defined by I ≤ 3√CV (µA) and tan δ ≤ 0.20 at 120 Hz (400 V range) provide predictable behavior for design calculations and quality checks.
• Robust mechanical mounting: Snap‑in radial can simplifies secure installation in chassis or assemblies where a through‑hole snap‑in termination is preferred.
• Regulatory compliance: RoHS compliance supports use in markets requiring restriction‑of‑hazardous‑substances conformance.
