Low Series Resistance
Quartz Stability
Rugged, Hermetic, Low-profile SMD7.5X3.5 Case
The L433C is a true one-port, surface-acoustic-wave (SAW) resonator in low-profile SMD case. It provides reliable, fundamental-mode. quartz frequency stabilization of fixed-frequency transmitters operating at 433.92 MHz. The L433C is designed specifically for remote-controls and wireless security transmitters. Operating in the Europe underETS11-ETS 300 220 and in Germany under FTZ 17 TR 2100.
