RO3112D RFMi

AEC-Q200 This component was always RoHS compliant from the first date of manufacture. Ideal for European 433.420 MHz Remote Control and Security Transmitters RO3112D Very Low Series Resistance Pb Quartz Stability Complies with Directive 2002/95/EC (RoHS) 433.420 MHz Tape and Reel Standard per ANSI/EIA-481 SAW The RO3112D 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 Resonator operating at 433.420 MHz. This SAW is designed specifically for remote control and wireless security transmitters operating in Europe under ETSI I-ETS 300 220.
