Crystals Procurement Notes

Verify the specific suffix 'HE' against official TXC documentation to confirm exact load capacitance and tolerance specifications, as variations exist within the 7M series. Ensure the design accommodates the specified 100 uW maximum drive level to prevent frequency drift or damage. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 50 MHz applications with moderate stability needs. The 12 pF load capacitance must match the oscillator circuit requirements. Consider the -20°C to +70°C operating range against environmental conditions. Compare ESR values with other 7M variants if impedance matching is critical for the target application.

Crystals Part Context

This part belongs to the TXC 7M series of surface mount crystals, designed for general electronic equipment. The series offers various frequencies and packages, with the 7M-50.000 variant specifically targeting 50 MHz applications. The HE suffix denotes specific manufacturing parameters within this family line.

Crystals Replacement Considerations

The discontinued 7B-50.000MAAJ-T is listed as a similar replacement by distributors, though it differs in package size (5x3.2mm) and harmonic mode. Verify mechanical fit and electrical compatibility before substitution.
