LNY2G222MSEFBN

The LNY2G222MSEFBN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNY series, offering 2.2 mF (2200 µF) capacitance at a 400 V rating. It is a polarized, radial can-style capacitor designed for general-purpose power applications where high capacitance, high ripple handling and long operating life are required.

Designed for equipment downsizing and robust power filtering, this part delivers high low- and high-frequency ripple current capacity and a 2000-hour endurance at 85°C, making it suited to demanding commercial and industrial power systems operating between −40°C and 85°C.

Key Features

• High Rated Voltage: 400 V rated voltage suitable for medium-voltage power rails and bulk energy storage.
• Large Capacitance: 2.2 mF (2200 µF) nominal capacitance with ±20% tolerance (120 Hz, 20°C) for significant smoothing and energy buffering.
• High Ripple Current Handling: 9.6 A at 120 Hz (low frequency) and 13.44 A at 10 kHz (high frequency) to support high ripple environments and reduce heating under AC stress.
• Endurance and Temperature Range: Rated for 2000 hours at 85°C with an operating range of −40°C to 85°C for reliable performance in elevated-temperature installations.
• Leakage and Loss Characteristics: Specified leakage current of 2810 µA and a tangent of loss angle (tan δ) of 0.25 measured at 20°C and 120 Hz to aid predictable design margining.
• Screw Terminal Package: Radial can with screw terminals and M5 bolt compatibility for secure mechanical and electrical connections in chassis-mounted applications.
• Series-Level Design Benefits: LNY series features aimed at equipment downsizing and higher capacitance density while remaining RoHS compliant.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and filtering on 400 V rails, leveraging the 2200 µF capacitance and 9.6 A (120 Hz) ripple rating to stabilize DC outputs.
• Inverter and Motor Drive Systems: Energy buffering and DC-link support where high ripple current handling (13.44 A at 10 kHz) reduces thermal stress under switching loads.
• Commercial Power Electronics: General-purpose bulk capacitance in equipment that benefits from long endurance (2000 h at 85°C) and a wide operating temperature range (−40°C to 85°C).

Unique Advantages

• Robust High-Voltage Capability: 400 V rating enables use in medium-voltage DC systems without additional stacking or complexity.
• High AC Stress Tolerance: Dual ripple current specifications at 120 Hz and 10 kHz provide measurable guidance for thermal and lifetime budgeting in both line-frequency and switching environments.
• Durability at Elevated Temperatures: 2000-hour endurance at 85°C supports reliable operation in thermally challenging installations.
• Secure Screw-Terminal Mounting: Radial can with screw terminals and M5-compatible mounting simplifies installation and provides solid mechanical retention in chassis-mounted designs.
• Predictable Electrical Parameters: Specified tan δ and leakage current values allow accurate electrical margining during design and validation.
• RoHS Compliant: Material compliance supports regulatory requirements for commercial and industrial electronics.
