Electrical Characteristics

www.RFM.com

• Ideal for 418 MHz Transmitters in the U.K. and U.S.

• Very Low Series Resistance

• Quartz Stability

• Surface-Mount, Ceramic Case with 21 mm

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

The RO2103A 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 418.0 MHz. This SAW is designed for remote-control and wireless security transmitters operating

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