LNT2G221MSECBN

The LNT2G221MSECBN is a Nichicon LNT-series screw-terminal aluminum electrolytic capacitor specified at 220 µF and 400 V. It is a polar, large-can radial package designed for general-purpose power applications where high-voltage smoothing, energy storage and robust terminal mounting are required.

This part offers a wide operating temperature range of −25°C to +105°C, a rated load life of 5,000 hours at 105°C, and RoHS compliance, providing predictable performance and long-term stability in industrial and commercial power systems.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 400 V rated voltage for mid- to high-voltage power systems.
• Endurance — Rated life of 5,000 hours at 105°C under rated ripple current, supporting sustained high-temperature operation.
• Ripple Current Capability — Low-frequency ripple current 1.6 A at 120 Hz and high-frequency ripple current 2.24 A at 100 kHz for effective smoothing across a range of switching and line frequencies.
• Leakage and Dissipation — Specified leakage current of 880 µA and tangent of loss angle (tan δ) of 0.2 measured at 20°C, 120 Hz for predictable loss characteristics.
• Temperature Range — Operating range from −25°C to +105°C (appropriate for the 400 V rated variant in the LNT series).
• Mechanical and Mounting — Radial, large-can package with screw terminals (φ35 × 80L) for secure electrical and mechanical connection in chassis- or bracket-mounted assemblies.
• Tolerance and Polarity — Capacitance tolerance −20% to +20%; polarized construction for correct DC applications.
• Packaging and Availability — Cardboard packing; product is in mass production and RoHS compliant.

Typical Applications

• General-purpose power filtering — Smoothing and decoupling in high-voltage DC bus and power supply stages where 400 V rating and 220 µF capacitance are required.
• Industrial power equipment — Bulk energy storage and ripple attenuation in industrial converters and power modules operating up to 105°C.
• Switching supplies and inverters — Handles both low-frequency and high-frequency ripple currents to stabilize DC rails in switched-mode converters.

Unique Advantages

• High-voltage capability: 400 V rating enables use in mid- to high-voltage power circuits without series stacking.
• Robust thermal endurance: 5,000 hours at 105°C supports long-term reliability in elevated-temperature installations.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 100 kHz address performance needs across both line-frequency and switching-frequency environments.
• Screw-terminal mounting: Large-can screw terminals provide secure, low-resistance connections suited to chassis and bracket mounting methods.
• Predictable electrical behavior: Defined tan δ (0.2) and leakage current (880 µA) measurements at 20°C give engineers clear parameters for thermal and loss budgeting.
• RoHS compliant and production-ready: Cardboard-packed, mass-production status simplifies procurement and assembly planning.
