LGN2H271MELC40

The LGN2H271MELC40 is an aluminum electrolytic, snap‑in terminal capacitor designed for general-purpose high‑voltage applications. It delivers 270 µF at a 500 V rating in a compact, smaller-sized "snailer" case for applications that require high ripple endurance and elevated temperature operation.

Key value comes from its 105 °C endurance — specified for 3000 hours under rated ripple current — plus high ripple capability up to 1.602 A at 100 kHz, making it suitable where sustained high-voltage smoothing and stability are required.

Key Features

• Core Type: Aluminum electrolytic capacitor — polarized design providing 270 µF nominal capacitance with ±20% tolerance.
• High Voltage Rating: 500 V rated voltage for applications requiring elevated DC voltage handling.
• High‑Temperature Endurance: Rated to operate from −25 °C to 105 °C (appropriate for 350–600 V parts) with endurance specified as 3000 hours at 105 °C under rated ripple current.
• Ripple Current Capability: Designed for high ripple environments with 1.12 A at 120 Hz and 1.602 A at 100 kHz ripple current ratings.
• Compact Snap‑In Package: Radial can, snap‑in mounting for robust board retention and straightforward assembly; one rank smaller case size than LGU series.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power modules: Provides bulk smoothing and energy storage where a 500 V rating and high ripple endurance are required.
• Industrial power electronics: Suited to assemblies that operate at elevated temperatures up to 105 °C and demand sustained ripple capability.
• General-purpose DC filtering: Ideal for circuits needing polarized, high-capacitance components in a compact snap‑in form factor.

Unique Advantages

• High‑voltage, high‑capacitance combination: 270 µF at 500 V delivers significant energy storage for demanding DC applications.
• Proven high‑temperature reliability: Endurance specified for 3000 hours at 105 °C under rated ripple current supports long-term operation in hot environments.
• Wide ripple‑frequency support: Ripple ratings given at both 120 Hz and 100 kHz allow designers to account for low- and high-frequency ripple conditions.
• Space‑efficient snailer form: One rank smaller case than the LGU series reduces board space without sacrificing voltage or ripple performance.
• Secure, assembly‑friendly mounting: Snap‑in radial can simplifies mechanical retention and PCB assembly for high-voltage modules.
• Regulatory compliance: RoHS conformity ensures alignment with common environmental requirements.
