CSM1Z-A0B2C3-100-6.0D18

Crystals Overview

The CSM1Z-A0B2C3-100-6.0D18 is a parallel fundamental quartz crystal manufactured by Cardinal Components Inc. It operates at a nominal frequency of 6.0 MHz with a load capacitance of 18 pF. The component features an equivalent series resistance (ESR) of 100 Ohms and supports surface mount installation in an HC-49/US package measuring 11.60mm x 4.70mm x 4.60mm. It complies with RoHS standards, operates within a temperature range of -10°C to +60°C, and offers a frequency tolerance of ±30 ppm alongside a stability of ±50 ppm.

Crystals Feature Summary

• Surface mount ceramic construction for reliable PCB integration
• Fundamental parallel resonance mode operation
• RoHS compliant lead-free manufacturing process

Crystals Applications

• Microcontroller clock signal generation
• Embedded system timing references
• General-purpose digital circuit oscillators

Crystals Procurement Notes

Verify the specific ESR value of 100 Ohms against circuit requirements, as this differs from standard lower-resistance variants. Confirm the HC-49/US footprint compatibility during layout. Ensure the operating temperature range of -10°C to +60°C meets environmental specifications. Cross-reference the 18 pF load capacitance with oscillator design parameters to guarantee frequency accuracy.

Crystals Selection Notes

Select this component when a higher ESR of 100 Ohms is required for specific oscillator stability or drive level constraints. The HC-49/US surface mount form factor provides a balance between mechanical robustness and space efficiency compared to smaller packages. Consider the ±30 ppm tolerance for applications requiring moderate frequency precision without demanding ultra-tight tolerances.

Crystals Part Context

This part belongs to the CSM1 series of ceramic surface mount crystals from Cardinal Components Inc. The series utilizes AT-cut quartz resonators housed in ceramic packages. The suffix codes define specific electrical and physical attributes, including the 100 Ohm ESR and 6.0 MHz frequency, distinguishing it from other variants in the lineup.

Crystals Replacement Considerations

Direct substitutes must match the 100 Ohm ESR, 18 pF load capacitance, and HC-49/US SMD footprint. Verify that alternative manufacturers offer components with identical ±30 ppm tolerance and -10°C to +60°C operating ranges to ensure functional equivalence.
