Principles of Noise Suppression by DC EMIFILr
DC EMI suppression filters absorb and eliminate high
frequency noise which may produce electromagnetic
interference in PC board circuits.
These filters are used in secondary circuits, and are small
in size and light in weight, which further enhances their
excellent noise suppression functions.
Chip and adhesive type filters can be mounted on PC
boards automatically.
These filters are effective in the suppression of radiation
noise in computers, peripheral equipment, and digital
circuit application equipment (including various types of
microcomputer application equipment), and function to
suppress noise in audio/visual equipment, which uses
digital memory chips and DSP.
These filters are also effective for improving the noise
immunity of equipment used in noisy environments (such
as electronic equipment for automobiles).
Generally, noise problems occur when the noise source
and electronic equipment sensitive to the influence of
noise are located in close proximity to one another.
In such situations, as shown in Figure at right, noise is
conducted through a conductor, which produces an
inductive field around the noise source.
To overcome such noise problems, it is preferable to
reduce the amount of noise generated by the noise
source or improve the noise resistance of adjacent
equipment.
In order to satisfy equipment performance specifications
and eliminate noise effectively at the same time, however,
it is customary to reduce the amount of noise generated
by the noise source, if it can't be eliminated altogether.
DC EMI suppression filters are used to suppress noise
produced by conductors. Noise radiation can be
suppressed, if it is eliminated with a filter in advance.
Generally, such noise suppression is achieved with DC
EMI suppression filters, according to the capacitive and
inductive frequency characteristics of the respective
conductors in the circuit.
Filters of this kind can be roughly divided into those:
(1) employing a capacitor,
(2) employing an inductor,
(3) employing a capacitor and inductor combination.
