CX5Z-A2B2C5-40-10.0D18

Crystals Overview

The CX5Z-A2B2C5-40-10.0D18 is a parallel fundamental quartz crystal resonator manufactured by Cardinal Components Inc. It operates at a nominal frequency of 10.0 MHz with a frequency tolerance of ±20 ppm and stability of ±50 ppm. The device features an 18 pF load capacitance and a maximum equivalent series resistance (ESR) of 40 Ohms. Designed for surface mount applications, it utilizes a 4-SMD, no-lead ceramic package measuring 7.00 mm in length, 5.00 mm in width, and 1.40 mm in height. The component supports a standard operating temperature range from -20°C to +70°C.

Crystals Procurement Notes

Verify the specific load capacitance requirement against the host circuit design to ensure accurate oscillation frequency. Confirm that the operating temperature range meets the environmental conditions of the final application. Check for RoHS compliance documentation if regulatory adherence is required. Ensure the footprint matches the 4-SMD no-lead package dimensions provided in the datasheet.

Crystals Selection Notes

Select this component when a 10 MHz fundamental frequency with ±20 ppm tolerance is required. Consider the 40 Ohm ESR limit for oscillator drive level compatibility. Evaluate the 7.0 x 5.0 mm package size against available board space constraints. Compare performance requirements against other CX5 series variants if different temperature ranges or frequencies are needed.

Crystals Part Context

This part belongs to the Cardinal Components CX5 series of ceramic surface mount crystals. The series offers various frequency options and package sizes, including 2-pad and 4-pad configurations. The CX5Z suffix indicates tape and reel packaging availability. This specific model represents a standard commercial grade variant within the broader portfolio of quartz resonators.

Crystals Replacement Considerations

Direct substitutes may include other 10 MHz, 18 pF, 4-SMD crystals from Cardinal Components or compatible manufacturers. Verify pinout compatibility and physical dimensions before substitution. Cross-reference electrical parameters such as ESR and stability to ensure circuit performance remains unchanged.
