416F3801XALT

Crystals Overview

The CTS-Frequency Controls 416F3801XALT is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 38 MHz with a frequency tolerance of ±10 ppm and a load capacitance of 12 pF. The component features an equivalent series resistance (ESR) of 60 Ohms and utilizes a 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm x 0.45mm maximum height. It supports a standard operating temperature range of -10°C to +60°C and is compliant with RoHS standards.

Crystals Feature Summary

• Fundamental mode operation for stable frequency generation
• Surface-mount 4-SMD No Lead packaging for automated assembly
• High stability with ±10 ppm initial frequency tolerance
• RoHS compliant construction for environmental safety

Crystals Applications

• Clock signal generation in microcontroller circuits
• Timing references for communication interfaces
• Frequency control in consumer electronic devices
• Oscillator circuits requiring precise 38 MHz reference

Crystals Procurement Notes

Verify the specific suffix 'ALT' against the manufacturer's current datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure the required ESR and load capacitance match the target oscillator circuit design. Confirm RoHS compliance status if restricted substances are a constraint for the final assembly. Cross-reference the package dimensions with PCB footprint libraries to ensure accurate placement during manufacturing.

Crystals Selection Notes

Select this component when a 38 MHz fundamental crystal is required in a compact 4-SMD form factor. The ±10 ppm tolerance suits applications needing moderate frequency accuracy without active trimming. Consider the 60 Ohm ESR to ensure proper oscillation startup in the chosen circuit topology. Verify that the -10°C to +60°C operating range aligns with the environmental conditions of the end product.

Crystals Part Context

This part belongs to the CTS 416 Series of surface-mount crystals, which are characterized by small footprints suitable for space-constrained designs. The series offers various frequencies and tolerances, with the 416F3801XALT representing a specific 38 MHz variant. These components are widely used in general-purpose electronics where reliable timing is essential but extreme precision or wide temperature ranges are not mandatory.

Crystals Replacement Considerations

Direct substitutes include the 416F3801XALR and 416F3801XAAR from CTS-Frequency Controls, provided the packaging format (tape vs. bag) and minor electrical parameter variations are acceptable. Other manufacturers may offer equivalent 38 MHz crystals in 4-SMD packages, but verification of ESR, load capacitance, and drive level is required to ensure circuit compatibility.
