402F54022IKR

Crystals Overview

The CTS-Frequency Controls 402F54022IKR is a fundamental mode MHz crystal resonator operating at a nominal frequency of 54 MHz. It features a load capacitance of 8 pF and a frequency tolerance/stability of ±20 ppm. The component exhibits an equivalent series resistance (ESR) of 60 Ohms. It is housed in a 4-SMD, no-lead package with dimensions of 2.00mm x 1.60mm and a maximum seated height of 0.55mm. The device supports surface mount installation and operates within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Fundamental oscillation mode for stable clock signal generation
• Compact 4-SMD no-lead surface mount footprint
• Wide industrial operating temperature range capability

Crystals Applications

• Precision timing circuits requiring 54 MHz reference
• Embedded system clock sources
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix IKR against official CTS documentation to confirm the 8pF load capacitance specification, as other suffixes in the 402 series may differ. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected variant matches the required PCB land pattern for 4-SMD no-lead packages.

Crystals Selection Notes

Select this component when a 54 MHz fundamental crystal with 8pF load capacitance is required. Compare ESR values against oscillator circuit requirements to ensure adequate drive level margins. Verify that the ±20ppm stability meets the system timing accuracy constraints. Ensure the operating temperature range covers the intended environmental conditions.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals. The series offers various frequencies and package sizes optimized for space-constrained designs. The 402F54022IKR specifically targets applications needing a 54 MHz output in a small form factor. It is distinct from variants with different load capacitances or package styles within the same family.

Crystals Replacement Considerations

Direct substitutes include 402F54022ILR and 402F54022IAR from CTS-Frequency Controls. These parts share identical electrical parameters but may differ in packaging or supply chain availability. Verify pin compatibility and mechanical dimensions before substitution.
