CSM1Z-A0B2C3-100-7.3728D18

Crystals Overview

The CSM1Z-A0B2C3-100-7.3728D18 is a fundamental quartz crystal manufactured by Cardinal Components Inc. It operates at a nominal frequency of 7.3728 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component features an equivalent series resistance (ESR) of 100 Ohms and a load capacitance of 18 pF. It utilizes an AT-cut resonator housed in a surface-mount HC-49/US package, measuring 11.60 mm in length, 4.70 mm in width, and 4.60 mm in height. The device supports a driving level of 1 mW and maintains an aging rate of 5 ppm per year. Operating temperatures range from -20°C to +70°C.

Crystals Feature Summary

• AT-cut fundamental resonance design for stable oscillation
• Low profile surface-mount construction compatible with automated assembly
• RoHS compliant lead-free manufacturing process

Crystals Applications

• Microcontroller clock sources
• Embedded system timing references
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix D18 corresponds to the required load capacitance and packaging configuration. Confirm that the 100 Ohm ESR aligns with the oscillator circuit design requirements. Ensure the operating temperature range of -20°C to +70°C meets the environmental specifications of the target application. Cross-reference the RoHS compliance status if restricted substance regulations apply.

Crystals Selection Notes

Select this component when a 7.3728 MHz reference is required for digital logic or communication protocols. The 18 pF load capacitance must match the external capacitors in the oscillator circuit to ensure accurate frequency generation. The 100 Ohm ESR value dictates the necessary drive strength; verify that the host circuit does not exceed the 1 mW maximum driving level to prevent frequency drift or damage.

Crystals Part Context

This part belongs to the CSM1 series of low-profile surface-mount crystals from Cardinal Components Inc.
