402F19212IAR

Crystals Overview

The CTS-Frequency Controls 402F19212IAR is a surface-mount MHz crystal designed for frequency control applications. It operates at a nominal frequency of 19.2 MHz with a frequency tolerance of ±10ppm and stability of ±20ppm. The component features a load capacitance of 10pF and an equivalent series resistance (ESR) of 120 Ohms. It utilizes a 4-SMD, no lead package with dimensions of 2.00mm x 1.60mm x 0.55mm. The device supports fundamental mode operation and functions within a temperature range of -40°C to 85°C.

Crystals Procurement Notes

Verify the specific suffix 'IAR' against the manufacturer's current production status, as availability may vary. Confirm that the 10pF load capacitance matches the target circuit requirements. Ensure the 120 Ohm ESR is compatible with the oscillator driver strength. Check for any recent obsolescence notices or lifecycle changes from CTS-Frequency Controls before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required with tight ±10ppm initial tolerance. The 10pF load capacitance dictates compatibility with specific MCU or oscillator pin configurations. The 4-SMD footprint requires adequate PCB space for the 2.00mm x 1.60mm outline. Consider the 120 Ohm ESR for drive level sensitivity in low-power designs.

Crystals Part Context

This part belongs to the CTS 402 Series of standard crystals. It shares the same physical package and general electrical characteristics with variants like 402F19212ILT and 402F19212IKR, differing primarily in packaging type or specific tolerance grades. The series provides a standardized solution for embedded timing needs.

Crystals Replacement Considerations

Direct substitutes include 402F19212ILT and 402F19212IKR from CTS-Frequency Controls. These parts share identical electrical parameters and mechanical dimensions, allowing for potential form-fit-function replacements if supply constraints exist.
