Crystals Procurement Notes

Verify the exact datasheet version from Geyer Electronic America, Inc. to confirm current specifications. Ensure compatibility with your circuit's load capacitance requirements, specifically the 9 pF specification. Check for any recent updates to the RoHS or REACH compliance status. Confirm that the 4-SMD no-lead package matches your PCB footprint design. Cross-reference the ESR value of 150 Ohms with your oscillator circuit design constraints.

Crystals Selection Notes

Select this component when a stable 18.432 MHz reference is required for digital logic circuits. The ±10 ppm tolerance suits most general-purpose timing applications where high precision is not critical. Consider the 9 pF load capacitance requirement when designing the feedback network. The SMD form factor is ideal for automated assembly and space-constrained designs. Evaluate if the ESR of 150 Ohms aligns with your oscillator amplifier capabilities.
