Crystals Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and terminal finish specifications. Confirm that the selected variant matches the required load capacitance and frequency tolerance for the target application. Check current availability status as supply levels may fluctuate. Ensure compatibility with standard reflow soldering profiles defined for 4-SMD packages. Validate regulatory compliance requirements such as RoHS3 for the intended market.

Crystals Selection Notes

Select this component when a 48 MHz fundamental frequency with ±10 ppm stability is required. Consider the 9 pF load capacitance and 60 Ohm ESR values for oscillator circuit design. Choose this part for applications requiring a small 2.00mm x 1.60mm footprint. Ensure the operating temperature range of -20°C to +70°C meets environmental constraints. Verify that the surface-mount package type aligns with PCB layout capabilities.

Crystals Part Context

This component belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and package options for general-purpose timing applications. The 402F48011CJR specifically addresses needs for 48 MHz clock signals in space-constrained designs.
