Feature Summary

• Fundamental oscillation mode operation
• Through-hole termination style for reliable mechanical attachment
• Standard commercial-grade frequency stability specifications

Applications

• Microcontroller clock circuits
• Serial communication interface timing
• General-purpose digital logic synchronization

Procurement Notes

Verify the specific package variant against the datasheet, as HC-49/U and HC-49/S dimensions differ. Confirm that the 20pF load capacitance matches the oscillator circuit design requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Cross-reference the ESR value with the driving level constraints of the host system.

Selection Notes

Select this component when a precise 11.0592 MHz frequency is required for baud rate generation in serial communications. The fundamental mode offers stable performance for general digital applications. Consider the through-hole form factor if PCB layout constraints favor manual assembly or higher mechanical robustness over surface mount density.
