LGN2G271MELC25

The LGN2G271MELC25 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It combines a 400 V rated voltage with 270 µF capacitance in a compact φ35 × 25 mm can, offering high ripple tolerance and long life at elevated temperatures.

Engineered for robust performance, this capacitor delivers high low‑ and high‑frequency ripple current capability, low leakage, and a 3000‑hour endurance rating at 105°C, making it suitable for demanding industrial and power electronics designs that require stable bulk capacitance and reliable thermal endurance.

Key Features

• High Voltage & Capacitance — 270 µF nominal capacitance rated at 400 V for use where elevated DC bus or filter voltage is required.
• Snap‑In Radial Package — Snap‑in terminal, radial can (φ35 × 25 mm) form factor for secure board mounting and easy assembly; supplied in tray packing for production use.
• High Ripple Current Capability — Supports 1.22 A at 120 Hz (low frequency) and 1.745 A at 100 kHz (high frequency) to handle significant AC ripple and switching currents in power circuits.
• Low Leakage — Specified leakage current of 980 µA after rated voltage application, aiding in efficient DC performance and reduced self‑discharge.
• Long Endurance at Elevated Temperature — Rated for 3000 hours at 105°C under rated ripple conditions; meets endurance requirements after D.C. bias plus rated ripple current.
• Electrical Stability — Capacitance tolerance of ±20% and tangent of loss angle (tan δ) up to 0.15 (max.) at 120 Hz and 20°C, supporting predictable behavior in filtering and energy storage roles.
• Wide Operating Temperature Range — Operational from −25°C to +105°C for use across varied thermal environments.
• Regulatory Status — RoHS compliant, aligning with environmental restriction requirements.

Typical Applications

• High‑voltage power supplies — Bulk filtering and smoothing in equipment that requires a 400 V rated capacitor with substantial capacitance.
• Industrial power electronics — DC link and filter applications where high ripple current handling and thermal endurance at 105°C are required.
• Switching power converters — Energy buffering and ripple attenuation for converters and inverters operating with significant switching and AC ripple components.
• General‑purpose electronic equipment — Reliable bulk capacitance for a broad range of general‑purpose designs specified as such in the product data.

Unique Advantages

• High voltage capability: 400 V rating enables use in elevated DC bus and high‑voltage filtering applications without series stacking.
