Overview
The LFXTAL078424BULK is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 16 MHz with a load capacitance of 20 pF. The component exhibits a frequency tolerance of ±30 ppm and a stability of ±50 ppm over the operating temperature range of -10°C to +70°C. It features an equivalent series resistance (ESR) of 40 Ohms and utilizes a two-pin HC-49 through-hole package.
Feature Summary
- Fundamental mode quartz crystal construction
- HC-49 through-hole mounting configuration
- Extended temperature operation capability
Applications
- General-purpose timing circuits
- Microcontroller clock sources
- Industrial control systems
Procurement Notes
Verify the specific suffix 'BULK' indicates loose packaging rather than tape and reel when sourcing. Confirm that the HC-49 form factor matches the target PCB footprint requirements. Ensure the -10 to +70°C commercial temperature grade aligns with the environmental specifications of the end application before finalizing procurement.
Selection Notes
Select this component for applications requiring standard through-hole assembly and moderate frequency stability. The 20 pF load capacitance requires matching oscillator circuit design. Consider the 40 Ohm ESR value for drive level limitations. This part serves as a cost-effective solution for non-critical timing needs where surface mount options are not mandatory.
Part Context
This part belongs to the IQD Frequency Products quartz crystal lineup, which includes various SMD and through-hole packages. The manufacturer provides components ranging from basic crystals to high-performance oscillators. The LFXTAL series specifically denotes fundamental mode crystals suitable for diverse electronic timing applications across commercial and industrial sectors.
Replacement Considerations
Cross-reference with other 16 MHz HC-49 crystals ensuring identical 20 pF load capacitance and ±30 ppm tolerance. Verify compatibility with existing oscillator circuit parameters.
