Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design before procurement. Confirm that the operating temperature range meets the environmental specifications of the end application. Ensure compatibility with standard surface mount reflow soldering profiles to maintain component integrity during assembly processes.

Crystals Selection Notes

Select this component when a compact footprint is required for high-frequency timing applications. The 60 Ohm ESR value suits oscillator circuits designed for low power consumption. Consider the ±15ppm stability limit for systems requiring precise clock synchronization without external temperature compensation.

Crystals Part Context

This part belongs to the 402 Series of surface mount crystals from CTS-Frequency Controls. The series provides various frequency options and package sizes optimized for modern PCB layouts. The 402F480XXCJR specifically addresses the demand for reliable 48 MHz timing sources in space-constrained digital electronics.

Crystals Replacement Considerations
