CSM4Z-A2B3C3-40-10.0D18

Crystals Overview

The CSM4Z-A2B3C3-40-10.0D18 is a parallel fundamental quartz crystal manufactured by Cardinal Components Inc. It operates at a nominal frequency of 10 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms. The component features a frequency stability and tolerance of ±30 ppm. Designed for surface mount installation, it utilizes the HC-49/US package format with dimensions of 11.60 mm in length, 4.70 mm in width, and a maximum height of 3.50 mm. The device supports a wide operating temperature range from -40°C to +85°C and is supplied in tape and reel packaging.

Crystals Feature Summary

• Surface mount design utilizing the standard HC-49/US package profile
• Fundamental oscillation mode operation for stable frequency generation
• Wide industrial temperature rating supporting extreme environmental conditions

Crystals Applications

• Microcontroller clock circuits
• Communication equipment timing references
• Industrial control system oscillators

Crystals Procurement Notes

Verify the specific suffix D18 corresponds to the required tape and reel configuration for automated assembly processes. Confirm that the 18 pF load capacitance matches the oscillator circuit design requirements to ensure accurate frequency performance. Ensure the HC-49/US footprint aligns with the target PCB layout constraints.

Crystals Selection Notes

Select this component when a fundamental mode crystal with ±30 ppm stability is required for 10 MHz applications. The 40 Ohm ESR value must be compatible with the driving circuit's capability to prevent overdriving. Consider the wider -40°C to +85°C temperature range if the application environment exceeds standard commercial limits.

Crystals Part Context

This part belongs to the CSM4 series of low-profile surface mount crystals from Cardinal Components Inc. The series offers various frequency and stability options within the HC-49/US form factor. The Z suffix indicates tape and reel packaging, distinguishing it from bulk pack variants within the same electrical specification family.

Crystals Replacement Considerations

Direct substitutes include other manufacturers offering HC-49S/SMD packages with 10 MHz frequency, 18 pF load capacitance, and ±30 ppm stability. Verify pin compatibility and physical dimensions before substitution.
