LNU2H272MSEH

The LNU2H272MSEH is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNU series designed for high‑voltage industrial power applications. It provides 2.7 mF (2700 µF) capacitance at a 500 V DC rating with polarized construction and a compact radial can package with screw terminals.

Engineered for inverter and regenerative circuits, this part is suited to industrial power supplies and AC servomotor inverter systems that require high voltage handling, robust ripple performance, and long service life at elevated temperatures.

Key Features

• High Voltage Rating — Rated at 500 V DC with a rated voltage range up to DC 525 V, enabling use in high‑voltage inverter and power supply sections.
• Large Capacitance — 2.7 mF (2700 µF) nominal capacitance with ±20% tolerance (120 Hz, 20°C) for energy buffering and smoothing in power circuits.
• High Ripple Current Capability — Rated ripple current of 9.6 A at 120 Hz and 13.44 A at 10 kHz supports high ripple loading and high‑frequency charge/discharge cycles.
• High‑Temperature Endurance — Specified for operation from −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple and DC bias.
• Screw Terminal, Radial Can Package — Robust screw‑terminal mounting and radial can construction simplify installation in industrial power assemblies; brackets supplied separately.
• Compact High‑Voltage Design — Part of a “High Voltage, Smaller Sized” series, offering a smaller footprint compared with previous high‑voltage models while maintaining voltage and lifetime performance.
• Polarized Electrolytic — Polar type suited for DC energy storage and smoothing in power electronics topologies.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Energy storage and smoothing for inverter front ends and DC bus applications in industrial power systems.
• AC Servomotor Regenerative Circuits — Handles high‑frequency regenerative voltages encountered in motor drive regeneration and braking circuits.
• General Inverter Systems — Supports high‑voltage charge/discharge cycles and ripple in general inverter and power conversion designs.

Unique Advantages

• High‑Voltage Handling: 500 V rating (with series rated up to DC 525 V) enables use in demanding DC bus and inverter circuits without up‑rating components.
• Designed for High‑Frequency Loading: Ripple current ratings at 120 Hz and 10 kHz plus explicit endurance for high‑speed charge/discharge make it suitable for regenerative and high‑frequency applications.
• Long Life at Elevated Temperature: 5000 hours life at 105°C under rated ripple and DC bias supports extended field service in industrial environments.
• Robust Mechanical Termination: Screw terminals and radial can package provide secure, serviceable connections for heavy‑current industrial wiring.
• Compact Form Factor: Part of a smaller‑sized high‑voltage series, helping to reduce enclosure space for high‑voltage power stages.
• Regulatory Compliance: RoHS conformity supports use in equipment targeted for regulated markets.
