DK Series
The DK series RFI power line filters are general purpose common mode and differential mode filters with higher performance line-to-line attenuation than the VK series.
The E version of the DK series (EDK) has the same high performance line-to-line attenuation while still meeting the very low leakage current requirements of VDE portable equipment and UL544 non-patient care equipment.
The V version of the DK series (VDK) has the same high performance in a more cost-effective package for applications without strict leakage current requirements.
