LNK2W272MSEGBN

The LNK2W272MSEGBN is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power electronics requiring high-voltage bulk capacitance in a smaller-sized package. It combines a 2700 µF capacitance with a 450 V rated voltage, high ripple-current capability, and RoHS compliance to support robust energy storage and smoothing in a range of systems.

Built for continuous operation across -25°C to +85°C with a rated load life of 5000 hours at 85°C, this capacitor targets applications where sustained ripple handling and long-term reliability are required in a radial can with screw terminals.

Key Features

• High Voltage Rating — 450 V rated voltage supports high-voltage energy storage and filtering requirements in power electronics.
• Substantial Capacitance — 2.7 mF (2700 µF) bulk capacitance provides effective smoothing and bulk energy storage for DC link and power supply applications.
• High Ripple Current — Rated ripple current of 10.5 A at 120 Hz and 14.7 A at 10 kHz supports heavy ripple environments and reduces thermal stress during operation.
• Screw Terminal Mounting — Radial can with screw terminals simplifies secure electrical connection and heavy-current installations.
• Operational Temperature Range — Specified for -25°C to +85°C to cover a wide range of industrial operating environments.
• Long Load Life — Load life specification of 5000 hours at 85°C under rated ripple current demonstrates endurance for long-term use.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted-substance requirements.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√CV (µA) or 5 mA, whichever is smaller, for controlled quiescent behavior.

Typical Applications

• General-purpose power electronics — Bulk energy storage and smoothing where 450 V rating and 2700 µF capacitance are required for DC link and filter functions.
• Industrial power supplies — Handles sustained ripple currents and high-voltage operation for industrial converters and power modules.
• Inverters and motor drives — Provides bulk capacitance and ripple-current capacity to support DC bus stability in inverter and drive systems.
• Uninterruptible power supplies (UPS) — Energy buffering and smoothing in high-voltage sections requiring long-life operation at elevated temperatures.

Unique Advantages

• High-voltage, high-capacitance combination: 450 V and 2700 µF deliver substantial stored energy in a smaller-sized radial can, reducing the need for multiple parallel capacitors.
• Designed for high ripple environments: Rated ripple currents up to 14.7 A at high frequency minimize heating under AC ripple stress and support reliable operation.
• Durable endurance rating: 5000 hours at 85°C under rated ripple conditions provides predictable long-term performance for sustained-duty systems.
• Screw-terminal robustness: Heavy-duty mechanical and electrical connections simplify installation and ensure dependable current transfer in high-power assemblies.
• Compliance and manufacturability: RoHS compliance and a standardized radial can form factor make integration straightforward for regulated and commercial products.
• Controlled leakage behavior: Defined leakage current limits after voltage application help manage startup and standby current budgets.
