RO3104C-1

AEC-Q200 This component was always RoHS compliant from the first date of manufacture. • • • • • RO3104C-1 Ideal for 303.825 MHz Transmitters Very Low Series Resistance Quartz Stability Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 RoHS 303.825 MHz SAW Resonator Compliant The RO3104C-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 local oscillators operating at approximately 303.825 MHz. This SAW was designed for AM transmitters in automotive-keyless-entry applications operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.

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.
