402F40012IAR

Crystals Overview

The CTS-Frequency Controls 402F40012IAR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 40 MHz. It features a frequency tolerance of ±10 ppm and a load capacitance of 10 pF. The component exhibits an equivalent series resistance (ESR) of 60 Ohms and is housed in a compact 4-SMD, no-lead package with dimensions of 2.00 mm x 1.60 mm. Designed for stability, it maintains a frequency stability of ±20 ppm and operates within a temperature range starting from -40°C.

Crystals Feature Summary

• Provides precise timing signals via fundamental mode operation
• Ensures high frequency accuracy with tight tolerance specifications
• Supports automated assembly through leadless surface-mount packaging

Crystals Applications

• Clock generation circuits in digital systems
• Microcontroller oscillator inputs
• Communication interface timing references

Crystals Procurement Notes

Verify the specific suffix 'IAR' against official CTS documentation to confirm tape-and-reel packaging and exact load capacitance parameters. Ensure compatibility with target PCB footprint dimensions of 2.00mm x 1.60mm. Cross-reference datasheet revisions for any updates to environmental compliance or thermal characteristics prior to final design approval.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±10 ppm initial tolerance is required. Consider the 10 pF load capacitance requirement for circuit matching. Evaluate the 60 Ohm ESR against driver strength limitations. Confirm that the -40°C minimum operating temperature aligns with the intended application environment constraints.

Crystals Part Context

This part belongs to the 402 Series of SMD crystals from CTS-Frequency Controls. These components are designed for general-purpose timing applications requiring small form factors. The series offers various frequency options and load capacitances to suit different oscillator circuit designs while maintaining standard surface-mount compatibility.

Crystals Replacement Considerations

Direct substitutes include the 402F40012ILT and 402F40012ILR variants from the same manufacturer. Verify that alternative suffixes match the required load capacitance and packaging format. Ensure that any cross-brand replacement meets identical electrical parameters including frequency, tolerance, and ESR values.
