Crystals Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited supply constraints. Confirm that the required load capacitance matches the target circuit design specifications before procurement. Ensure compliance with RoHS directives for intended application environments.

Crystals Selection Notes

Select this component when a 27 MHz reference signal is required for applications compatible with the -20°C to +70°C operational range. Consider the 13 pF load capacitance requirement to ensure accurate frequency stability. Evaluate the 40 Ohm ESR against the oscillator circuit capabilities to guarantee reliable startup and operation.

Crystals Part Context

This part belongs to the TXC 7B series of surface-mount crystals. It serves as a basic timing element distinct from active oscillators, requiring an external driver circuit. The 5 mm x 3.2 mm footprint offers a balance between size and performance for general-purpose timing needs.
