RO3104  
• Ideal for 303.825 MHz Transmitters in USA and Others  
• Very Low Series Resistance  
• Quartz Stability  
• Rugged, Hermetic, Low-Profile TO39 Case  
• Complies with Directive 2002/95/EC (RoHS)  
303.825 MHz

The RO3104 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It  
provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating  
at 303.825 MHz (often referred to as the 303.875 MHz channel). The RO3104 is designed for remote-control  
and wireless security transmitters operating in the USA under FCC Part 15, in Japan, in Australia, and in  
Korea.
