ceramic ?lters that use the thickness expander mode
of the piezoelectric ceramic.
As part of the environment protection program, the solder
for terminal plating and terminal-element connection
inside of the ceramic ?lter contain no lead (Pb).

For safety purposes, connect the output of ?lters to the IF ampli?er through a D.C. blocking capacitor. Avoid applying a direct current to the output of ceramic ?lters.
The order quantity should be an integral multiple of the "Minimum Quantity" shown in the package page.
