RO3073D • • • • • • • Ideal for 315 MHz Remote Control and Security Transmitters Very Low Series Resistance Quartz Stability Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 Moisture Sensitivity Level:1 AEC-Q200 Qualified RoHS Compliant 315.0 MHz SAW Resonator The RO3073C 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 315.0 MHz. This SAW is designed specifically for remote control and wireless security transmitters.

RO3073D (R) 12/07/2021 Page 1 of 3 www.rfmi.co Electrical Connections Pin The SAW resonator is bidirectional and may be installed with either orientation. The two terminals are interchangeable and unnumbered. The callout NC indicates no internal connection. The NC pads assist with mechanical positioning and stability. External grounding of the NC pads is recommended to help reduce parasitic capacitance in the circuit.
