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.
