• Consumer electronics control systems

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current part numbering guide to ensure correct tolerance and temperature range specifications. Confirm that the HC-49S footprint matches the target PCB layout. Check for RoHS compliance documentation if required by regulatory standards. Ensure the selected variant matches the required load capacitance for the oscillator circuit.

Crystals Selection Notes

Select this component when a standard 16 MHz frequency is required for general-purpose digital logic or microcontrollers. The HC-49S form factor provides a balance between size and performance for through-hole or surface-mount applications. Consider the ±30 ppm tolerance for basic timing requirements where high precision is not critical. Verify compatibility with the driving circuit's power limits.

Crystals Part Context

This part belongs to the CSM1 series of low-profile surface mount crystals from Cardinal Components. The series offers cost-effective solutions for fundamental mode applications. The CSM1 line utilizes epoxy-sealed ceramic packages to provide durability while maintaining competitive pricing for high-volume production environments.
