Crystals Procurement Notes

Verify that the required load capacitance matches the circuit design, as this component specifies 7 pF. Confirm the ESR of 80 Ohms aligns with oscillator driver strength requirements. Ensure the HC-49/US package dimensions fit the PCB layout constraints. Check that the ±10 ppm frequency tolerance meets the system's timing precision needs before finalizing procurement.

Crystals Selection Notes

Select this part when a 6.7458 MHz frequency is specifically required for the application. Consider the 7 pF load capacitance requirement to ensure proper oscillator operation. Evaluate the HC-49/US package size against available board space. Assess whether the ±10 ppm stability is sufficient for the intended timing accuracy compared to higher-grade alternatives.

Crystals Part Context

This component belongs to the quartz crystal resonator category produced by Suzhou Hangjing Elec&Tech Co., Ltd.
