RO3101D

RO3101D • • • • • • • Ideal for European 433.92 MHz Remote Control and Security Transmitters Very Low Series Resistance Quartz Stability Complies with Directive 2002/95/EC (RoHS) Tape and Reel Standard per ANSI/EIA-481 Moisture Sensitivity Level: 1 AEC-Q200 Qualified RoHS 433.92 MHz SAW Resonator Compliant The RO3101D 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.

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.
