AEC-Q200 This component was always RoHS compliant from the first date of manufacture. RO3073A Designed for 315.0 MHz Transmitters Pb Very Low Series Resistance 315.0 MHz Quartz Stability Surface-mount Ceramic Case SAW Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 Resonator The RO3073A 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 315.0 MHz. This SAW is designed specifically for remote control and wireless security transmitters.

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 Terminal recommended to help reduce parasitic Temperature Characteristics capacitance in the circuit.
