LNU2H102MSEFBN

The LNU2H102MSEFBN is a Nichicon LNU series aluminum electrolytic capacitor in a screw-terminal radial-can package, specified at 1000 µF and 500 V DC with polarized terminals. It is designed for industrial power electronics, including inverter circuitry and high-frequency regenerative circuits for AC servomotors and general inverters.

Key value comes from high-voltage capability with a rated voltage range up to DC525V, compact high-voltage sizing compared with legacy designs, and extended load life under elevated temperature and ripple conditions.

Key Features

• Capacitance & Voltage — 1000 µF (1 mF) nominal capacitance rated for 500 V DC; part of an LNU series with rated voltage range up to DC525V.
• High-temperature endurance — Engineered for continuous operation from −40 °C to +105 °C with a load life of 5000 hours at 105 °C under rated ripple current.
• Ripple current handling — Supports 5 A at 120 Hz and 7 A at 10 kHz, enabling use in both line-frequency and higher-frequency power stages.
• Screw terminal mounting — Radial can with screw terminals for secure, serviceable electrical and mechanical connections in power assemblies.
• Charge–discharge endurance — Specified to withstand 50 million charge–discharge cycles (ΔV = rated voltage ±0.3, 3 Hz) while meeting capacitance, tan δ and leakage requirements.
• Compact high-voltage design — High-voltage behavior in a smaller size compared to earlier LNT series designs; physical size L: 9 cm × D: 5.1 cm and seated height up to 3.543 inches.
• Polarized construction — Standard polarized electrolytic device for DC link and energy-storage applications.
• RoHS compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies: Bulk DC-link and energy-storage for inverter front ends where high voltage and elevated temperature endurance are required.
• Inverter motor drives: High-frequency regenerative voltage support for AC servomotor and general inverter circuits.
• High-rate charge–discharge systems: Circuits that experience frequent or rapid charge and discharge cycles, supported by the capacitor’s specified endurance.
• High-voltage DC bus: Energy buffering and smoothing on DC buses up to the rated voltage range for industrial power electronics.

Unique Advantages

• High-voltage capability: Rated at 500 V with series support up to DC525V, enabling use in demanding DC-link and inverter designs.
• Extended thermal life: 5000 hours at 105 °C under rated ripple current provides predictable long-term performance in hot environments.
• Robust ripple performance: Separate ripple specifications for 120 Hz and 10 kHz (5 A and 7 A respectively) help designers match components to both low- and high-frequency power stages.
• Designed for frequent cycling: Proven endurance for 50 million charge–discharge cycles reduces maintenance and replacement needs in cyclic applications.
• Serviceable screw-terminals: Screw terminal construction simplifies installation, wiring, and field service in industrial systems.
• Regulatory compliance: RoHS conformity supports use in projects with restricted-substance requirements.
