For safety purposes, connect the output of filters to the IF amplifier through a D.C. blocking capacitor.Avoid applying a direct current to the output of ceramic filters.
(fn) means nominal center frequency 455kHz.
The order quantity should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
