LFXTAL078427BULK

Overview

The LFXTAL078427BULK is a quartz crystal manufactured by IQD Frequency Products, designed for general timing applications. It operates at a nominal frequency of 8.0000 MHz with a load capacitance of 18 pF. The component utilizes an HC49/3.5H package, featuring radial termination suitable for through-hole mounting. Electrical specifications include a frequency tolerance and stability of ±50 ppm at 25°C. The device supports a drive level of 100 µW and maintains an equivalent series resistance (ESR) of 50 Ohms. It functions within an operating temperature range of -10°C to +60°C. Physical dimensions are 11.05 mm in length, 4.7 mm in width, and 4.3 mm in height.

Feature Summary

• Hermetically sealed construction using industry-standard leaded packaging with glass-to-metal seals on leads.
• Resistance welded design ensuring reliability in inert atmosphere environments.
• Radial termination style facilitates standard through-hole PCB integration.

Applications

• General-purpose digital circuit timing
• Microcontroller clock sources
• Consumer electronics timing references

Procurement Notes

Verify the specific suffix 'Bulk' against the manufacturer's current datasheet to confirm packaging configuration. Ensure the HC49/3.5H package variant matches the target PCB footprint requirements. Cross-reference the RoHS compliance status directly with the official product documentation prior to procurement to meet regulatory standards.

Selection Notes

Select this component when a standard 8 MHz through-hole crystal is required for non-critical timing applications. The HC49/3.5H package offers a balance of size and mechanical robustness. Consider the ±50 ppm stability limit for oscillator circuit design. Verify that the 18 pF load capacitance aligns with the host system's oscillator circuit parameters.

Part Context

This part belongs to the IQD Frequency Products quartz crystal lineup, which provides various frequency control solutions. The LFXTAL series typically includes both surface mount and through-hole options. This specific model represents a traditional leaded crystal solution, distinct from the company's SMD or temperature-compensated oscillator offerings.

Replacement Considerations

Direct substitutes must match the 8 MHz frequency, 18 pF load capacitance, HC49/3.5H package, and ±50 ppm stability. Verify pin compatibility and electrical characteristics before substitution.
