445C3XF30M00000

Crystals Overview

The CTS-Frequency Controls part number 445C3XF30M00000 is a generic placeholder for the 445 Series glass-seal crystal. These components are MHz crystals with surface mount installation in a 2-SMD, No Lead package. The series typically operates at base resonance mode with frequency stability ranging from ±20ppm to ±30ppm and load capacitance values of 16pF or 18pF. Operating temperatures generally span -20°C to 70°C or -40°C to 85°C, depending on the specific suffix variant.

Crystals Feature Summary

• Glass-seal construction for enhanced environmental durability
• Surface mount design compatible with automated assembly
• Base harmonic operation mode for fundamental frequency generation

Crystals Applications

• General purpose clock signal generation
• Microcontroller system timing references
• Industrial control circuit oscillators

Crystals Procurement Notes

Verify the exact alphanumeric suffix following '445C3X' to identify specific electrical parameters such as load capacitance, frequency tolerance, and temperature range. Generic ordering may result in receiving variants with differing performance characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before finalizing procurement orders.

Crystals Selection Notes

Select specific variants within the 445 series based on required load capacitance matching the host circuit's oscillator configuration. Ensure the operating temperature range meets the application environment constraints. Verify that the package dimensions align with available PCB footprint space and that the ESR values are compatible with the driving circuitry capabilities.

Crystals Part Context

The 445 Series represents CTS-Frequency Controls' line of glass-seal surface mount crystals. This family provides reliable frequency control solutions for compact electronic designs. The series utilizes AT-cut quartz resonators encapsulated in glass to ensure long-term stability and resistance to environmental stressors common in industrial and consumer applications.

Crystals Replacement Considerations

Direct substitutes include other 445 series variants with matching pinout and similar electrical specs, such as 445C23C30M00000 or 445C33D30M00000. Cross-brand replacements require careful verification of package dimensions, load capacitance, and ESR to ensure circuit compatibility without modification.
