Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency tolerance and load capacitance parameters. Confirm that the required operating temperature range aligns with the specified -20°C to +70°C limits. Check for any specific handling or storage requirements related to the surface-mount package type. Ensure compatibility with the target circuit's drive level specifications to prevent over-driving the crystal. Validate that the tape and reel packaging matches the assembly equipment capabilities.

Crystals Selection Notes

Select this component when a 48 MHz fundamental frequency with ±10 ppm stability is required for surface-mount designs. Consider the 18 pF load capacitance requirement for oscillator circuit matching. Evaluate the 60 Ohm ESR against the oscillator amplifier's capability. Assess the 2 mm x 1.6 mm footprint against available PCB space. Verify that the commercial temperature range meets the environmental constraints of the final application.

Crystals Part Context

This part belongs to the 402 series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for consumer electronics and industrial applications. Similar parts in the lineup may differ in frequency, package size, or stability ratings. The 402 series generally utilizes fundamental mode operation for standard timing needs. Other variants might offer wider temperature ranges or tighter tolerances.

Crystals Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 18 pF load capacitance, and 4-SMD no-lead package. Verify equivalent ESR values to ensure oscillator startup reliability. Check for identical frequency stability and temperature range specifications. Cross-reference pinout and mechanical dimensions for board compatibility. Consult manufacturer cross-reference guides for verified alternative part numbers.
