403C35E29M49120

Crystals Overview

The CTS-Frequency Controls 403C35E29M49120 is a surface-mount fundamental mode quartz crystal resonator operating at 29.4912 MHz. It features a frequency tolerance of ±30ppm and stability of ±50ppm with a 20pF load capacitance. The component utilizes a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a maximum height of 0.75mm. Designed for industrial temperature ranges from -20°C to 70°C, it complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental mode operation ensures stable oscillation characteristics.
• Surface-mount design facilitates automated assembly processes.
• Compliant with RoHS3 environmental regulations.

Crystals Applications

• Digital signal processing controller clocking
• Real-time system timing references
• Industrial communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix 'E' indicates the 20pF load capacitance variant against the schematic requirements. Confirm that the 4-SMD (3.2x2.5) footprint matches the PCB land pattern dimensions precisely. Ensure the operating temperature range of -20°C to 70°C aligns with the target application environment constraints before finalizing the order.

Crystals Selection Notes

Select this component when a 29.4912 MHz frequency is required with moderate stability specifications. The 20pF load capacitance must match the oscillator circuit design parameters. Consider the physical size constraints of the 3.20mm x 2.50mm package relative to available board space. Verify compatibility with the intended surface-mount reflow soldering profile.

Crystals Part Context

This part belongs to the CTS 403 series of general-purpose quartz crystals. The series offers various frequencies and package sizes optimized for consumer and industrial electronics. The 403C35E29M49120 specifically addresses applications requiring precise timing at nearly 30 MHz within standard commercial temperature limits.

Crystals Replacement Considerations

Direct substitutes include 403C35D29M49120, which differs by having an 18pF load capacitance instead of 20pF. Other similar options may exist but require verification of electrical parameters such as ESR and frequency tolerance to ensure circuit compatibility.
