445W23D12M00000

Crystals Overview

The CTS-Frequency Controls 445W23D12M00000 is a surface-mount quartz crystal resonator operating at a fundamental frequency of 12 MHz. It features a load capacitance of 18 pF and offers a frequency tolerance of ±20 ppm with a stability of ±15 ppm. The component utilizes glass seal technology within a 5 mm x 3.2 mm SMD package, measuring 1.35 mm in height. It operates within a temperature range of -40°C to +85°C and has an equivalent series resistance (ESR) of 50 Ohms.

Crystals Feature Summary

• Utilizes glass seal construction for enhanced environmental durability and long-term reliability.
• Operates at the fundamental mode to ensure precise frequency generation.
• Designed for surface-mount assembly to facilitate automated PCB placement.

Crystals Applications

• General-purpose clock signal generation in electronic circuits
• Microcontroller and microprocessor system timing references
• Communication interface synchronization

Crystals Procurement Notes

Verify that the specific suffix 'W' aligns with the required frequency tolerance and stability specifications for the target application. Confirm that the 18 pF load capacitance matches the oscillator circuit design requirements. Ensure the glass seal construction meets the environmental protection standards necessary for the operating conditions.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency with ±20 ppm tolerance is required. The 18 pF load capacitance must match the host circuit's capacitive load. The glass seal technology provides superior stability compared to standard epoxy-sealed crystals, making it suitable for applications demanding higher precision over the specified temperature range.

Crystals Part Context

This part belongs to the CTS 445 Series, which specializes in glass seal quartz crystals. The series is characterized by high Q-factor and excellent frequency stability. The 445W variant specifically denotes the tolerance and stability parameters associated with the glass seal construction method used by CTS-Frequency Controls.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz glass seal crystals with identical 18 pF load capacitance and ±20 ppm tolerance. Verify that replacement parts maintain the same 5x3.2mm footprint and ESR characteristics to ensure circuit compatibility without redesign.
