RFM products are now Murata products. RO2043 Designed for 303.875 MHz SAW Resonator Low Series Resistance 303.875 MHz Quartz Stability Pb Rugged, Hermetic, Low-Profile TO39 Case SAW Complies with Directive 2002/95/EC (RoHS) Resonator The RO2043 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It provides reliable, fundamental-mode quartz frequency stabilization of fixed-frequency transmitters operating at 303.825 MHz. The RO2043-1 is designed specitically for low-power AM transmitters on remote-control and wireless alarm applications operating in the USA under FCC Part15, in Japan, in Australia, in Korea, and elsewhere.

Observe precautions for handling. NOTES: 1. Frequency aging is the change in f with time and is specified at +65C or less. Aging may exceed the specification for prolonged temperatures above +65C. C Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years. 2. The center frequency, f , is measured at the minimum insertion loss point, IL , with the resonator in the 50 test system (VSWR 1.2:1). The shunt C MIN inductance, L , is tuned for parallel resonance with C at f . Typically, f or f is less than the resonator f . TEST O C OSCILLATOR TRANSMITTER C 3.

This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance C is the O static (nonmotional) capacitance between pin1 and pin 2 measured at low frequency (10 MHz) with a capacitance meter. The measurement includes case parasitic capacitance with a floating case. For usual grounded case applications (with ground connected to either pin 1 or pin 2 and to the case), add approximately 0.25 pF to C . O 2010-2014 by Murata Electronics N.A., Inc.
