The SPDL764WM, SPDL975WM, SPDL121006 and SPDL151306

product family is an expansion of Signal’s SPDL Series of compact

SMD common mode chokes for suppression of common mode

noise as required in electronic devices filtering power line signals. It

is applicable to high density devices in the customer, industrial and

interface markets.

In many of today’s electronic designs, smaller size and weight

reduction is always of interest. This is evident in many applications

such as computers, peripherals and personal charging devices

which employ surface mount technology. Performance is still

essential with higher current capability.

In conjunction with the latest winding technology and ferrite cores,

Signal’s SPDL Series II designs address these applications to

achieve the most effective noise suppression, offering high common

mode impedance in the noise band with the highest possible

current ratings in most models.
