Crystals Procurement Notes

Verify the specific suffix codes against official Meritek documentation to confirm exact electrical parameters such as load capacitance and frequency tolerance. Ensure the ordering information matches the required package dimensions and operating temperature range. Cross-reference datasheet revisions to validate compliance with current RoHS standards and material specifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is required within a limited board space. The 15 pF load capacitance must align with the oscillator circuit design. Consider the -20 °C to +70 °C temperature range against environmental conditions. The 50 ppm tolerance suits general timing applications where higher precision is not critical.

Crystals Part Context

This part belongs to the MX3 series of ceramic SMD crystals from Meritek Electronics. The series utilizes seam-sealed ceramic packages designed for surface mount technology. These components are engineered for applications requiring reliable frequency control in compact electronic assemblies, distinguishing them from larger through-hole or metal can variants.

Crystals Replacement Considerations

MX3KJJC20M0: Offers identical 20 MHz frequency but differs in load capacitance (32 pF) and operating temperature range (-40 °C to +85 °C). Verify circuit compatibility regarding load capacitance changes before substitution.
