AEC-Q200 This component was always RoHS compliant from the first date of manufacture. RO3101A-20 Ideal for European 433.92 MHz Transmitters Very Low Series Resistance Pb Quartz Stability Surface-Mount Ceramic Case 433.92 MHz Passivation for Enhanced Reliability SAW Resonator Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 The RO3101A-20 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 433.92 MHz. This SAW is designed specifically for remote-control and wireless security transmitters operating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.

The two terminals Output are interchangeable and unnumbered. The callout +VDC NC indicates no internal connection. The NC pads C1 +VDC assist with mechanical positioning and stability. Terminal External grounding of the NC pads is L1 recommended to help reduce parasitic capacitance in the circuit.

The optimum land pattern is dependent on the circuit board assembly process P P which varies by manufacturer. The distance between adjacent land edges CW RF Power Dissipation = INCIDENT - REFLECTED should be at a maximum to minimize parasitic capacitance. Trace lengths from terminal lands to other components should be short and wide to Typical Application Circuits minimize parasitic series inductances.
