Choosing the Right Capacitance for Your Filter Connector

(1) Determine the highest frequency that the filter connector needs to pass unaffected.
(2) Which frequencies are causing trouble, either with emissions or with immunity to interference?
(3) Scan the Insertion Loss charts on page 2 to select a filter which provides little or no insertion loss (filtering) at the frequency determined from step 1, yet gives the greatest possible insertion loss at the frequencies determined in step 2
