LFXTAL014948B

Overview

The LFXTAL014948B is a through-hole quartz crystal resonator manufactured by IQD Frequency Products. It operates at a fundamental frequency of 27.12 MHz with a tolerance of ±30 ppm and a load capacitance of 30 pF. The component utilizes an HC-49/US package, measuring 11.05 mm in length, 4.65 mm in width, and 13.46 mm in height. It supports a radial termination style and functions within a temperature range of -10°C to +60°C. Key electrical specifications include a maximum equivalent series resistance (ESR) of 100 Ohms and a drive level of 1 mW.

Feature Summary

• Provides stable timing signals for digital circuits using a fundamental mode quartz resonator.
• Features a robust HC-49/US through-hole package designed for reliable PCB mounting.
• Maintains frequency stability within specified limits across the designated operating temperature range.

Applications

• Microcontroller clock generation
• Digital communication interfaces
• General-purpose timing circuits

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as bulk quantities may differ from tape-and-reel options. Confirm that the HC-49/US footprint matches the target PCB design constraints. Ensure the operating temperature range of -10°C to +60°C aligns with the environmental requirements of the final assembly. Cross-reference the datasheet for any recent updates regarding RoHS compliance or material declarations before finalizing procurement.

Selection Notes

Select this component when a standard through-hole crystal is required for 27.12 MHz applications. The HC-49/US form factor offers mechanical stability suitable for general industrial and commercial environments. Consider the 100 Ohm ESR limit to ensure compatibility with the oscillator circuit's impedance matching requirements. Verify that the ±30 ppm tolerance meets the system's jitter and synchronization specifications.

Part Context

This part belongs to the IQD LFXTAL series of standard quartz crystals. It is distinct from surface-mount variants and higher-stability TCXO models. The HC-49/US package is a legacy but widely adopted standard for through-hole mounting. It serves as a cost-effective solution for basic timing needs where extreme precision or miniaturization is not critical.

Replacement Considerations

Direct substitutes must match the 27.12 MHz frequency, HC-49/US package, and 30 pF load capacitance. Check alternative manufacturers for identical pin-out dimensions and electrical parameters. Verify that replacement parts meet the same -10°C to +60°C temperature rating and 1 mW drive level specifications.
