XIHEELAANF-4.000000

Crystals Overview

The Taitien XIHEELAANF-4.000000 is a through-hole crystal operating at 4 MHz with ±30 ppm frequency stability and tolerance. It features a 20 pF load capacitance and 120 Ohms equivalent series resistance. The component utilizes an HC-49/US package, suitable for standard mounting applications.

Crystals Feature Summary

• Through-hole mounting configuration in HC-49/US package
• Fundamental mode operation at 4 MHz
• ±30 ppm frequency stability and tolerance

Crystals Applications

• General-purpose clock generation circuits
• Microcontroller system timing references
• Consumer electronics control boards

Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm exact electrical parameters and mechanical dimensions before integration. Ensure the HC-49/US footprint matches the target PCB design. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with official distributor catalogs to validate current availability and authenticity.

Crystals Selection Notes

Select this component when a fundamental mode crystal with 4 MHz frequency is required for through-hole assembly. The 20 pF load capacitance must match the oscillator circuit design. Consider the 120 Ohms ESR value for drive level compatibility. This package type is appropriate for manual or wave soldering processes rather than surface mount reflow.

Crystals Part Context

This part belongs to the Taitien crystal family, designed for stable frequency reference in electronic systems. The XIHEELAANF series typically offers reliable performance across standard industrial temperature ranges. It serves as a passive frequency-determining element in resonant circuits.

Crystals Replacement Considerations

Compatible substitutes include other HC-49/US crystals with 4 MHz frequency, 20 pF load capacitance, and similar ESR values. Verify that alternative parts maintain the same fundamental mode operation and package dimensions for direct pin-to-pin replacement.
