The RHFR11C1960UB001 is a surface mount low-pass filter designed and manufactured by Enicom. It is an ultra-small, 1.1 by 0.9 mm package containing two surface acoustic wave (SAW) filters. These filters are used to reject interfering signals while allowing the through-signal of frequencies that are higher than the corner or cut-off frequency of the specified pass-band. The RHFR11C1960UB001 is a high-performance filter that meets the requirements of modern designs and applications. It also meets the requirements of the RoHS directive, meaning it is free of hazardous substances such as lead and is safe for the environment. This filter is an ideal choice for applications requiring minimal size and high performance.
