LNU2H332MSEGBN

The LNU2H332MSEGBN is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It delivers a high-voltage, polarized energy storage solution in a smaller package optimized for inverter and regenerative circuits.

With a rated voltage of 500 V, 3.3 mF capacitance, and a guaranteed load life of 5000 hours at 105°C under rated ripple conditions, this capacitor is targeted at industrial power supplies, AC servomotor regenerative systems and general inverter applications that demand high ripple capability and long-term thermal stability.

Key Features

• Capacitance & Tolerance — 3.3 mF nominal capacitance with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated voltage: 500 V DC, suitable for high-voltage inverter and regenerative circuits.
• High-Temperature Endurance — Operating temperature range −40°C to +105°C with a specified load life of 5000 hours at 105°C when exposed to rated ripple current and DC bias.
• High Ripple Current Capability — Ripple handling of 10.9 A at 120 Hz (low frequency) and 15.26 A at 10 kHz (high frequency), supporting high-speed charge–discharge loading and high-frequency regenerative voltages.
• Robust Electrical Reliability — Leakage current after 5 minutes at rated voltage is limited to not more than 3√(C·V) µA or 5 mA, whichever is smaller; insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.
• Endurance & Cycling — Meets series endurance criteria: after 5000 hours at 105°C under DC bias plus rated ripple, capacitance change, tan δ, and leakage current remain within specified limits. Also validated for extensive charge–discharge cycling per series test conditions.
• Package & Mounting — Radial can with screw terminals for secure, serviceable connections in industrial assemblies; polarized construction.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Physical Size — Smaller-sized design within the LNU series; dimensional example: L: 16.5 cm × D: 6.35 cm (height seated max: 6.496 inch), enabling denser power assemblies where space is limited.

Typical Applications

• Industrial Inverter Power Supplies — Energy smoothing and bulk storage for inverter front-ends and DC bus buffering in industrial power supplies.
• AC Servomotor Regenerative Circuits — Handling high-frequency regenerative voltages and supporting energy recapture in motion control systems.
• General Inverters — Bulk capacitance and high ripple support for general-purpose inverter designs including motor drives and renewable power converters.
• High-Speed Charge–Discharge Systems — Applications requiring frequent, rapid charge/discharge cycles where validated endurance and ripple handling are required.

Unique Advantages

• High-Voltage Capability: 500 V DC rating provides the voltage headroom needed for industrial inverter and regenerative circuits.
• Proven High-Temperature Life: Rated for 5000 hours at 105°C under ripple load, supporting long-term reliability in hot operating environments.
• Strong Ripple Performance: Measured ripple currents of 10.9 A (120 Hz) and 15.26 A (10 kHz) help reduce stress on system components and support high-frequency operation.
• Secure Screw-Terminal Mounting: Robust screw terminals facilitate reliable electrical and mechanical connections in industrial assemblies and ease maintenance.
• Electrical Safety Margins: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V/1 min dielectric proof between terminal and bracket provide measurable safety performance.
• RoHS Compliance: Meets RoHS requirements for environmentally regulated applications.
