RO3150E

RO3150E • • • • • • Designed for Low Power 304 MHz Transmitters Very Low Series Resistance Quartz Frequency Stability Miniature 3.0 x 3.0 mm Surface-mount Case Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 RoHS Compliant 304 MHz SAW Resonator The RO3104E 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 304 MHz. This SAW is designed specifically for transmitters used in wireless security and remote control applications.

The design, manufacturing process, and specifications of this device are subject to change. 2. US or International patents may apply. 3. RoHS compliant from the first date of manufacture. 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.
