The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.20 mm x 2.50 mm and a maximum height of 0.030 inches (0.75 mm). The device supports a commercial operating temperature range from -20°C to +70°C and is supplied in tape and reel packaging.

Crystals Feature Summary

• Fundamental mode quartz crystal operation for precise timing
• Surface-mount design compatible with automated assembly processes
• Commercial grade temperature range suitability for general electronics
• RoHS 3 compliant construction for environmental standards

Crystals Applications

• Wireless infrastructure timing circuits
• Wireline core networking synchronization modules
• General embedded communication systems requiring stable clock references

Crystals Procurement Notes

Verify the specific package variant against the datasheet, as the model number indicates a 3.2x2.5mm footprint, which differs from similar 405 series parts. Confirm that the application circuit matches the 10pF load capacitance requirement to ensure accurate oscillation frequency. Check for RoHS 3 compliance status if required by regional regulations. Ensure the supply chain source provides genuine CTS-Frequency Controls components to guarantee specified ESR and stability parameters are met during production.

Crystals Selection Notes

Select this component when a 14.4 MHz fundamental frequency is required in a small surface-mount footprint. The 60 Ohm ESR value must be compatible with the oscillator circuit's drive level specifications to prevent overdriving the crystal. Consider the ±10 ppm stability for applications where moderate frequency accuracy is sufficient. The commercial temperature range limits usage in extreme environmental conditions compared to industrial grade alternatives.

Crystals Part Context

This component belongs to the CTS 403 series of surface-mount crystals, characterized by a 3.2x2.5mm package size. It serves as a timing reference element within larger electronic assemblies, providing the necessary resonance for microcontrollers or communication interfaces. The series offers various frequency options tailored for consumer and industrial electronics requiring reliable clock signals without the complexity of active oscillators.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include 403C11J14M40000 and 405C11A14M40000 from CTS-Frequency Controls. Cross-manufacturer replacements such as ECS-144-9-42-CKM-TR may require verification of mechanical footprint and electrical parameter alignment.
