LNY2W332MSEFBN

The LNY2W332MSEFBN from Nichicon's LNY series is a screw-terminal aluminum electrolytic capacitor offering 3.3 mF (3300 µF) capacitance at a 450 V rating in a radial can with screw terminals. It is designed as a higher-capacitance, screw-terminal solution for general-purpose high-voltage applications.

With a wide operating temperature range and a specified load life, the LNY2W332MSEFBN targets equipment downsizing and robust energy-storage roles where high ripple handling and long-term endurance at elevated temperature are required.

Key Features

• Capacitance & Voltage: 3.3 mF (3300 µF) rated at 450 V for high-voltage energy storage and smoothing.
• High ripple current capability: 11.10 A at 120 Hz (low frequency) and 15.54 A at 10 kHz (high frequency) to support demanding AC ripple conditions.
• Screw terminal mounting & package: Radial can with screw terminals for secure high-current connections and easy installation in power assemblies.
• Endurance & thermal performance: Rated for 2000 hours at 85°C with an operating temperature range of −40°C to +85°C to support sustained high-temperature operation.
• Electrical characteristics: Tangent of loss angle (tan δ) of 0.25 and leakage current specified at 3650 µA to define loss and standby characteristics.
• Size & form factor: Physical dimension φ51 × 170 mm (L: 17 × D: 5.1 cm) for compact high-capacitance packaging suited to equipment downsizing.
• Regulatory compliance: RoHS compliant for restriction of hazardous substances.

Typical Applications

• High-voltage power supplies: Bulk energy storage and smoothing at 450 V, using the capacitor’s 3.3 mF capacitance and high ripple ratings to stabilize DC rails.
• Industrial power equipment: DC-link and filtering in power conversion systems where screw-terminal connections and high ripple capability are required.
• Equipment downsizing projects: Applications that require higher capacitance in a compact, screw-terminal radial can to reduce overall system volume.
• Uninterruptible power systems and energy modules: Local energy buffering and ripple handling in high-voltage backup or energy-storage circuits.

Unique Advantages

• High-voltage energy density: 3.3 mF at 450 V provides substantial bulk capacitance in a single radial can, enabling fewer parallel components.
• Designed for elevated ripple loads: Specified ripple currents at both low and high frequencies reduce the need for additional ripple-management components.
• Durable under heat stress: 2000-hour endurance at 85°C supports reliable long-term operation in thermally demanding environments.
• Secure, serviceable connections: Screw-terminal mounting simplifies assembly and provides robust mechanical and electrical contacts for high-current paths.
• Clear electrical definition: Specified tan δ and leakage current values allow predictable integration into power designs and margin calculations.
• RoHS compliant: Conforms to RoHS requirements for environmental and regulatory consistency.
