Crystals Procurement Notes

Verify the specific load capacitance requirement matches the target circuit design, as this component is specified at 8pF. Confirm that the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the end application. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout specifications before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a compact surface-mount crystal is required for 40.5MHz applications. Consider the ±20ppm tolerance if higher precision is not critical. Evaluate the 60 Ohm series resistance against the oscillator circuit's drive level requirements to ensure stability and prevent over-driving the crystal element during operation.

Crystals Part Context

This part belongs to the 7V series of ultra-miniature crystals from TXC Corporation. The series is characterized by thin profiles and low series resistance, designed for high Q-factor performance.
