The SPDL485025 product series 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 consumer,
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 achieve the most effective noise
suppression, offering high common mode impedance in the noise
band with the highest possible current ratings in most models.
