KEMET, part of YAGEO and a leading global supplier of electronic components, announced the launch of its new GTX series of metal-encased three-phase filters. This series addresses the growing demand for EMI-RFI filters to suppress electromagnetically conducted noise in general-purpose inverters and medical power supplies. KEMET GTX Metal Housing Filters meet 3-phase EMC requirements with various characteristics. Manufactured with nanocrystalline cores, these filters achieve excellent damping and attenuation characteristics in a compact size with a wider frequency range. In addition, six different combinations of Y capacitors can be selected to support various device topologies. These filters are the most volume efficient filters in the industry. Due to their high mechanical density, they are compact, lightweight and ideal for industrial and medical applications where EMC suppression is critical.
The rated voltage of the GTX series is 500VAC (50/60Hz), 500VDC (250VAC, 353.3VDC for c-UL). These filters operate over a temperature range of -25°C to +55°C. In addition, due to the use of nanocrystalline metal core, its rated current is 30A to 60A. GTX has passed UL, c-UL, TÜV safety certification, and is RoHS and REACH compliant. These filters comply with EU RoHS Directives 2011/65/EU and (EU) 2015/863. This series has excellent attenuation characteristics to meet the needs of design engineers to suppress noise in electronic equipment, so it is suitable for applications such as machine tools, industrial robots, wind power generation, power storage systems, medical equipment and diagnostic instruments.
Many solutions comparable to the GTX series are built using ferrite materials, resulting in a larger footprint and heavier weight. The series supports the industry's trend of increasing EMC requirements with volume-efficient, compact, and lightweight EMI-RFI three-phase filters.
