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.
