LNK2W562MSEJ

The LNK2W562MSEJ from Nichicon is a screw-terminal, smaller-sized aluminum electrolytic capacitor in the LNK series, rated 5600 µF (5.6 mF) at 450 V. Designed for general-purpose power applications, it delivers bulk energy storage with a robust screw-terminal package for secure connections in high-voltage systems.

Key value propositions include sustained ripple-current capability, a long load-life rating at elevated temperature, and RoHS compliance—making it suitable where reliable high-voltage bulk capacitance and durable terminal mounting are required.

Key Features

• Capacitance & Voltage  5.6 mF (5600 µF) nominal capacitance with a rated voltage of 450 V and a capacitance tolerance of -20% to +20%.
• High Ripple Current  Rated ripple current of 18.6 A at 120 Hz and 26.04 A at 10 kHz, supporting demanding AC ripple conditions on high-voltage rails.
• Temperature Range & Endurance  Operating temperature range from -25 °C to +85 °C with a rated load life of 5000 hours at 85 °C under applied ripple current.
• Screw Terminal Package  Radial can with screw terminals provides secure, low-impedance connections for high-current and serviceable installations.
• Leakage Current Specification  After 5 minutes’ application of rated voltage, leakage current is not more than 3√CV (µA) or 5 mA, whichever is smaller (measured at 20 °C).
• RoHS Compliant  Conforms to RoHS directive requirements, suitable for designs requiring restriction of hazardous substances.
• Smaller-sized LNK Series  Part of Nichicon’s smaller-sized LNK family, offering compact high-voltage bulk capacitance in a screw-terminal format.

Typical Applications

• General-purpose power equipment  Bulk smoothing and energy storage on high-voltage DC rails where 450 V rating and high capacitance are required.
• Industrial power supplies  Supports ripple filtering and energy buffering in industrial converters and power modules using screw-terminal connections for robust assembly.
• DC-link and power conversion  Suitable for DC-link duties in converters where sustained ripple current handling and long life at 85 °C are important.
• Serviceable high-voltage assemblies  Screw terminals enable secure, maintainable mounting in applications that require periodic inspection or replacement.

Unique Advantages

• High bulk capacitance at high voltage: 5600 µF at 450 V provides substantial energy storage for high-voltage circuits, reducing the need for parallel components.
• Robust ripple-current capability: Rated ripple currents of 18.6 A (120 Hz) and 26.04 A (10 kHz) address both low- and high-frequency ripple demands.
• Long elevated-temperature life: 5000 hours load life at 85 °C under rated ripple conditions supports reliability in sustained thermal environments.
• Secure, low-impedance connections: Screw-terminal radial can package simplifies high-current wiring and mechanical retention in heavy-duty assemblies.
• Standards-oriented specification: Leakage current and endurance limits are defined per Nichicon’s LNK series datasheet, enabling predictable design margins.
• RoHS compliance: Meets RoHS directive requirements for restricted substances, assisting in regulatory conformity.
