402F1601XIDT

Crystals Overview

The CTS-Frequency Controls 402F1601XIDT is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 16 MHz with a frequency tolerance of ±10 ppm and a stability of ±15 ppm over the operating temperature range. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 120 Ohms. It utilizes a hermetic ceramic package in a 4-SMD, no-lead configuration with dimensions of 2.0 mm x 1.6 mm x 0.55 mm. The device supports operation from -40°C to +85°C and is supplied in tape and reel packaging compliant with EIA-418 standards.

Crystals Feature Summary

• Hermetic ceramic surface mount package ensuring environmental reliability
• Fundamental AT-cut crystal design for stable oscillation
• Sub-miniature form factor suitable for high-density PCB layouts

Crystals Applications

• High-frequency clock generation in digital systems
• Microcontroller and processor timing references

Crystals Procurement Notes

Verify component availability status as distribution channels may list discontinued or end-of-life items. Confirm that the specific ordering suffix matches the required tolerance and packaging specifications. Ensure compatibility with existing PCB footprint and reflow soldering profiles defined by the manufacturer datasheet before integration into production.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency with ±10 ppm tolerance is required. The 18 pF load capacitance must match the oscillator circuit design. Consider the 120 Ohm ESR for drive level limitations. The hermetic package offers superior protection compared to standard epoxy-sealed alternatives in harsh environments.

Crystals Part Context

This part belongs to the CTS 402 Series, which provides sub-miniature surface-mount crystals. The series covers frequencies from 16 MHz to 96 MHz with various tolerance options. The 402F1601XIDT specifically addresses the need for compact, reliable timing solutions in space-constrained electronic designs requiring fundamental mode operation.

Crystals Replacement Considerations

Direct substitutes within the same series include parts with identical frequency and package but different tolerances, such as 402F160XXCDR variants. Verify electrical parameters like ESR and load capacitance before substitution to ensure circuit stability.
