SP418R
418MHz SAW Resonator
The SP418R is a true one-port ,surface-acoustic-wave(SAW) resonator in a low profile TO-39 case .It
provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters
operating at 418MHz. The SP418R is designed specifically for remote-control and wireless security
transmitters operating in Europe under ETSII-ETS 300 200 and in Germany under FTZ 17 TR 2100
