Three-phase EMI-RFI filter’s nanocrystalline metal core improves efficiency

Claimed to be the industry’s most volumetric-efficient EMI-RFI three-phase filter, the GTX series has been designed with a nanocrystalline metal core by Kemet. This series supports the industry’s trend for increased EMC requirements, with a volumetrically efficient, compact and lightweight EMI-RFI three-phase filter. Many comparable models use ferrite materials, which have a larger footprint and are heavier in weight, said Kemet. 

The metal box three-phase filter’s high density mechanical structure is compact and lightweight, making it suitable for EMC noise suppression in general purpose inverters and medical power supplies. The nanocrystalline metal core results in rated currents of 30 to 60A and contributes to damping and attenuation characteristics, coupled with a broad frequency range. 

Six combinations of Y capacitors can be selected to support various equipment topologies. 

The GTX series is rated to 500V AC (50 / 60Hz), 500V DC (250V AC, 353.3V DC for c-UL). The filters can operate in a temperature range from -25 to +55 degrees C. The  GTX is safety-certified by UL, c-UL, TüV and is RoHS as well as REACH-compliant. The filters comply with EU RoHS Directive 2011/65/EU and (EU)2015/863. 

In addition to medical equipment, diagnostic instruments and industrial robots, the GTX filter can be used for suppressing noise in electronic equipment with superior attention characteristics, such as power storage systems, wind-power generation and machine tools.

The GTX series is available immediately via Kemet distributors. 

Kemet is a subsidiary of Yageo and offers a broad selection of passive components, including capacitors, resistors, magnetics, circuit protection, sensors and actuators. 

Yageo Group includes Yageo, Kemet and Pulse brands, the world’s top three passive component suppliers, claimed the company. It offers worldwide production and sales capabilities a complete offering of chip resistors, polymer, tantalum, MLCC, film, aluminium electrolytic capacitors, circuit protection devices, magnetics, antennas, sensors, and actuators.
