erniceThe SFR433H with SAW Resonators SMD5035 RoHS manufactured by Sfernice is a SAW (Surface Acoustic Wave) resonator/filter. It is a surface-mountable component that is designed to be used in radio frequency (RF) circuits. It is constructed with an atomically smooth quartz substrate on which thin layers of metallic electrodes are deposited. The SFR433H operates in the 433MHz frequency range and has a temperature stability of ±30ppm. It has a maximum equivalent series resistance (ESR) of 3.7Ohm and a capacitance of 0.025pF. The component is RoHS compliant, meaning that it contains no hazardous materials, and it is also compliant with the UL, CSA, and TUV safety standards.
