Crystals Procurement Notes

Verify the specific lot date code and manufacturing origin upon receipt to ensure compliance with quality standards. Confirm that the received components match the specified 48 MHz frequency and ±10 ppm tolerance. Check for physical integrity of the SMD leads. Ensure storage conditions prevent moisture absorption prior to soldering. Review any recent distributor notices regarding potential shipping delays due to order volume fluctuations.

Crystals Selection Notes

Select this component when a 48 MHz reference signal is required in ultra-compact form factors. The ±10 ppm tolerance offers higher precision than standard ±30 ppm variants. Consider the 6 pF load capacitance requirement for circuit matching. The 50 Ohm ESR impacts drive level sensitivity; ensure the oscillator circuit provides appropriate power. Evaluate the 4-SMD package dimensions against PCB real estate constraints.

Crystals Part Context

This crystal belongs to the KX-2 series from Geyer Electronic America, Inc., which specializes in frequency control products. The series targets miniaturized consumer electronics where size is critical. As a Class III Life Supporting Device, it is used in systems where failure could impact safety or health, necessitating high reliability.
