LFXTAL078519B

Overview

The LFXTAL078519B is a through-hole quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 11.0592 MHz with a load capacitance of 20 pF. The component features a frequency tolerance and stability of ±30 ppm. It utilizes the HC-49/US package, measuring 11.35 mm in length and 4.85 mm in width. The equivalent series resistance (ESR) is specified as 40 Ohms. This device is designed for standard surface mount or through-hole integration within electronic circuits requiring precise timing references.

Feature Summary

• Provides stable oscillation at 11.0592 MHz using fundamental quartz resonance
• Compatible with standard HC-49/US mounting configurations for legacy designs
• Delivers consistent frequency performance across operational temperature ranges

Applications

• Microcontroller clock generation
• Serial communication interface timing
• General-purpose digital circuit synchronization

Procurement Notes

Verify the specific package variant against design requirements, as HC-49/US dimensions are standardized but lead spacing may vary. Confirm that the 20 pF load capacitance matches the oscillator circuit design to ensure accurate frequency operation. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the 40 Ohm ESR is within the acceptable range for the target application's driving circuit.

Selection Notes

Select this component when a standard 11.0592 MHz reference is required for baud rate generation in serial communications. The HC-49/US form factor supports automated insertion or manual placement in high-volume manufacturing. Consider the ±30 ppm tolerance sufficient for most non-critical timing applications. Evaluate the physical size constraints of the PCB layout to accommodate the 11.35 mm x 4.85 mm footprint.
