RFM products are now Murata products. RO3101A Designed for 433.92 MHz Transmitters Very Low Series Resistance 433.92 MHz Quartz Stability Surface-mount Ceramic Case Pb SAW Complies with Directive 2002/95/EC (RoHS) Resonator The RO3101A is a one-port surface-acoustic-wave (SAW) resonator packaged in a surface-mount ceramic case. It provides reliable, fundamental-mode quartz frequency stabilization of fixed-frequency transmitters operating at 433.92 MHz. The RO3101A is designed specifically for remote control and wireless security transmitters operating in Europe under ETSI EN 300 220-2.
