LGN2G221MELB25

The LGN2G221MELB25 is a 220 µF, 400 V aluminum electrolytic capacitor in a snap‑in radial can designed for general‑purpose power applications. It’s a smaller‑sized member of Nichicon’s LGN series, optimized for installations that require high voltage handling, robust ripple endurance, and a compact board footprint.

Rated for operation from −25°C to 105°C and compliant with RoHS (2011/65/EU, (EU)2015/863), this part suits designs that need bulk energy storage and ripple suppression with long endurance at elevated temperature.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance at a 400 V rated voltage for high‑voltage smoothing and energy storage.
• High‑Temperature Endurance — Designed to withstand 3000 hours of rated ripple current application at 105°C, supporting sustained operation in elevated ambient conditions.
• Snap‑in Radial Can — Snap‑in mounting provides secure mechanical and electrical connection for power assemblies and simplifies PCB insertion.
• Compact, Smaller‑Sized Package — One rank smaller case than LGU series parts, enabling reduced board space for power modules and PSUs; physical dimensions L: 2.5 × D: 3.0 cm with a seated height max of 2.5 cm.
• Ripple Current Capability — Specified ripple current of 1.1 A at 120 Hz and 1.573 A at 100 kHz, suitable for filtering and smoothing in high‑ripple environments.
• Polarized, General‑Purpose — Polarized design with tolerance of −20% to +20%, intended for general‑purpose power applications.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk filtering and smoothing in high‑voltage supply rails where 400 V ratings and elevated temperature endurance are required.
• Power Conversion Modules — Energy storage and ripple suppression in rectifier, inverter and DC‑DC converter stages, leveraging the part’s specified ripple current handling.
• Motor Drives and Controllers — Decoupling and bulk capacitance for power rails in industrial motor control systems operating in warm environments.
• General Purpose High‑Voltage Electronics — Applications that require reliable, polarized electrolytic capacitance in a compact snap‑in can form factor.

Unique Advantages

• Long Endurance at Elevated Temperature — 3000‑hour rated ripple endurance at 105°C provides predictable lifetime behavior in thermally demanding systems.
• High Voltage and Bulk Capacitance — 400 V rating combined with 220 µF delivers substantial stored energy for smoothing and transient support in high‑voltage rails.
• Space‑Saving Package — One rank smaller case than comparable LGU parts reduces PCB area without sacrificing performance.
• Robust Ripple Handling — Explicit ripple current specifications at 120 Hz and 100 kHz allow designers to size capacitance to real application loads.
• Easy Assembly — Snap‑in mounting expedites insertion and secures the component for rugged power assemblies.
• Regulatory Compliance — RoHS compliance supports environmental and supply‑chain requirements.
