RO2125A-5 Ideal for 315 MHz Superhet Receivers Very Low Series Resistance Quartz Stability Surface-Mount, Ceramic Case with 21 mm2 Footprint Complies with Directive 2002/95/EC (RoHS) The RO2125A-5 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 local oscillators operating at approximately 304.3 MHz. This SAW is designed for 315 MHz superhet receivers with 10.7 MHz IF. Applications include automotive keyless-entry receivers operating in the USA under FCC Part 15, in Canada under DOC RSS-210, and in Italy. 304.3 MHz SAW Resonator Absolute Maximum Ratings Rating CW RF Power Dissipation DC Voltage Between Terminals Case Temperature Soldering Temperature (10 seconds / 5 cycles max.)
