LNT1E684MSE

The LNT1E684MSE is a high-capacitance aluminum electrolytic capacitor in a screw-terminal, radial can package. Specified for 25 V operation with 680000 µF capacitance and rated for continuous operation to 105°C, it provides bulk energy storage and high ripple-current handling for demanding power applications.

Designed for general-purpose industrial and power electronics use, this screw-terminal capacitor combines very large capacitance, high allowable ripple current, and robust temperature endurance to support DC link smoothing, bulk filtering and energy buffering in systems that require secure, low-impedance connections.

Key Features

• High Capacitance: 680000 µF (680 mF) for substantial bulk energy storage and smoothing of low-frequency ripple.
• Rated Voltage: 25 V rated voltage suitable for many low-voltage power systems.
• Screw Terminal Package: Radial can with screw terminals provides secure high-current connections and reliable mechanical mounting.
• High Ripple Current: Low-frequency ripple current of 24.2 A at 120 Hz and high-frequency ripple current of 27.83 A at 100 kHz to support switching supplies and heavy ripple loads.
• Wide Operating Temperature: Specified for –40°C to +105°C operation, enabling use across typical industrial temperature ranges.
• Robust Lifetime at High Temperature: Rated lifetime of 2000 hours at 105°C under rated ripple conditions for sustained high-temperature performance.
• RoHS Compliant: Compliant with RoHS directive requirements for environmental regulatory alignment.

Typical Applications

• Power Supplies: Bulk filtering and smoothing in industrial and commercial DC power supplies where large capacitance and high ripple capability are required.
• DC Link and Motor Drives: Energy buffering and ripple handling on DC link circuits and drive systems using screw terminals for secure high-current connections.
• Energy Storage / Backup: Short-term energy hold-up and buffering for systems that require rapid discharge/charge cycles and substantial stored energy at low voltage.
• Industrial Electronics: Filtering and decoupling in industrial control equipment that must operate across –40°C to +105°C and tolerate elevated ripple currents.

Unique Advantages

• Exceptional Bulk Capacity: 680000 µF provides significant stored energy per component, reducing the number of capacitors required for large-capacitance designs.
• High Ripple Handling: Specified ripple currents at both 120 Hz and 100 kHz reduce thermal stress in switching environments and improve system reliability under load.
• Secure Screw-Terminal Connections: Screw terminals enable high-current, low-resistance connections and simplify assembly and replacement in field serviceable equipment.
• High-Temperature Endurance: Rated for continuous use to 105°C with a specified 2000-hour lifetime at that temperature, supporting applications with elevated operating temperatures.
• Regulatory Compliance: RoHS-compliant construction supports environmental requirements for commercial and industrial electronics.
