AEC-Q200 This component was always RoHS compliant from the first date of manufacture. • • • • • • Ideal for 303.825 MHz Transmitters Very Low Series Resistance Quartz Stability Surface Mount Ceramic Case with 21 mm 2 Footprint Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 RO3104D-1 RoHS Compliant 303.825 MHz SAW Resonator The RO3104D-1 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 303.825 MHz. This SAW is designed specifically for AM transmitters in wireless security and remote control applications operating in the USA under FCC Part 15, in Australia, in Japan, and in Korea.

RO3104D-1 (R) 06/11/2021 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.
