Crystals Procurement Notes

Verify the specific suffix 'EII' against official TXC documentation to confirm exact mechanical and electrical specifications, as datasheets may vary slightly between similar variants like MEEQ or METI. Ensure compatibility with reflow soldering profiles specified in the manufacturer's handling guidelines. Confirm that the 10pF load capacitance matches the oscillator circuit design requirements before procurement.

Crystals Selection Notes

Select this component when a 30 MHz reference with ±10 ppm stability is required in a small SMD form factor. The 60 Ohm ESR must align with the oscillator circuit's drive level constraints. Consider the -20°C to +70°C temperature range against the operational environment. Verify that the seam-sealed package meets the mechanical durability needs of the target application compared to non-sealed alternatives.

Crystals Part Context

This part belongs to the TXC 7M series of miniature quartz crystals. The series is characterized by high precision and reliability, utilizing seam sealing technology to protect the resonator element. These components are designed for surface-mount technology (SMT) integration, offering a balance between performance and board space efficiency for modern electronic designs requiring stable frequency sources.

Crystals Replacement Considerations

Direct substitutes include the 7M-30.000MEEQ-T and 7M-30.000METI-T, provided they meet the same 30 MHz, 10pF, and ±10 ppm specifications. Verify package dimensions and pin compatibility before substitution. Cross-reference with other manufacturers' 3225-sized 30 MHz crystals if supply chain constraints require alternative sourcing.
