LNUN7562MSEJ

The LNUN7562MSEJ is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage industrial power applications. As part of the LNU series, it delivers a 525 V DC rating in a smaller-sized, screw‑terminal can suitable for inverter circuitry and high‑frequency regenerative environments.

Engineered for demanding thermal and electrical conditions, the capacitor is specified for operation from ‑40 °C to 105 °C and a rated load life of 5000 hours at 105 °C under applied ripple current. It is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• High Voltage Rating — Rated voltage up to DC 525 V, enabling use in high‑voltage inverter and regenerative circuits.
• Capacitance — 5.6 mF nominal capacitance with ±20% tolerance (120 Hz, 20 °C), suitable for bulk energy storage and smoothing in power stages.
• High Temperature Endurance — Rated for continuous operation from ‑40 °C to +105 °C with a specified load life of 5000 hours at 105 °C under rated ripple conditions.
• High Ripple Current Capability — Supports 17.5 A at 120 Hz and 24.5 A at 10 kHz, designed to handle high‑frequency and high‑amplitude ripple in inverter/regenerative systems.
• Robust Endurance and Charge‑Discharge Behavior — Meets series endurance criteria: capacitance within ±20% after endurance and charge‑discharge cycling; tan δ and leakage current remain within specified limits after tests described in the series datasheet.
• Screw Terminal Package — Radial can with screw terminals for secure, low‑impedance connections in power assemblies; nominal bolt sizing and bracket options follow LNU series mechanical details.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is limited to 3√CV (µA) or 5 mA, whichever is smaller (C = µF, V = V), per the series specification.
• Environmental Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Energy storage and smoothing in inverter front‑end and DC bus circuits where high voltage and high ripple handling are required.
• AC Servomotor Drives — Absorbing regenerative energy and supporting high‑frequency regenerative voltage in motor control systems.
• General Inverters — Bulk capacitance for high‑voltage inverter stages, supporting rapid charge/discharge cycles.
• High‑Frequency Power Electronics — Suited for designs requiring reliable performance under high‑frequency ripple and repeated charge/discharge loading.

Unique Advantages

• High Voltage Handling: 525 V DC rating allows use in higher‑voltage inverter and regenerative topologies without additional series stacking.
• Strong Ripple Performance: Specified ripple currents at both low and high frequencies support designs with substantial AC ripple and switching noise.
• Thermal Durability: 105 °C maximum operating temperature and a 5000‑hour rated life at that temperature provide durability for heavy‑duty industrial deployments.
• Screw‑Terminal Mechanical Integrity: Screw terminals provide secure, low‑resistance connections for high‑current paths common in power assemblies.
• Compact LNU Series Form Factor: Smaller size relative to earlier LNT series variants helps reduce enclosure and bracket space in dense power modules.
• RoHS Compliance: Meets current RoHS directives for use in regulated regions and assemblies.
