LFXTAL003099BULK

Overview

The LFXTAL003099BULK is a through-hole quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 4.433619 MHz, typically used for color subcarrier applications in video systems. The component features a frequency stability of ±50 ppm and a load capacitance of 20 pF or 30 pF depending on specific variant documentation. It is housed in a standard leaded package suitable for wave or manual soldering. The device complies with RoHS standards and is designed for reliable performance in consumer electronics and broadcast equipment requiring precise timing references.

Feature Summary

• Provides stable oscillation at the NTSC color subcarrier frequency
• Through-hole mounting for robust mechanical connection
• Compliant with environmental safety standards

Applications

• NTSC video signal processing circuits
• Color television receivers
• Video recording equipment
• Broadcast transmission hardware

Procurement Notes

Verify the exact load capacitance specification (20 pF vs 30 pF) against the specific datasheet revision prior to ordering, as legacy part numbers may have variant differences. Confirm that the through-hole package style matches the target PCB footprint requirements. Ensure compatibility with the oscillator circuit's drive level specifications to prevent over-driving the crystal. Check for any specific handling instructions regarding moisture sensitivity if stored for extended periods.

Selection Notes

Select this component when a precise 4.433619 MHz reference is required for analog video color decoding. The through-hole format is preferred for high-reliability industrial or legacy board designs where surface mount is not feasible. Consider the ±50 ppm stability tolerance which is adequate for consumer-grade video applications but may require tighter tolerances for professional broadcast gear. Evaluate the physical size constraints of the through-hole hole pattern during layout design.

Part Context

This part belongs to IQD Frequency Products' extensive line of quartz crystal resonators. IQD is a recognized supplier of frequency control components, now part of the Wurth Group. The LFXTAL series covers various frequencies and packages, serving diverse markets from automotive to consumer electronics. This specific model addresses the niche requirement for the standard NTSC color burst frequency, a critical timing element in older video technologies.

Replacement Considerations

Direct replacements must match the 4.433619 MHz frequency and through-hole package dimensions. Other manufacturers producing NTSC crystals may offer equivalents, but verify load capacitance and frequency tolerance alignment. Ensure the replacement part maintains the same fundamental mode of vibration and electrical characteristics to guarantee proper circuit operation without retuning.
