Application Guidelines
Low Pass EMI filters are available in the following circuit
configurations, schematics are shown at right.
C Filter
The C filter is a three terminal feed-thru capacitor.
It is used to attenuate high frequency signals.
L Filter
An L filter consists of one inductive element and one
capacitive element. This type of filter can offer high
impedance or low impedance input depending upon
its orientation in the circuit. It is most commonly used in
applications where one has a high impedance load and a
low impedance source (see LT), or where one has a high
impedance source and a low impedance load (see LB).
Pi Filter
The Pi filter contains two capacitive elements and one
inductive element. It presents a low impedance to both the
source and the load. Because of the additional element, it
provides better high frequency performance than the C or
L configurations. Due to the possibility of ‘ringing’, Pi filters
are not recommended for switching applications.
Transient Suppression Pi Filter
The Transient Suppression Pi filter consists of a Pi filter
with a transient suppressor at the input to the filter. The
filter supplies the high frequency performance of the Pi
filter with the added protection of the transient suppressor
to protect the circuit from voltage spikes on the line.
T Filter
The T filter consists of two inductive elements and one
capacitive element. This circuit configuration presents a
high impedance input from either end. It has similar filter
performance to the Pi circuit configurations. It does not
have the ringing characteristic of the Pi filter and can be
used in switching applications.
Multi-section Filter (Double T)
Spectrum’s multi-element filters are designed for optimum
insertion loss in circuits with a relatively low source and
load impedance. These filters are also recommended in
any application where a high degree of filtering is required.
The unit utilizes an inductor input for the best compatibility
with a MIL-STD-461 test setup (10 µF feed-thru capacitor).
