RO3101C-11 Datasheet, PDF (1/2 Pages) Murata Manufacturing Co., Ltd. – 433.92 MHz SAW Resonator

• Ideal for European 433.92 MHz Remote Control and Security Transmitters
• Very Low Series Resistance
• Quartz Stability
• Complies with Directive 2002/95/EC (RoHS) _Pb
The RO3101C 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.

is the static (nonmotional) capacitance between the two terminals
measured at low frequency (10 MHz) with a capacitance meter. The
measurement includes parasitic capacitance with "NC” pads unconnected.
Case parasitic capacitance is approximately 0.05 pF. Transducer parallel
capacitance can by calculated as: C_P ≈ C_O - 0.05 pF.
