LFXTAL003033BULK

Overview

The LFXTAL003033BULK is a through-hole quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 1.8432 MHz with a tolerance of ±20 ppm and stability of ±50 ppm. The component features a load capacitance of 30 pF and an equivalent series resistance (ESR) of 800 Ohms. It supports a drive level of 1 mW and functions within a temperature range of -10°C to +60°C. The physical package is HC-49, measuring 11.05 mm in length, 4.65 mm in width, and 13.46 mm in height, with a lead spacing of 4.88 mm.

Feature Summary

• Provides stable oscillation for high-frequency applications using quartz technology
• Designed for through-hole mounting with radial termination style
• Operates within standard industrial temperature ranges

Applications

• Clock generation circuits
• Microcontroller timing references
• Communication interface synchronization

Procurement Notes

Verify the specific suffix BULK indicates bulk packaging rather than tape and reel when ordering. Confirm that the HC-49 package dimensions align with the target PCB footprint. Ensure the circuit design accommodates the specified 800 Ohm ESR and 1 mW drive level to prevent overdriving the crystal. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 1.8432 MHz reference is required for through-hole designs. The HC-49 form factor suits manual assembly or wave soldering processes. Consider the ±50 ppm stability requirement against system timing constraints. The 30 pF load capacitance must match the oscillator circuit's external capacitor values for accurate frequency tuning.

Part Context

This part belongs to the IQD LFXTAL series of general-purpose quartz crystals. It utilizes the standard HC-49 can package, widely used in legacy and modern electronics for its robust mechanical structure. The product line covers various frequencies and packages, serving diverse consumer and industrial electronic needs.

Replacement Considerations

Direct substitutes include other HC-49 crystals with identical 1.8432 MHz frequency, 30 pF load capacitance, and similar ESR characteristics. Verify that alternative manufacturers meet the same ±20 ppm tolerance and ±50 ppm stability specifications.
