CSM1Z-A5B2C5-70-10.0D18

Crystals Overview

The CSM1Z-A5B2C5-70-10.0D18 is a fundamental series quartz crystal manufactured by Cardinal Components Inc., designed for surface-mount applications. It operates at a nominal frequency of 10.0000 MHz with a load capacitance of 18 pF. The component features an equivalent series resistance (ESR) of 70 Ohms and a frequency tolerance of ±30 ppm, ensuring stable performance within its operating temperature range of -10°C to +60°C. Packaged in the HC-49/US form factor measuring 11.60mm x 4.70mm x 4.60mm, it supports tape-and-reel delivery for automated assembly processes.

Crystals Feature Summary

• Surface-mount construction utilizing the standard HC-49/US package profile for reliable PCB integration.
• Fundamental series resonance mode operation providing precise frequency control for timing circuits.
• Compliance with RoHS directives ensuring environmental safety standards are met.

Crystals Applications

• General-purpose timing references in consumer electronics
• Clock signal generation in computer peripheral devices
• Frequency control in industrial instrumentation

Crystals Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 70 Ohm ESR and 18 pF load capacitance, as these values are critical for oscillator circuit stability. Confirm the packaging format corresponds to tape-and-reel requirements for your assembly line equipment. Ensure the supplier provides documentation confirming RoHS compliance status prior to finalizing the purchase order.

Crystals Selection Notes

Select this component when a standard HC-49/US footprint is required but surface-mount technology is preferred over through-hole mounting. The 10 MHz frequency is suitable for microcontroller clock inputs or communication interfaces requiring this specific base rate. Consider the ±30 ppm tolerance if higher precision is not strictly necessary for the application environment.

Crystals Part Context

This component belongs to the CSM1 series of low-profile surface mount crystals from Cardinal Components Inc. The series is characterized by cost-effective manufacturing and fast delivery options while maintaining standard electrical specifications. The CSM1 series offers various frequency and tolerance combinations within the same physical package, allowing for design flexibility across different product lines.

Crystals Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the CSM1Z-A0B2C3-50-10.0D18, which shares the same frequency and package but differs in ESR and temperature rating. Cross-manufacturer equivalents such as those from Citizen Finedevice may require verification of mechanical dimensions and electrical characteristics against the original schematic requirements.
