The SPDL product Series is a new family of ultra-compact SMD common

mode chokes for EMI suppression of differential mode noise as required in

electronic devices filtering signals over network interfaces. It is applicable

in the consumer, industrial and automotive interface market.

In automotive, electronic design applications involve applying power over

high speed data lines, catering to protocols/communication interfaces

present in the cabin of an automobile, such as CAN bus, Ethernet, USB

or FlexRay. Conversely, for consumer and industrial applications such as

computers, peripherals and personal charging devices, more proprietary

protocols may even be utilized, furthering the need for differential noise

suppression. Signal provides solutions for both market segments.

In conjunction with the latest winding technology and ferrite cores, Signal’s

designs achieve excellent noise suppression, offering high common mode

impedance in the noise band and low differential mode impedance in

the signal band. A low differential mode impedance with a high coupling

coefficient assures virtually no distortion of high-speed signals.
