402F54022ILR

Crystals Overview

The CTS-Frequency Controls 402F54022ILR is a surface-mount MHz crystal designed for precision timing applications. It operates at a nominal frequency of 54.0000 MHz with a frequency stability and tolerance of ±20ppm. The component features a load capacitance of 12pF and an equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 2.00mm x 1.60mm x 0.55mm maximum height. Operating within a temperature range of -40°C to 85°C, it supports base harmonic operation modes.

Crystals Feature Summary

• Provides master clock reference signals for microcontrollers, system-on-chip devices, and field-programmable gate arrays.
• Low equivalent series resistance facilitates oscillator startup and extends negative resistance margin.
• RoHS3 compliant construction ensures environmental safety standards are met.

Crystals Applications

• Master clock reference for MCU devices
• Timing source for SoC devices
• Clock generation for FPGA devices

Crystals Procurement Notes

Verify the specific suffix 'ILR' against project requirements, as packaging or lead finish variations may exist within the 402 series. Confirm current availability status directly with the manufacturer or authorized distributors, as supply chain conditions change frequently. Ensure the selected variant matches the required 4-SMD footprint and electrical parameters for the target circuit design.

Crystals Selection Notes

Select this component when a 54 MHz reference is required for digital logic circuits. The 12pF load capacitance must match the oscillator circuit design specifications. Consider the 60 Ohm ESR value for impedance matching in low-power applications. Verify that the -40°C to 85°C operating range satisfies the environmental constraints of the final assembly.

Crystals Part Context

This part belongs to the CTS 402 Series, a line of surface-mount crystals. The series offers various frequencies and packages optimized for high-volume manufacturing. The 402F54022ILR specifically addresses the need for stable 54 MHz timing in compact electronic designs, serving as a direct replacement for older through-hole or larger SMD variants in modern PCB layouts.

Crystals Replacement Considerations

Direct substitutes include 402F54022ILT and 402F5401XILR from CTS-Frequency Controls. These parts share identical electrical characteristics and pin configurations, allowing for drop-in replacement without circuit redesign. Verify package compatibility before substitution.
