Crystals Procurement Notes

Verify the specific ordering suffix and frequency tolerance requirements against your circuit design specifications before procurement. Ensure that the load capacitance matches the oscillator circuit's input capacitance to maintain accuracy. Confirm RoHS compliance status if environmental regulations apply to your production line. Check the active product status to guarantee long-term availability and supply chain stability for ongoing manufacturing needs.

Crystals Selection Notes

Select this component when a fundamental frequency crystal is required for 18.432 MHz applications with moderate stability needs. Consider the 70 Ohm ESR value to ensure compatibility with the driving circuit's power requirements. Evaluate the 8pF load capacitance against the host system's parasitic capacitance to avoid frequency deviation. Assess the thermal range against the intended operational environment to prevent performance degradation under extreme conditions.
