LNY2W822MSEHBB

The LNY2W822MSEHBB is an aluminum electrolytic, screw-terminal capacitor in Nichicon’s LNY series, offering 8.2 mF (8200 µF) capacitance at 450 V. Designed for general-purpose high-voltage bulk energy storage, it supports equipment downsizing while delivering sustained performance under ripple-loading conditions.

Key characteristics include a wide operating temperature range from −40 °C to +85 °C, a 2000-hour load life under rated ripple current at 85 °C, and RoHS compliance for environmental regulation adherence.

Key Features

• High Capacitance and Voltage: 8.2 mF (8200 µF) rated at 450 V for bulk energy storage and smoothing in high-voltage circuits.
• Screw Terminal Package: Radial can with screw terminals provides robust electrical and mechanical connections for panel- or bracket-mounted power assemblies.
• Temperature Range and Endurance: Operates from −40 °C to +85 °C with a specified endurance of 2000 hours at 85 °C when subjected to rated ripple current.
• Ripple Current Capability: Rated ripple current of 20.1 A at 120 Hz and 28.14 A at 10 kHz to support demanding AC ripple conditions.
• Leakage Current Specification: After 5 minutes at rated voltage and 20 °C, leakage current is not more than 3√(C·V) μA or 5 mA, whichever is smaller.
• Insulation and Voltage Proof: Insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute with no abnormality.
• Polarized Design with ±20% Tolerance: Polarized capacitor with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint for Downsizing: Physical footprint L: 17 cm × D: 7.62 cm in a radial can with screw terminals, specified to support equipment size reduction.

Typical Applications

• Power Conversion: Bulk smoothing and energy buffering in high-voltage power supplies and DC link circuits.
• Industrial Power Systems: Energy storage and ripple suppression where sustained ripple current capability and long endurance are required.
• Equipment Downsizing Projects: Use where high capacitance at elevated voltage enables reduction of overall system volume.

Unique Advantages

• High Voltage and Capacitance Combination: 8200 µF at 450 V provides substantial bulk energy storage without multiple parallel components.
• Designed for Ripple-Loaded Duty: Specified ripple current ratings at 120 Hz and 10 kHz and a 2000-hour endurance at 85 °C under ripple make it suitable for sustained AC ripple conditions.
• Robust Termination: Screw-terminal radial can construction ensures secure electrical connection and mechanical stability in mounted assemblies.
• Measured Reliability Metrics: Insulation resistance (>100 MΩ at DC 500 V) and voltage-proof (AC 2500 V, 1 min) test results support reliable operation in high-voltage assemblies.
• Regulatory Compliance: RoHS compliance supports use in designs requiring restricted-substance adherence.
