Crystals Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations exist between tape-and-reel and tube formats. Confirm that the required frequency tolerance aligns with system requirements, noting the distinction between normal temperature tolerance and overall stability specifications. Ensure compatibility with the target load capacitance of 18 pF in the circuit design.

Crystals Selection Notes

Select this component when a precise 48 MHz reference is required in space-constrained designs. The 18 pF load capacitance must match the oscillator circuit's external capacitors to maintain accuracy. Consider the ±10 ppm tolerance for standard timing applications, while acknowledging the ±15 ppm overall stability limit for wider temperature ranges compared to higher-grade alternatives.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. It shares the same footprint and electrical characteristics with variants such as the 402F4801XIDT, differing primarily in packaging format. The series is designed for general-purpose timing applications requiring reliable performance in consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include the 402F4801XIDT, which offers identical electrical specifications but may differ in packaging. Cross-reference with other manufacturers' 48 MHz SMD crystals ensuring matching 18 pF load capacitance and 60 Ohm ESR values.
