DLF Series

Data Line EMI Filters

Our DLF Series data line EMI filters provide common mode and differential mode filtering in a single component. They reduce conducted noise by a factor of 32 from 5 MHz to 300 MHz and pass data frequencies below 200 MHz with minimal attenuation.

Hinweise

For optional cover add "C" to part number just before the "L": e.g. DLF 8500CL. Not available on 3500, 4000 and 4500 parts.
Frequency at which the differential mode attenuation equals 3 dB.
Inductance is per winding.
DCR is per winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Interwinding isolation measured for one minute.
