LNU2H562MSEJBN

The LNU2H562MSEJBN is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage industrial power electronics. It delivers 5600 µF (5.6 mF) capacitance at a 500 V rating, with a series design targeted at inverter circuitry and regenerative power handling.

Engineered for demanding thermal and electrical environments, this capacitor supports operation from −40 °C to 105 °C, a rated voltage range up to DC 525 V, and a 5000‑hour load life at 105 °C under rated ripple current. It is RoHS compliant.

Key Features

• Electrical Capacity — 5600 µF (5.6 mF) nominal capacitance with ±20% tolerance (120 Hz, 20 °C), providing bulk energy storage for inverter and regenerative circuits.
• High Voltage Rating — 500 V rated voltage (series rated up to DC 525 V) for high‑voltage industrial power supplies and servo inverter applications.
• Ripple Current Capability — Supports 15.8 A at 120 Hz and 22.12 A at 10 kHz, enabling sustained AC ripple handling across low and high frequencies.
• Thermal and Lifecycle Performance — Operating range −40 °C to 105 °C with a specified load life of 5000 hours at 105 °C under rated ripple current.
• Charge–Discharge Endurance — Series-level endurance for charge–discharge behavior: tested for 50 million cycles (ΔV = rated voltage ±0.3, 3 Hz) with defined limits on capacitance change, dissipation factor, and leakage.
• Leakage and Insulation — Leakage current after 5 minutes is ≤ 3√(C·V) µA or 5 mA (whichever is smaller). Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Package and Mounting — Radial can with screw terminals for secure bolted connections; bracket supplied separately. Marked with white print on a black sleeve for clear ID.
• Series Advantage — High‑voltage, smaller sized design compared with the LNT series, intended to reduce board space for similar voltage ratings.
• Environmental Compliance — RoHS compliant to 2011/65/EU and (EU)2015/863.

Typical Applications

• Industrial Inverter Power Supplies — Bulk energy storage and DC link support for three‑phase inverters used in factory equipment and process drives.
• AC Servomotor Regeneration — Handles high‑frequency regenerative voltages and rapid charge–discharge cycles encountered in servo drive regenerative circuits.
• General Inverter Systems — Supports smoothing and ripple suppression in general inverter topologies for industrial motor control.

Unique Advantages

• High‑Voltage Capacity in Reduced Footprint — 500 V rating (series to 525 V) delivered in a smaller package compared with related series, helping save enclosure and board space.
• Designed for High Ripple and Fast Cycling — Rated ripple current at both low and high frequencies plus charge–discharge endurance make it suitable for fast switching and regenerative loads.
• Robust Thermal Endurance — 5000 hours at 105 °C under rated ripple current ensures consistent performance in high‑temperature industrial environments.
• Measurable Insulation and Voltage Withstand — Insulation resistance and AC voltage proof ratings provide clear, testable parameters for system safety and isolation design.
• Clear Identification and Mounting — Screw terminal radial can with white marking on a black sleeve simplifies installation and part identification in assemblies.
