LNU2H102MSEFBB

The LNU2H102MSEFBB is a Nichicon LNU-series aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage industrial power applications. This 1000 µF, 500 V polarized capacitor delivers high-voltage capability in a compact form factor and is engineered for inverter and regenerative circuits where high ripple and fast charge–discharge loading are encountered.

Built for demanding environments, the device is rated to operate from –40 °C to +105 °C and provides a load life of 5000 hours at 105 °C under rated ripple conditions. The LNU series supports rated voltages up to DC 525 V and is RoHS compliant.

Key Features

• Capacitance & Rated Voltage — 1000 µF nominal capacitance with a 500 V rated DC voltage (series rated up to DC 525 V).
• High-temperature Endurance — Rated for operation to 105 °C with a specified load life of 5000 hours at 105 °C when subjected to rated ripple current.
• High-frequency / Charge–Discharge Performance — Designed to cope with high-speed charge–discharge cycles and high-frequency regenerative voltages; specified ripple currents include 5 A at 120 Hz and 7 A at 10 kHz.
• Robust Screw-terminal Mounting — Radial can with screw terminals for secure, low-inductance connections in power assemblies; nominal bolt size and terminal pitch available per series drawing.
• Wide Operating Range — Operating temperature range from –40 °C to +105 °C supports industrial environments.
• Leakage Current Specification — Leakage current after 5 minutes is limited to 3√CV (µA) or 5 mA, whichever is smaller (per datasheet formula).
• Polarized Construction — Electrolytic polarized capacitor suitable for DC bus and energy-storage applications in power electronics.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Bulk and DC-link capacitance for inverter front-ends and power conversion modules where high voltage and long life are required.
• Regenerative Drive Circuits — Handles high-frequency regenerative voltages for AC servomotors and other regenerative systems.
• High-speed Charge–Discharge Systems — Energy storage and smoothing in circuits subject to frequent, rapid charge–discharge cycles.
• General Industrial Power Electronics — Filtering and energy buffering in motor drives, industrial converters, and similar applications requiring a compact high-voltage electrolytic solution.

Unique Advantages

• High-voltage capability in a compact package: 500 V rating (series up to 525 V) provides the voltage headroom needed in inverter and regenerative designs while occupying less space than larger high-voltage types.
• Designed for harsh thermal conditions: 5000 hours load life at 105 °C supports extended field service in elevated-temperature industrial installations.
• High ripple and high-frequency performance: Rated ripple currents of 5 A (120 Hz) and 7 A (10 kHz) help maintain stable DC bus performance under demanding switching conditions.
• Robust mechanical termination: Screw terminals provide secure electrical and mechanical connections suited to heavy-current power layouts.
• Durability under cycling: Series endurance data includes charge–discharge testing (50 million cycles at specified conditions), indicating suitability for frequent cycling applications.
• Regulatory compliance: RoHS conformity streamlines use in regulated markets and helps meet environmental requirements.
