Crystals Procurement Notes

Verify the specific suffix E against D against manufacturer documentation to confirm exact tolerance and aging specifications. Ensure circuit design accounts for the 18pF load capacitance requirement. Confirm that the 4-SMD footprint matches the target PCB layout dimensions precisely before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 7.3728 MHz reference is required in a compact SMD form factor. The ±30 ppm tolerance suits applications needing moderate precision without the cost of an oscillator. Verify that the operating environment remains within the specified -20°C to +70°C range for optimal performance.
