402F19222IAR

Crystals Overview

The CTS-Frequency Controls 402F19222IAR is a surface-mount fundamental mode crystal oscillator operating at 19.2 MHz. It features a frequency stability and tolerance of ±20ppm, with a load capacitance of 10pF and an equivalent series resistance (ESR) of 120 Ohms. The component utilizes a 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm and a maximum seated height of 0.55mm. It operates within a temperature range of -20°C to 70°C and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental mode operation for precise frequency generation
• Standard 2.0mm x 1.6mm seam-welded SMD package design
• RoHS3 compliant environmental construction

Crystals Applications

• Digital clock signal generation in embedded systems
• Microcontroller clock sources
• Communication interface timing circuits

Crystals Procurement Notes

Verify the specific load capacitance and ESR requirements against the target circuit design before integration. Confirm that the operating temperature range meets the environmental conditions of the final application. Ensure compatibility with standard reflow soldering profiles for 4-SMD packages to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required with ±20ppm stability. The 10pF load capacitance must match the oscillator circuit's external capacitors. Consider the 120 Ohm ESR limit for driving capability. The compact 2x1.6mm footprint suits space-constrained PCB layouts requiring surface-mount technology.

Crystals Part Context

This part belongs to the CTS 402 Series, which covers frequencies from 16MHz to 60MHz. The series uses a standardized seam-welded package design. The 402F19222IAR variant specifically targets the 19.2 MHz common baud rate frequency used in serial communications and digital logic timing applications.

Crystals Replacement Considerations

Cross-reference with other 402 series variants such as 402F19222IJT or 402F19222IKT if different packaging quantities are needed. Verify that substitute parts maintain identical electrical parameters including 19.2 MHz frequency, 10pF load capacitance, and 120 Ohm ESR.
