Description

Ideal for 310.0 MHz Transmitters Very Low Series Resistance Quartz Stability Surface-Mount Ceramic Case with 21 mm2 Footprint Complies with Directive 2002/95/EC (RoHS)

The RO2053A-1 is a one-port, surface-acoustic-wave (SAW) resonator in a surface-mount ceramic case. It provides reliable, fundamental-mode, quartz frequency stabilization of local oscillatiors operating at 310 MHz. Applications include automotive keyless entry receivers operating in the USA under FCC Part 15 and in Canada under DoC RSS-210.
