445W25F12M00000

Crystals Overview

The CTS-Frequency Controls 445W25F12M00000 is a surface-mount quartz crystal resonator operating at a fundamental frequency of 12 MHz. It features a frequency tolerance of ±20 ppm and a load capacitance of 24 pF. The component exhibits an equivalent series resistance (ESR) of 50 Ohms and operates within a temperature range of 0°C to +50°C. Designed for SMD/SMT installation, it utilizes a leadless two-terminal package with dimensions of 2 mm by 1.6 mm.

Crystals Feature Summary

• Fundamental mode operation for stable frequency generation
• Leadless surface-mount design for compact circuit integration
• Gold-plated terminals with nickel barrier for corrosion resistance

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Crystals Procurement Notes

Verify the specific terminal finish configuration, as some variants in this series utilize gold plating with a nickel barrier. Confirm that the 24 pF load capacitance aligns precisely with the host oscillator circuit requirements to ensure accurate frequency performance. Ensure the selected part number matches the required leadless package style.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency with ±20 ppm tolerance is required in a compact leadless footprint. The 24 pF load capacitance specification must match the system's capacitive load. Consider the 50 Ohm ESR limit for oscillator drive level compatibility. This model suits applications requiring robust surface-mount assembly with standard industrial temperature ranges.

Crystals Part Context

This part belongs to the CTS 445 series of surface-mount crystals. The series offers various frequencies and package styles optimized for consumer electronics and industrial control systems. The 445W25F variant specifically denotes a leadless form factor designed for high-volume automated placement processes.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz leadless crystals from CTS with matching 24 pF load capacitance and ±20 ppm tolerance, such as the 445W25J12M00000 if terminal finish specifications are compatible.
