SMD Crystal FILTER(MCF)

SMD crystal filter is a narrow frequency band pass filter. Due to the high-Q characteristics of the crystal, its pass-band bandwidth is narrower than the ordinary ceramic filters, and also it can pass multiple sets of filters to make the bandwidth more accurate. In order to meet the size of the handheld device and the convenience of PCB printing, the quartz crystal filter also provides SMD packaging. Usually used in low-frequency communication equipment, such as walkie-talkies, base stations, etc.
