Notes: Datasheet: https://linearparts.com/documents/muRata_datasheets.pdf (pg 26) Input & Output pins 1 & 3 must be the hot pins to work. Pins 2 & 4 are connected internally so they must be grounded in your circuit. Check page 28 of the datasheet for pinout. Murata recommends: "For safety purposes, connect the output of filters to the IF amplifier through a DC blocking capacitor. Avoid applying a direct current to the output of ceramic filters." Presumably they mean the input too.
