12.86612

Crystals Overview

The Geyer Electronic America, Inc. model 12.86612 is a fundamental frequency quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 12 MHz with a specified load capacitance of 10 pF and an equivalent series resistance (ESR) of 150 Ohms. The component features a tolerance of ±30 ppm to ensure stable clock generation in timing circuits. It is housed in a compact 4-SMD, No Lead package, facilitating automated assembly and integration into space-constrained electronic designs requiring precise frequency control.

Crystals Feature Summary

• Fundamental mode quartz crystal operation for stable frequency reference
• Surface-mount compatible 4-SMD no-lead package design
• Optimized for low equivalent series resistance applications

Crystals Applications

Crystals Procurement Notes

Verify the specific datasheet revision and exact mechanical dimensions against the manufacturer's official documentation before finalizing the design. Ensure that the load capacitance requirements of the host circuit match the 10 pF specification to maintain frequency accuracy. Confirm that the ±30 ppm tolerance meets the system's stability requirements under all operating temperature conditions.

Crystals Selection Notes

Select this component when a fundamental frequency crystal is required for 12 MHz applications with moderate stability needs. The 10 pF load capacitance suits standard CMOS logic interfaces. Consider the 150 Ohm ESR limit to ensure reliable oscillation startup in the target oscillator circuit topology without requiring excessive drive levels.
