LNU2H272MTEH

The LNU2H272MTEH is a screw-terminal aluminum electrolytic capacitor designed for high-voltage industrial power electronics. It is a smaller-sized, high-voltage unit rated for 500 V DC with a capacitance of 2.7 mF and polarized construction.

Built for demanding inverter and regenerative circuits, the capacitor is specified for operation from –40°C to +105°C, a 5000-hour load life at 105°C under rated ripple, and elevated ripple current capability to support high-frequency charge–discharge applications.

Key Features

• Rated Capacitance: 2.7 mF with a tolerance of –20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating: 500 V DC nominal rating (part of a series rated up to DC525 V), suitable for high-voltage DC link and inverter applications.
• Temperature & Reliability: Operating range –40°C to +105°C with a specified load life of 5000 hours at 105°C under rated ripple current.
• High Ripple Current Capability: Rated ripple current of 9.6 A at 120 Hz and 13.44 A at 10 kHz to support high-frequency and regenerative loads.
• Robust Mechanical Package: Screw-terminals with stud/bolt mount (radial can) for secure electrical and mechanical connection in industrial assemblies.
• Compact Footprint: Smaller-sized construction than comparable LNT-series parts, with physical dimensions L: 10.5 × D: 7.62 cm and a seated height of up to 4.134 inches.
• Polarized Design: Polar electrolytic capacitor suitable for DC bus, energy storage and charge–discharge buffering in power electronics.
• RoHS Compliance: Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: DC link and smoothing in inverter front-ends and industrial power modules where high DC voltage and compact size are required.
• Inverter Circuits: Energy buffering and ripple handling for general inverter designs and motor-control inverters.
• Regenerative Systems: High-frequency regenerative voltage support for AC servomotors and systems with frequent charge–discharge cycles.
• High-Frequency Charge–Discharge: Applications requiring robust performance under fast charge–discharge loading and elevated ripple currents.

Unique Advantages

• High-voltage capability: 500 V rating enables use in DC link and high-voltage sections of power electronics designs.
• Designed for elevated temperatures: Operation to 105°C with a proven 5000-hour life under rated ripple current supports long-term reliability in hot operating environments.
• Strong ripple performance: Specified ripple currents at both low and high frequencies (9.6 A at 120 Hz; 13.44 A at 10 kHz) address both mains-frequency smoothing and high-frequency regenerative demands.
• Secure screw-terminal mounting: Stud/bolt mount and radial can package provide robust mechanical retention and reliable electrical connections for industrial assemblies.
• Space-efficient form factor: Smaller-sized design compared with the LNT family reduces board and cabinet footprint while maintaining high-voltage performance.
• Regulatory compliance: RoHS conformity simplifies integration into designs targeting markets with restricted substances requirements.
