CY3.57

Overview

The Jameco Electronics CY3.57 is a ceramic resonator operating at a fundamental frequency of 3.579545 MHz. It is housed in an HC-49/U or HC-18/U package, providing a compact and reliable solution for timing applications. This component serves as a cost-effective alternative to quartz crystals in circuits requiring stable clock signals.

Feature Summary

• Provides stable oscillation at a specific frequency
• Available in standard through-hole packages

Applications

• Microcontroller clock sources
• Simple oscillator circuits
• Timing references in consumer electronics

Procurement Notes

Verify the exact package variant (HC-49/U vs. HC-18/U) required for your PCB footprint before ordering. Confirm that the ceramic resonator technology meets the phase noise and stability requirements of your design, as it differs from quartz crystal specifications. Ensure compatibility with the driving circuit impedance.

Selection Notes

Select this component when a low-cost timing solution is acceptable and high precision is not critical. Compare its load capacitance requirements against your oscillator circuit design. Consider environmental factors such as temperature stability, which may be less precise than quartz alternatives.

Part Context

This part belongs to the category of electronic components known as crystals or ceramic resonators. Jameco Electronics distributes this item as a general-purpose timing element. The model number directly indicates its nominal operating frequency, distinguishing it from other variants in their inventory.

FAQ

What is the difference between HC-49/U and HC-18/U packages?

Both are through-hole ceramic resonator packages. HC-49/U is larger and more common, while HC-18/U is smaller. Verify your board space constraints when choosing.

Is this a quartz crystal or a ceramic resonator?

It is a ceramic resonator. Ceramic resonators are generally less expensive but offer lower frequency stability and higher temperature drift compared to quartz crystals.
