LFXTAL003515BULK

Overview

The LFXTAL003515BULK is a parallel fundamental 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 of 20 ppm and a frequency stability of 50 ppm. It utilizes an HC-49 package style with radial termination for through-hole mounting. The unit supports a drive level of 1 mW and has an equivalent series resistance (ESR) of 35 Ohms. The operating temperature range extends from -10°C to +60°C.

Feature Summary

• Hermetically sealed in an inert atmosphere using glass-to-metal seals on leads
• Industry standard leaded HC-49 package construction
• Resistance welded connections for reliable electrical contact

Applications

• Microcontroller clock circuits
• Serial communication interfaces
• Digital logic timing references

Procurement Notes

Verify the specific packaging suffix against official IQD documentation, as bulk availability may vary by region. Confirm that the required frequency tolerance and stability meet the target circuit specifications before finalizing the order. Ensure the through-hole mounting style aligns with the printed circuit board design constraints.

Selection Notes

Select this component when a standard 11.0592 MHz reference is required for asynchronous serial data transmission due to its baud rate divisibility. The HC-49 form factor provides mechanical robustness for general-purpose electronics. Consider the 35 Ohm ESR value to ensure compatibility with the oscillator circuit's loading requirements.

Part Context

This part belongs to the IQD LFXTAL series of parallel fundamental quartz crystals. These components are designed for general-purpose timing applications requiring stable frequency generation. The HC-49 package is widely used in industrial and consumer electronics for its standardized dimensions and reliable performance characteristics.

Replacement Considerations

Direct substitutes include other manufacturers' HC-49 crystals with identical 11.0592 MHz frequency, 20 pF load capacitance, and similar ESR values. Verify that alternative parts meet the same frequency tolerance and stability requirements for the specific application environment.
