402F30711CLR

Crystals Overview

The CTS-Frequency Controls 402F30711CLR is a surface-mount crystal resonator operating at a fundamental frequency of 30.72 MHz. It features a load capacitance of 12 pF and offers a frequency tolerance and stability of ±10 ppm. The component utilizes a sealed ceramic package with a 4-SMD, no-lead footprint measuring 1.60 mm x 1.20 mm. It has an equivalent series resistance (ESR) of 80 Ohms and operates within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Sealed ceramic construction for environmental protection
• Fundamental mode operation for precise frequency control
• Compact 4-SMD surface mount design

Crystals Applications

• Clock generation in digital communication systems
• Frequency reference for microcontroller units
• Timing circuits in consumer electronics

Crystals Procurement Notes

Verify the specific suffix 'CLR' against the manufacturer's current datasheet to confirm availability status and lead times, as distribution channels may list obsolete or discontinued variants. Ensure the selected supplier provides valid RoHS compliance documentation matching the EAR99 classification. Cross-reference the 4-SMD package dimensions with PCB footprints prior to procurement to prevent assembly errors.

Crystals Selection Notes

Select this component when a 30.72 MHz fundamental frequency with ±10 ppm stability is required for space-constrained designs. The 12 pF load capacitance must match the oscillator circuit requirements. Consider the 80 Ohm ESR value for drive level sensitivity. Verify that the -20°C to +70°C operating range meets the application's thermal environment constraints compared to industrial grade alternatives.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls, designed for general-purpose timing applications. It shares the standard 4-SMD no-lead form factor common across the series, allowing for automated pick-and-place assembly. The series typically covers frequencies between 16 MHz and 60 MHz with various tolerance options.

Crystals Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 402F30711CAR. Both parts share identical electrical specifications and physical dimensions. Verify that the alternative packaging type does not impact the existing reflow soldering profile or handling procedures.
