Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly processes. Confirm that the 40 Ohm ESR aligns with the oscillator circuit's drive level requirements to prevent over-driving the crystal. Ensure the -20°C to +70°C industrial temperature range meets the operational environment specifications of the target application before finalizing procurement.

Crystals Selection Notes

Select this component when a fundamental mode crystal with low ESR is required for 14.7456 MHz applications. The 40 Ohm ESR distinguishes it from higher resistance variants, potentially offering better performance in specific circuit topologies. Compare the 12 pF load capacitance against the circuit's stray capacitance to ensure accurate frequency tuning. Consider the 7B series form factor for compatibility with existing footprint designs.
