STEP 1: SELECTING THE FILTER
s
Using the insert loss graphs on page 149
determine which filters provide the required
attenuation at the troublesome frequency, while
not affecting the signal frequency by more than
3 to 6 dB.
Choose the filter type, either feed-thru capacitor
or Pi. The Pi is generally considered better due
to its superior high frequency performance and
steeper curve. The feed-thru capacitor is lower
cost.
Select capacitance value.
Note the Spectrum letter designation for the
filter chosen from the table on page 149.

Choose either pin contacts (plug) or socket
contacts (receptacle).
Choose the required termination type.
From the table on the appropriate connector
page, using the filter letter designation chosen
in step 1 above, select the part number.

Refer to page 172 for special options
including heavy gold plating, 4-40 mounting
threads, grounding brackets, hardware,
and others.
Most options are available within the standard
lead times.
Some options require a part number suffix,
while other combinations may require factory
assistance for part number assignment. If a
suffix is shown, add it to your selected part
number. If more than one option is needed,
consult with factory for part number
assignment.
