CONCORD, Calif., 23 July 2011. Engineers at Calex Manufacturing Co., in Concord Calif., released a new DC-DC converter filter called the the EFIL-100-10 input filter. The device provides a printed circuit board (PCB) mount plug and play function to help control electromagnetic interference (EMI) for board level DC-DC converter applications.

The Calex product is 1 by 2 by 0.47 inches and is designed to work with other Calex converters. The EFIL-100-10 can be used with a single DC-DC converter or as the front end for multiple Calex converters as long as the total input current does not exceed 10 amps.
The filter contains input and output capacitors plus differential and common mode inductors.
The EFIL-100-10 is isolated input to output with an isolation voltage of 1,000 volts direct current (VDC). The maximum input voltage for the EFIL-100-10 is 100 VDC. The maximum input frequency is 100 hertz. The case operating temperature range is -40 to 80 degrees Celsius at 7 amps. The storage range is -40 to 105 C. The unit is housed in a water washable plastic, non-conductive case and is available in RoHS and non-RoHS construction.
