REYCONNS SAW Resonator R390 REYCONNS CHINA LIMITED www.reyconns.com Recommended Reflow Soldering Diagram Notes 1. As a result of the particularity of inner structure of SAW products, it easy to be breakdown by electrostatic, so we should pay attention to ESD protect in the test. 2. Static voltage between signal load and ground may cause deterioration and destruction of the component. Please avoid static voltage. 3. Ultrasonic cleaning may cause deterioration and destruction of the component. Please avoid ultrasonic cleaning. 4. Only leads of component may be soldered. Please avoid soldering another part of component. 5. There is a close relationship between the device's performance and matching network. The specifications of this device are based on the test circuit shown above. L and C values may change depending on board layout. Values shown are intended as a guide only.
