• Standardized 4-pad footprint for SMD assembly compatibility
• Designed for general-purpose clock signal generation

Crystals Applications

• Microcontroller clock sources
• Digital logic timing circuits
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm exact mechanical dimensions and soldering profile requirements. Ensure that the 16pF load capacitance matches the target circuit design specifications. Confirm package orientation and pin assignment details prior to PCB layout finalization to prevent assembly errors.

Crystals Selection Notes

Select this component when a 12 MHz reference is required with moderate accuracy. The 80 Ohm ESR value should be compatible with the oscillator circuit's drive level constraints. Consider the ±100ppm tolerance against environmental temperature variations expected in the final application environment.

Crystals Part Context

This part belongs to the family of ceramic resonators and crystals manufactured by Geyer Electronic America, Inc. These components are utilized in frequency control products where cost-effective and compact solutions are prioritized over high-precision quartz alternatives. The 4-SMD form factor supports modern surface-mount technology manufacturing standards.

Crystals Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching electrical parameters including 12 MHz frequency, 16pF load capacitance, and 80 Ohm ESR within the same 4-SMD package type.
