CY1.8432

Overview

The Jameco Electronics CY1.8432 is a passive crystal component designed for frequency control applications. It operates at a fundamental frequency of 1.8432 MHz and utilizes the HC49/U or HC18/U case style, which are standard through-hole packages suitable for general-purpose circuit integration. The device functions as a series resonant element with a specified impedance tolerance, providing stable oscillation for digital logic circuits, microcontrollers, and timing systems. This specific part number represents the Jameco Valuepro private label offering, ensuring compatibility with standard PCB layouts requiring these common crystal form factors.

Feature Summary

• Provides precise 1.8432 MHz frequency reference for oscillator circuits
• Utilizes standard HC49/U or HC18/U through-hole package for easy mounting
• Designed for series resonance operation in digital timing applications

Applications

• Microcontroller clock generation
• Digital timer circuits
• Frequency synthesis systems

Procurement Notes

Verify the specific case style requirement (HC49/U vs HC18/U) against your PCB footprint before ordering, as both are associated with this part number. Confirm that the series resonant type matches your oscillator circuit design. Ensure the impedance specifications align with your load capacitance requirements to guarantee accurate frequency stability in the final application.

Selection Notes

Select this component when a standard 1.8432 MHz frequency is required for basic timing or communication protocols. Consider the physical dimensions of the HC49/U or HC18/U package to ensure it fits within the designated area on the printed circuit board. Evaluate the operating temperature range and load capacitance requirements of the target system to ensure reliable performance under all expected conditions.

Part Context

This part belongs to Jameco's Valuepro line of passive components, specifically focusing on frequency control elements. It serves as a cost-effective alternative to branded crystals for non-critical timing applications. The CY1.8432 designation identifies the specific frequency and brand assignment within Jameco's extensive inventory of discrete semiconductor and passive parts used in electronics manufacturing.

Replacement Considerations

Cross-reference tools may identify parametrically similar parts from other manufacturers. Verify that any substitute maintains the same 1.8432 MHz frequency, series resonance mode, and compatible case style to ensure mechanical and electrical interchangeability without redesigning the host circuit.
