Crystals Procurement Notes

Verify the specific load capacitance (6 pF) and frequency tolerance (±30 ppm) against your circuit design requirements before ordering. Confirm that the KX-5T package dimensions align with your PCB layout constraints. Ensure the operating temperature range (-40°C to +85°C) meets your application's environmental conditions. Cross-reference the manufacturer datasheet for any recent updates to specifications or recommended soldering profiles.

Crystals Selection Notes

Select this component when a compact, high-reliability quartz crystal is required for audio or wireless devices. The KX-5T package offers a small form factor ideal for miniaturized electronics. Consider the ±30 ppm tolerance if tight frequency stability is not critical. Verify compatibility with the oscillator circuit's load capacitance requirements to ensure accurate frequency generation.

Crystals Part Context

This part belongs to the KX series of super ultra-miniature quartz crystals from Geyer Electronic. These components are engineered for applications where size is a primary constraint, such as wearable technology and portable audio devices. The series emphasizes long-term availability and consistent performance across various environmental conditions.

Crystals Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. When seeking alternatives, prioritize components with identical frequency (27.120 MHz), load capacitance (6 pF), and package type (KX-5T or equivalent SMD). Verify that any replacement meets the same temperature and tolerance specifications.
