403C35D16M38400

Crystals Overview

The CTS-Frequency Controls 403C35D16M38400 is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 16.384 MHz with a frequency tolerance of ±30ppm and stability of ±50ppm over the operating temperature range. The component features a load capacitance of 18pF and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a maximum height of 0.85mm. The device supports operation between -20°C and +70°C and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental mode quartz crystal resonator providing stable frequency generation
• Surface-mount design in a compact 4-SMD no-lead package
• Compliant with RoHS3 environmental regulations

Crystals Applications

• General-purpose clock signal generation in electronic circuits
• Microcontroller and processor system timing references
• Communication interface synchronization modules

Crystals Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 16.384 MHz frequency, 18pF load capacitance, and 80 Ohm ESR. Confirm the package dimensions align with the PCB footprint requirements. Ensure the operating temperature range of -20°C to +70°C meets the application's thermal constraints. Check for RoHS3 compliance if environmental regulations are mandatory for the final product assembly.

Crystals Selection Notes

Select this component when a fundamental mode crystal with a 16.384 MHz output is required for surface-mount assembly. The 18pF load capacitance must match the oscillator circuit design specifications. Consider the ±30ppm tolerance and ±50ppm stability limits against the system's jitter and accuracy requirements. The 4-SMD package offers a smaller form factor compared to through-hole alternatives, suitable for high-density board layouts.

Crystals Part Context

This component belongs to the CTS-Frequency Controls crystal resonator family, specifically designed for standard surface-mount integration. It serves as a passive frequency-determining element within active oscillator circuits or microcontroller clock inputs. The 4-SMD no-lead configuration distinguishes it from older leaded packages, facilitating automated pick-and-place manufacturing processes while maintaining reliable performance in consumer and industrial electronics.
