LNK2H392MSEJBN

The LNK2H392MSEJBN is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose high‑voltage applications. It combines a high rated capacitance of 3.9 mF with a 500 V rating and a compact screw‑terminal can package for secure, high‑current connections.

Engineered for applications that require high capacitance, high ripple handling and long endurance, this part is suited to systems operating across a broad temperature range with RoHS compliance for environmental compatibility.

Key Features

• High Capacitance / Voltage: 3.9 mF (3900 µF) nominal capacitance rated at 500 V, providing substantial energy storage in a single radial screw‑terminal can.
• Screw Terminal Mounting: Radial can with screw terminals for robust mechanical and electrical connections in power assemblies.
• Ripple Current Capability: Rated ripple current of 14.4 A at 120 Hz (low frequency) and 20.16 A at 10 kHz (high frequency), with frequency coefficients specified (1.00 at 120 Hz; 1.40 at 10 kHz or more).
• Endurance and Temperature Range: Load life of 5000 hours at 85°C with operating temperature range −25°C to +85°C.
• Leakage and Loss Characteristics: Specified leakage current of 4180 µA and tangent of loss angle (tan δ) of 0.2 for predictable performance under rated conditions.
• Electrical Isolation and Voltage Proof: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket as specified.
• Compact Mechanical Footprint: φ90 × 120 mm can size (approx. L: 12 × D: 9 cm) delivering high capacitance in a space‑efficient form factor.
• Compliance: RoHS compliant.

Typical Applications

• High‑Voltage Power Supplies: Bulk energy storage and smoothing where 500 V rating and high capacitance are required.
• Industrial Power Electronics: DC link and filtering in industrial converters and power modules that benefit from screw‑terminal mounting and high ripple capability.
• Energy Storage and Smoothing: Systems requiring substantial charge reservoir and long load life at elevated temperatures.

Unique Advantages

• High energy density at elevated voltage: 3.9 mF at 500 V provides significant charge storage without paralleled components.
• Robust current handling: High rated ripple current values with documented frequency coefficients allow predictable sizing for AC and high‑frequency ripple environments.
• Secure screw‑terminal interface: Facilitates reliable, low‑resistance connections ideal for high‑current assemblies and field serviceability.
• Documented endurance: 5000 hours at 85°C under rated ripple load supports long‑term deployment in demanding thermal conditions.
• Insulation and dielectric integrity: High insulation resistance and specified voltage‑proof testing between terminal and bracket increase system safety margins.
• Regulatory compatibility: RoHS compliance for use in environments with restricted substances requirements.
