445W22L27M00000

Crystals Overview

The CTS-Frequency Controls 445W22L27M00000 is a surface-mount quartz crystal resonator operating at a fundamental frequency of 27 MHz. It features a frequency tolerance of ±20 ppm and a load capacitance of 12 pF. The component is housed in a compact 2-SMD, no-lead package with dimensions of 5.00 mm x 3.20 mm and a maximum height of 1.35 mm. Designed for industrial applications, it operates within a temperature range of -20°C to +70°C. The unit exhibits an equivalent series resistance (ESR) of 40 Ohms and complies with RoHS3 standards.

Crystals Feature Summary

• Utilizes glass seal technology for enhanced environmental stability and reliability
• Optimized for space-constrained surface-mount circuit designs
• Provides stable oscillation performance across specified industrial temperature ranges

Crystals Applications

• Industrial control systems requiring precise timing references
• Communication equipment utilizing 27 MHz carrier frequencies
• Microcontroller clock sources in consumer electronics

Crystals Procurement Notes

Verify the specific suffix 'L' indicates the 12 pF load capacitance variant, as other suffixes in the 445W series denote different capacitance values such as 20 pF or 24 pF. Confirm that the required operating temperature range aligns with the -20°C to +70°C specification. Ensure the PCB footprint matches the 5.00 mm x 3.20 mm SMD package dimensions to guarantee proper solder joint formation and mechanical retention during assembly processes.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required with a strict 12 pF load capacitance requirement. Consider the 40 Ohm ESR value for oscillator circuit compatibility. Choose this part over ceramic resonators if higher frequency stability and lower aging rates are necessary for the application's long-term accuracy requirements.

Crystals Part Context

This component belongs to the CTS 445 Series, which specializes in glass-sealed surface-mount crystals. The series offers various load capacitance options identified by alphanumeric suffixes. The 445W22L27M00000 specifically addresses the need for compact, reliable timing solutions in modern electronic assemblies where board space is limited but performance standards remain high.

Crystals Replacement Considerations

Direct substitutes include the 445C22E27M00000 and 445A22E27M00000, though these variants typically feature a 20 pF load capacitance rather than 12 pF. Verify oscillator circuit design compatibility before swapping parts with different load capacitance specifications to prevent frequency drift.
