LFXTAL003063BULK

Overview

The IQD Frequency Products LFXTAL003063BULK is a quartz crystal oscillator operating at a nominal frequency of 3.579545 MHz. It features a load capacitance of 20 pF and a frequency tolerance of ±30 ppm at 25°C. The unit maintains a frequency stability of ±50 ppm across the operating temperature range of -20°C to +70°C. Key electrical specifications include an equivalent series resistance (ESR) of 300 Ohms maximum and a drive level of 500 µW. The component utilizes an HC-49/4H radial through-hole package with dimensions of 11.05 mm in length, 4.7 mm in width, and 4.1 mm in height.

Feature Summary

• Industry-standard leaded package construction with resistance welding and inert gas filling for hermetic sealing.
• Glass-metal sealed leads ensuring long-term reliability and protection against environmental degradation.
• Base mode oscillation capability eliminating the need for overtone matching circuits.

Applications

• NTSC color subcarrier generation in video processing systems
• Motor control applications requiring stable clock signals
• Industrial equipment operating within specified thermal ranges

Procurement Notes

Verify the specific ordering suffix and packaging configuration when placing orders, as availability may vary between bulk reels and cut tape formats. Confirm that the required load capacitance matches the target circuit design to ensure accurate frequency performance. Check current RoHS compliance status and any recent part number revisions from the manufacturer before finalizing procurement documentation.

Selection Notes

Select this component when a precise 3.579545 MHz reference is required for NTSC-compatible video applications. Ensure the system's oscillator circuit can support the specified 500 µW drive level and 300 Ohm ESR without instability. Verify that the operating environment remains within the -20°C to +70°C range to maintain the guaranteed ±50 ppm stability specification.

Part Context

This crystal belongs to the HC49/4H series from IQD Frequency Products, designed for general-purpose timing applications. The series is characterized by robust mechanical construction suitable for through-hole mounting on printed circuit boards. It serves as a fundamental frequency reference for microcontrollers and logic circuits requiring high stability.

Replacement Considerations

Direct substitutes must match the 3.579545 MHz frequency, 20 pF load capacitance, and HC-49/4H package dimensions. Verify that alternative sources offer comparable ±30 ppm tolerance and similar ESR characteristics to prevent frequency drift or oscillation failure in existing designs.
