LNY2W392MSEHBB

The LNY2W392MSEHBB is an aluminum electrolytic capacitor in a screw-terminal radial can package, offering 3.9 mF (3900 µF) capacitance at a 450 V rating. It is designed for general-purpose equipment where high capacitance, secure screw-terminal connections, and compact sizing are required.

Key characteristics include an operating temperature range of −40°C to +85°C, a rated load life of 2000 hours at 85°C under ripple current, and RoHS compliance. The unit is supplied in cardboard packing and is in mass production.

Key Features

• High Capacitance: 3.9 mF (3900 µF) rated capacitance for bulk energy storage and decoupling in high-voltage circuits.
• 450 V Rated Voltage: Rated for 450 V DC operation, suitable for high-voltage general-purpose applications within the stated rating.
• Screw Terminal Mounting: Radial, can-style body with M5 screw terminals for secure, low-resistance connections and straightforward installation.
• Thermal and Life Performance: Rated for −40°C to +85°C with a specified load life of 2000 hours at 85°C when subjected to rated ripple current.
• Ripple Current Capability: 14 A at 120 Hz and 19.6 A at 10 kHz, supporting sustained ripple handling in power applications.
• Leakage and Insulation Characteristics: Leakage current limited to ≤ 3√CV (µA) or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Compact Mechanical Size: Body diameter φ76.2 mm with overall dimensions noted as L: 9.5 cm × D: 7.62 cm (φ76.2×95L), enabling denser packaging for equipment downsizing.
• Regulatory Compliance: Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power systems: Provides high-voltage bulk capacitance where a secure screw-terminal connection and sustained ripple handling are required.
• Equipment downsizing efforts: Higher capacitance in a compact φ76.2×95L package supports reductions in overall system size.
• Industrial power electronics: Suited to general-purpose industrial equipment requiring 450 V, high-capacitance, screw-terminal capacitors with defined load-life performance.

Unique Advantages

• Sustained high-temperature life: 2000-hour load-life rating at 85°C with rated ripple current, offering predictable lifetime behavior under defined stress.
• Defined ripple performance: Specified ripple currents at 120 Hz (14 A) and 10 kHz (19.6 A) allow designers to match capacitor selection to expected operating conditions.
• Robust connection method: M5 screw terminals provide reliable mechanical and electrical connection for high-current, high-voltage applications.
• Clear electrical limits: Leakage current and insulation resistance specifications (≤ 3√CV µA or 5 mA; insulation resistance >100 MΩ at DC 500 V) support predictable designs and validation.
• RoHS compliance: Meets RoHS directive requirements for regulatory alignment in many markets.
• Mass-production availability: Product is in mass production and supplied in cardboard packing for standard handling and assembly processes.
