Electrical Characteristics

www.RFM.com E-mail: info@rfm.com

• Ideal for 418 MHz Transmitters

• Very Low Series Resistance

• Quartz Stability

• Rugged, Hermetic, Low-Profile TO39 Case

• Complies with Directive 2002/95/EC (RoHS)

The RO3103 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 418.0 MHz. The RO2103 is designed specifically for remote-control and wireless security transmitters

operating in the United Kingdom under dTI MPT 1340 and in the USA under FCC Part 15.
