402F40033CLR

Crystals Overview

The CTS-Frequency Controls 402F40033CLR is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 40.0000 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms. The component features a frequency tolerance of ±30 ppm and stability of ±30 ppm across an operating temperature range of -20°C to +70°C. Housed in a compact 4-SMD, No Lead package measuring 2.00mm x 1.60mm with a maximum height of 0.55mm, it supports automated assembly processes.

Crystals Feature Summary

• Fundamental resonance mode operation for stable frequency generation
• Compact 4-SMD no-lead package suitable for high-density PCB layouts
• RoHS compliant construction meeting environmental standards

Crystals Applications

• Clock signal generation in digital logic circuits
• Microcontroller and microprocessor system timing
• Communication interface synchronization

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 varying stock levels or obsolescence notices. Ensure the ordering part number matches the exact electrical specifications required for the target application circuit design.

Crystals Selection Notes

Select this component when a 40 MHz fundamental crystal with 12 pF load capacitance is required for space-constrained designs. The 60 Ohm ESR must be compatible with the oscillator circuit's drive level requirements. Consider the ±30 ppm tolerance for general-purpose timing applications where higher precision is not critical.

Crystals Part Context

This part belongs to the 402 series of SMD crystals from CTS-Frequency Controls, characterized by small footprints like 2.0mm x 1.6mm. It serves as a surface-mount alternative to through-hole HC-49 packages, enabling lower profile assemblies in consumer electronics and industrial control systems requiring reliable clock sources.

Crystals Replacement Considerations

Direct substitutes include 402F40033CAT and 402F40033CLT. Verify that any replacement maintains identical frequency, load capacitance, ESR, and package dimensions to ensure mechanical and electrical compatibility within the existing circuit design.
