Crystals Procurement Notes

Verify the specific suffix ID against the manufacturer's latest datasheet to confirm pinout and sealing specifications. Ensure the required frequency tolerance of ±30 ppm aligns with system timing budgets. Confirm RoHS compliance status if restricted substances are prohibited in the final assembly process.

Crystals Selection Notes

Select this component when a fundamental mode crystal with robust ceramic sealing is required for high-temperature environments. The 48 MHz frequency and 18 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR value for proper drive level management within the host application circuitry.

Crystals Part Context

This part belongs to the 402 series of CTS-Frequency Controls, which specializes in sealed ceramic crystals. The series is characterized by hermetic sealing and high Q-factor performance. It serves as a timing reference solution for applications demanding long-term stability and resistance to mechanical shock compared to standard epoxy-sealed units.

Crystals Replacement Considerations

Direct substitutes may include other 48 MHz fundamental mode crystals with identical 4-SMD dimensions and 18 pF load capacitance. Verify that alternative parts meet the same ±30 ppm tolerance and -40°C to +105°C temperature range requirements.
