RO3073A-16

AEC-Q200 This component was always RoHS compliant from the first date of manufacture. RO3073A-16 • • • • • • Designed for 315.050 MHz Transmitters Very Low Series Resistance Quartz Stability Surface-mount Ceramic Case Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 RoHS Compliant 315.050 MHz SAW Resonator The RO3073A-16 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 315.050 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 recommended to help reduce parasitic capacitance in the circuit.
