RO3101E-11

RO3101E-11 • • • • • Designed for European 433.92 MHz Remote Control and Security Transmitters Very Low Series Resistance Quartz Stability RoHS Complies with Directive 2002/95/EC (RoHS) Compliant Tape and Reel Standard per ANSI/EIA-481 433.92 MHz SAW Resonator The RO3101E-11 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 regulations.

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.
