The Geyer Electronic America, Inc. model 12.9501 is a surface-mount crystal oscillator (XO) designed for precise clock generation in electronic circuits. It utilizes a 4-SMD, no-lead package form factor to facilitate automated assembly and compact board layouts. The device operates within an industrial temperature range of -20°C to +70°C (-4°F to 158°F). It provides a frequency stability of 50 ppm, ensuring reliable timing synchronization for connected systems.
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage levels and output logic types. Confirm that the package dimensions match the intended PCB footprint. Check for any recent updates to the RoHS compliance status or lead-free specifications before finalizing procurement orders.
Select this component when a standard XO is required for applications needing moderate frequency stability. The 4-SMD package is suitable for space-constrained designs. Ensure the operating environment stays within the specified -20°C to +70°C range. Consider load capacitance requirements if interfacing with microcontrollers or FPGAs that do not have internal compensation.
This part belongs to Geyer Electronic's broad portfolio of quartz crystals and oscillators. The company specializes in frequency control products, including TCXOs and VCXOs, aimed at supporting accurate clock generation across various electronic markets. This specific model represents their surface-mount oscillator offerings.
Consult official substitution matrices for compatible alternatives. Verify pinout compatibility and electrical parameters such as supply voltage and output waveform before replacing.
