RO3156A

• • • • • Ideal for European 868.95 MHz Transmitters Very Low Series Resistance Quartz Stability Surface-Mount Ceramic Case with 21 mm2 Footprint Complies with Directive 2002/95/EC (RoHS) RO3156A RO3156A-1 RO3156A-2 868.95 MHz SAW Resonator The RO3156A is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount ceramic case. It provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at 868.95 MHz. This SAW is designed specifically for remote-control and wireless security transmitters operating under ETSI-ETS 300 220 in Europe and under FTZ 17 TR 2100 in Germany.
