CSM1Z-A5B2C5-150-4.9152D18

Crystals Overview

The CSM1Z-A5B2C5-150-4.9152D18 is a surface-mount MHz crystal manufactured by Cardinal Components Inc. It operates at a nominal frequency of 4.9152 MHz with an 18 pF load capacitance. The component features a maximum equivalent series resistance (ESR) of 150 Ohms and maintains a frequency stability of ±50 ppm. Designed for base mode operation, it utilizes the HC-49/US package format with dimensions of 11.60 mm in length and 4.70 mm in width. The unit supports a standard operating temperature range from -20°C to +70°C.

Crystals Feature Summary

• Surface-mount design compatible with automated assembly processes
• HC-49/US package form factor for standardized footprint integration
• Base mode oscillation for fundamental frequency generation

Crystals Applications

• Digital clock signal generation in embedded systems
• Microcontroller oscillator circuits
• Communication module timing references

Crystals Procurement Notes

Verify that the replacement component matches the specific 150 Ohm ESR requirement, as this differs from standard lower-resistance variants. Confirm the 18 pF load capacitance aligns with the host circuit's oscillator design specifications. Ensure the HC-49/US SMD package dimensions fit the designated PCB layout without mechanical interference. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a higher ESR limit of 150 Ohms is required for specific oscillator circuit stability or drive level constraints. The 4.9152 MHz frequency is suitable for baud rate generation in serial communication interfaces requiring precise timing division. Consider the -20°C to +70°C operating range against the environmental conditions of the target application. Verify that the surface-mount configuration meets the manufacturing capabilities of the production line.

Crystals Part Context

This part belongs to the CSM1 series of MHz crystals from Cardinal Components Inc. The series offers various frequency options and ESR ratings tailored for different oscillator requirements.
