RO3104E-1

• • • • • • • RO3104E-1 Ideal for 303.825 MHz Remote Control and Security Transmitters RoHS Very Low Series Resistance Quartz Frequency Stability Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 Moisture Sensitivity Level: 1 AEC-Q200 Qualified 303.825 MHz SAW Resonator Compliant The RO3104E-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.

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.
