12.88673 – GEYER ELECTRONIC

The GEY 12.88673 is a surface-mount crystal resonator packaged in a four-pad ceramic package. It is designed for frequency control applications requiring a stable and accurate timebase. The crystal is manufactured using quartz, exhibiting piezoelectric properties for electromechanical resonance. The specified frequency of 12.88673 MHz indicates the crystal’s fundamental mode of operation. Electrical connection is achieved through the four pads, typically connected to an oscillator circuit within a microcontroller or other timing device. The ceramic package provides mechanical protection and environmental stability for the quartz crystal element. Key electrical characteristics, such as series resistance (ESR), load capacitance (CL), and frequency tolerance, are critical for proper circuit design and must be considered in conjunction with the oscillator circuit parameters to ensure optimal performance and frequency accuracy.
