LNT2H392MSEH

The LNT2H392MSEH is a Nichicon LNT series aluminum electrolytic capacitor in a screw-terminal can, rated for 500 V and 3.9 mF capacitance. Designed for general-purpose power applications, it delivers high ripple-current capability and robust thermal endurance up to +105°C.

With a radial can and screw-terminals for secure electrical and mechanical connections, this capacitor supports demanding DC link and power-smoothing roles where high voltage, elevated temperature tolerance, and reliable long-term operation are required.

Key Features

• High Voltage Rating – Rated voltage: 500 V to support high-voltage DC link and power-supply applications.
• Large Capacitance – Capacitance: 3.9 mF with ±20% tolerance for bulk energy storage and smoothing.
• High Ripple Current Capability – Ripple current: 14.1 A at 120 Hz (low frequency) and 19.74 A at 100 kHz (high frequency), enabling handling of substantial AC ripple without excessive heating.
• High-Temperature Endurance – Operating temperature: -25°C to +105°C and rated lifetime: 2,000 hours at +105°C for the 500 V version, supporting sustained operation in elevated-temperature environments.
• Screw Terminal Package – Radial can with screw terminals provides robust electrical connection and easy mechanical mounting for panel or chassis installations.
• Polarized Construction – Polarized electrolytic type appropriate for DC applications where polarity is controlled.
• RoHS Compliant – Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size – Compact high-capacitance form factor with dimensions L: 15 cm × D: 7.62 cm and a maximum seated height of 5.906 inch for planning mechanical integration.

Typical Applications

• Power Supplies – Bulk smoothing and energy storage in high-voltage DC power supplies where 500 V rating and high ripple-current capability reduce voltage ripple and thermal stress.
• Industrial Drives & Inverters – DC link and filtering in motor drives and inverter systems that require durable capacitors rated for +105°C ambient operation.
• Uninterruptible Power Systems – Energy buffering and smoothing in UPS and backup power equipment that benefit from large capacitance and robust ripple handling.
• High-Voltage Power Electronics – General-purpose energy storage and decoupling in high-voltage assemblies where secure screw-terminal connections simplify installation and maintenance.

Unique Advantages

• 500 V Capability: Enables direct use in high-voltage DC-link applications without series stacking or complex architectures.
• High Ripple Handling: Specified ripple currents at 120 Hz and 100 kHz minimize temperature rise and extend operating life under AC-stressed conditions.
• Elevated Temperature Rating: Rated for operation to +105°C with a defined 2,000-hour life at that temperature for the 500 V variant, providing predictable endurance in hot environments.
• Secure Screw-Terminal Mounting: Robust mechanical and electrical termination reduces contact resistance and simplifies field wiring and maintenance.
• Large Bulk Capacitance in a Compact Can: 3.9 mF of capacitance in a radial can supports high energy density for smoothing and decoupling while conserving board and chassis space.
• Regulatory Compliance: RoHS compliance supports integration into products targeting restricted-substance requirements.
