Crystals Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact load capacitance and stability ratings. Ensure the ordering part number matches the required temperature grade and package variant. Cross-reference datasheet specifications with design requirements before procurement to avoid compatibility issues.

Crystals Selection Notes

Select this component when a 48 MHz fundamental frequency is required with ±30 ppm stability. Verify that the circuit design accommodates the 18 pF load capacitance and 50 Ohm ESR limits. Confirm that the operational environment falls within the -40°C to +85°C range and that the 3.2x2.5 mm footprint fits the PCB layout constraints.

Crystals Part Context

This model belongs to the 7M series of surface-mount crystals from TXC Corporation. The series offers various frequency options and package sizes designed for compact electronic applications. The 7M designation indicates a standard fundamental mode crystal optimized for general-purpose timing needs.

Crystals Replacement Considerations

The 7M-48.000MAHC-T is a documented alternative within the same series, featuring a 9 pF load capacitance instead of 18 pF. Circuit redesign may be necessary due to the difference in load capacitance values.
