Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the load capacitance requirements of the host circuit match the component's rated value to maintain frequency accuracy. Check for any recent revisions in the product documentation regarding environmental compliance or material composition changes before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 48 MHz fundamental frequency is required in a small form factor. Ensure the application environment stays within the specified -20°C to +70°C range to guarantee the stated stability. Compare the ESR limits with the oscillator circuit's drive level capabilities to prevent over-driving the crystal. Consider the 18 pF load capacitance requirement when designing the surrounding circuitry to achieve precise timing performance.

Crystals Part Context

This model belongs to TXC's standard surface-mount crystal lineup, offering reliable performance for general-purpose timing needs. The 7B series is engineered for cost-effective mass production while maintaining strict frequency tolerances. It serves as a direct replacement for older through-hole or larger surface-mount crystals where space savings are critical. The component supports various industries requiring stable clock signals without complex external compensation.

Crystals Replacement Considerations

Consult official substitution lists for compatible alternatives with identical pinouts and electrical characteristics. Verify that any substitute part meets the same 48.000 MHz frequency and 18 pF load capacitance requirements. Ensure the replacement maintains the 3225 package dimensions for mechanical fit. Cross-reference stability and ESR specs to avoid performance degradation in sensitive timing circuits.
