LNT2W682MSEJ

The LNT2W682MSEJ is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require high voltage and large capacitance. It combines a 6.8 mF rated capacitance with a 450 V rating in a robust radial can with screw terminals.

Engineered for demanding operating conditions, this part delivers high ripple-current capability and extended load life at elevated temperature, making it suitable for systems that need bulk energy storage and steady performance up to +105°C.

Key Features

• Capacitance & Voltage: 6.8 mF (6800 µF) capacitance at a 450 V rated voltage for high-energy bulk storage in a single component.
• Screw-Terminal Mounting: Radial can with screw terminals provides secure, low-impedance connections for high-current installations.
• High Ripple Current Handling: 28.3 A at 120 Hz (low frequency) and 39.62 A at 100 kHz (high frequency) to support heavy ripple loads.
• Thermal & Lifetime Performance: Rated for operation from −25°C to +105°C with a load life of 5000 hours at +105°C under rated ripple conditions.
• Leakage and Loss Characteristics: Specified leakage current of 5000 µA and tanδ of 0.2 (measured at 120 Hz), enabling predictable loss and leakage behavior.
• Size and Packaging: φ90 × 170 L form factor (size dimension L: 17 x D: 9 cm) in a radial can; supplied in cardboard packing for mass production.
• Compliance: RoHS compliant.

Typical Applications

• General-Purpose Power Systems: Bulk energy storage and smoothing in systems that require a 450 V, high-capacitance solution.
• High-Ripple Environments: Filtering and decoupling where high ripple current capability (28.3 A @120 Hz, 39.62 A @100 kHz) is required.
• High-Temperature Installations: Applications needing sustained operation at elevated temperatures up to +105°C with a specified 5000-hour load life.

Unique Advantages

• High Voltage & High Capacitance in One Component: 450 V rating combined with 6800 µF reduces the need for parallel capacitor arrays to meet energy storage requirements.
• Robust Connector Interface: Screw terminals provide reliable mechanical and electrical connection for high-current applications and easy field wiring.
• Designed for High Ripple Loads: Specified ripple currents at low and high frequencies support both power-line and switching-frequency stress without overstressing the capacitor.
• Long Life at Elevated Temperature: 5000 hours rated life at +105°C supports designs with sustained high-temperature operation.
• Predictable Electrical Behavior: Specified tanδ (0.2 at 120 Hz) and defined leakage current (5000 µA) make system-level loss and bleed calculations straightforward.
• Regulatory Compliance: RoHS compliance supports inclusion in regulated products and assemblies.
