LGC2H271MELA50

The LGC2H271MELA50 is a Nichicon LGC series snap‑in terminal aluminum electrolytic capacitor designed for high‑voltage, long‑life applications. It provides 270 µF at 500 V in a compact φ25 × 50 mm can, delivering robust ripple handling and stable performance across a −40°C to 105°C operating range.

Engineered for general‑purpose power electronics where board‑space reduction and extended endurance are required, this capacitor combines a long 5000‑hour life rating at 105°C with RoHS compliance and tray packing for production use.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 500 V for high‑voltage energy storage and smoothing in power circuits.
• Snap‑In Terminal Package — Radial, can‑style snap‑in mounting for secure mechanical retention and straightforward PCB assembly.
• 105°C Long‑Life Endurance — Rated for 5000 hours at 105°C under DC bias plus rated ripple current, supporting extended operational life in demanding thermal environments.
• High Ripple Current Capability — Low‑frequency ripple current of 1.6 A at 120 Hz and high‑frequency ripple current of 2.288 A at 50 kHz, enabling effective ripple dissipation across a wide frequency range.
• Controlled Dissipation Factor — tan δ ≤ 0.25 (120 Hz, 20°C) for predictable AC loss behavior and stable impedance characteristics.
• Wide Temperature Range — Specified for operation from −40°C to 105°C to cover a broad range of industrial environments.
• Leakage Current Specified — Leakage current of 1100 µA to support predictable standby and no‑load conditions.
• Materials & Compliance — RoHS‑compliant construction and printed white marking on black sleeve for clear identification.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and DC link filtering where 500 V ratings and extended life are required for long‑running equipment.
• Power Conversion Modules — Energy storage and ripple suppression in high‑voltage inverters, converters and UPS modules.
• Motor Drives & Control — DC link and filtering applications in motor control systems that demand high ripple handling and thermal endurance.
• High‑Voltage Energy Storage — Applications that require compact, high‑voltage capacitors for transient energy buffering and discharge support.

Unique Advantages

• Compact high‑voltage form factor — Delivers 270 µF at 500 V in a φ25 × 50 mm can, enabling equipment downsizing where board space is constrained.
• Long life at elevated temperature — 5000‑hour rating at 105°C provides predictable aging and reduces maintenance or replacement frequency in continuous‑duty systems.
• Broad ripple performance — Specified ripple currents for both low and high frequencies help designers account for AC stress across common switching and line frequencies.
• Predictable electrical behavior — Defined tan δ, leakage current, and tolerance (±20%) support accurate circuit modeling and reliable power performance.
• Production‑ready packaging — Tray packing and mass‑production status simplify procurement and assembly for volume applications.
