LP049F35IET

Crystals Overview

The LP049F35IET is a surface-mount quartz crystal manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 6.144 MHz with a load capacitance of 20pF and a frequency tolerance of ±30ppm. The component utilizes an HC-49/US-SM package, measuring 11.10mm in length, 4.83mm in width, and 3.20mm in maximum height. It features an equivalent series resistance (ESR) of 40 Ohms and supports a base mode operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Surface-mount design utilizing the HC-49/US-SM package for automated assembly compatibility.
• Fundamental resonance mode operation providing stable frequency generation.
• Compliance with RoHS3 directives and REACH regulations for environmental standards.

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Embedded system oscillators

Crystals Procurement Notes

Verify the specific suffix 'IET' against official CTS documentation to confirm tape-and-reel packaging and lead composition. Ensure the selected variant matches the required operating temperature range and load capacitance specifications for the target circuit design prior to ordering.

Crystals Selection Notes

Select this component when a 6.144 MHz fundamental frequency is required in a compact surface-mount form factor. Consider the 20pF load capacitance requirement and ±30ppm initial tolerance. Verify that the 40 Ohm ESR aligns with the oscillator circuit's drive level constraints.

Crystals Part Context

This part belongs to the ATSSMLP (LP) Series from CTS-Frequency Controls. It shares the HC-49/US-SM footprint with other variants in the series but differs in frequency code and electrical parameters. It serves as a standard passive frequency control element for general-purpose electronic applications.

Crystals Replacement Considerations

LP049F35CDT and LP049F35CET are documented parameter equivalents from CTS-Frequency Controls. Cross-reference package variations and suffix definitions before substitution.
