Crystals Procurement Notes

Verify the specific package variant and load capacitance requirements against your circuit design before ordering. Confirm that the 2-SMD no-lead form factor aligns with your PCB layout constraints. Ensure compatibility with the specified 16 pF load capacitance to maintain the stated ±50 ppm frequency accuracy. Check for any recent supply chain advisories regarding lead times from the manufacturer.

Crystals Selection Notes

Select this component when a compact 8.0 MHz reference signal is required for miniaturized audio or wireless devices. The 100 Ohm series resistance and 16 pF load capacitance define the electrical interface for the oscillator circuit. Consider the physical dimensions of the 2-SMD no-lead package to ensure adequate clearance on the printed circuit board during the layout phase.

Crystals Part Context

This part belongs to the KX-2 series of quartz crystals manufactured by Geyer Electronic America, Inc. The series is characterized by its small physical size, making it distinct from standard through-hole or larger surface-mount crystals. It serves as a passive frequency-determining element within active oscillator circuits used in consumer electronics.

Crystals Replacement Considerations

Direct substitutes must match the 8.0 MHz frequency, 16 pF load capacitance, and 2-SMD no-lead package. Verify that alternative components meet the same ±50 ppm tolerance and 100 Ohm series resistance specifications to ensure circuit performance parity.
