407F35E016M0000

Crystals Overview

The CTS-Frequency Controls 407F35E016M0000 is a surface-mount quartz crystal resonator designed for general-purpose timing applications. It operates at a fundamental frequency of 16 MHz with a load capacitance of 20pF. The component features a frequency tolerance of ±30ppm and stability of ±50ppm, ensuring reliable clock signals. It utilizes a 4-SMD, no-lead package measuring 7.00mm x 5.00mm with a maximum height of 1.30mm. The equivalent series resistance (ESR) is specified at 40 Ohms. Operating within a temperature range of -20°C to +70°C, it supports base harmonic operation modes.

Crystals Feature Summary

• Surface-mount design in a compact 4-SMD no-lead package
• Fundamental mode quartz crystal operation
• Integrated enable/disable functionality not applicable; passive resonator type

Crystals Applications

• Microcontroller clock sources
• General-purpose digital timing circuits
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific package dimensions and lead-free status against the manufacturer datasheet before integration. Confirm that the 40 Ohm ESR matches the oscillator circuit requirements. Ensure the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the final assembly. Check for RoHS compliance documentation if required by project specifications.

Crystals Selection Notes

Select this component when a standard 16 MHz fundamental frequency crystal is required for cost-sensitive designs. The 20pF load capacitance is common for many microcontroller families. Consider the physical size of 7.00mm x 5.00mm for PCB layout constraints. Verify that the ±30ppm tolerance meets the system's jitter and accuracy requirements compared to higher-stability oscillators.

Crystals Part Context

This part belongs to the 407 series of SMD crystals from CTS-Frequency Controls. It serves as a passive timing element distinct from active oscillators like the 632L series. The 407 series typically offers a balance between performance and footprint, suitable for consumer electronics and industrial control boards where space is limited but high-frequency stability is not critical.

Crystals Replacement Considerations

Direct substitute: 425F39E016M0000. Note that the 425 series uses a smaller 2.5x2mm package compared to the 7x5mm package of the 407 series. Verify PCB land pattern compatibility before substitution. Other 16MHz 20pF crystals may require re-evaluation of ESR and load capacitance matching.
