Designed for elevated operating conditions, this polarized capacitor is rated for operation from –40°C to +105°C and a rated load life of 5000 hours at 105°C, offering durability and performance for demanding industrial environments.

Key Features

• Electrical Performance — 3.9 mF (3900 µF) capacitance with a 500 V DC rating and ±20% tolerance (120 Hz, 20°C) for bulk energy storage and voltage stabilization.
• High Ripple Current Capability — Rated ripple current of 12.4 A at 120 Hz and 17.36 A at 10 kHz to support heavy AC ripple and high-frequency operation.
• Thermal and Endurance — Operating range from –40°C to +105°C with a rated load life of 5000 hours at 105°C; endurance and charge–discharge characteristics are specified by the LNU series.
• Robust Mechanical Design — Screw terminal, radial can package provides secure, low-resistance connections for high-current applications; nominal diameter and terminal details follow the LNU series mechanical drawing.
• Compact High-Voltage Form Factor — High-voltage performance in a smaller-sized package (φ90×105L) compared with larger series options within the family.
• Packaging & Production — Supplied in cardboard packing and produced for mass production volumes.
• Regulatory — RoHS compliant as stated for the LNU series.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and DC link capacitance for inverter circuitry and industrial supply rails.
• Motor Drives & Regenerative Systems — Energy buffering and high-frequency regenerative voltage handling for AC servomotor and drive applications.
• Inverter Systems — Support for charge/discharge cycles and transient current demands in general inverter designs.
• High-Frequency Energy Storage — Suitable where high ripple currents and fast charge–discharge behavior are required.

Unique Advantages

• High-Voltage Capability: 500 V DC rating enables use in higher-voltage DC link and inverter circuits without series arrangements.
• High Ripple Handling: Specified ripple current at both low and high frequency (12.4 A at 120 Hz; 17.36 A at 10 kHz) supports demanding AC ripple and switching environments.
• Elevated Temperature Endurance: Rated life of 5000 hours at 105°C provides measurable longevity for sustained high-temperature operation.
• Secure Screw-Terminal Connections: Radial can with screw terminals facilitates reliable, low-impedance wiring for high-current assemblies.
• Compact, High-Voltage Design: φ90×105 mm footprint packs substantial capacitance into a smaller high-voltage package within the LNU family.
• RoHS Compliant: Meets environmental standards as declared for the LNU series.

Why Choose LNU2H392MSEJBB?

The LNU2H392MSEJBB positions itself as a robust, high-voltage energy storage component for industrial power-electronics designs that require substantial capacitance, high ripple capability, and reliable operation at elevated temperatures. Its screw-terminal can and compact φ90×105 mm form factor make it well suited to DC link, inverter and regenerative drive topologies where secure, high-current connections and long-term thermal endurance matter.

Engineers specifying components for industrial inverters, motor drives, and high-frequency power supplies will find the measurable specifications—500 V rating, 3.9 mF capacitance, defined ripple currents, and a 5000-hour life at 105°C—helpful for predictable design margins and lifecycle planning.
