XXHEELAANF-18.432000

Crystals Overview

The Taitien XXHEELAANF-18.432000 is a surface-mount crystal resonator operating at a fundamental frequency of 18.432 MHz. It features a frequency stability and tolerance of ±30 ppm across its operational range. The component utilizes a load capacitance of 20 pF and exhibits an equivalent series resistance (ESR) of 80 Ohms. It is housed in a compact 4-SMD, No Lead package, designed for integration into precision timing circuits requiring stable quartz-based oscillation.

Crystals Feature Summary

• Provides precise 18.432 MHz timing reference
• Compact surface-mount footprint for automated assembly
• Stable quartz resonance with defined load capacitance

Crystals Applications

• Precision clock generation in digital logic systems
• Microcontroller and processor base clocks
• Communication interface synchronization

Crystals Procurement Notes

Verify the specific revision level and lot traceability requirements against your manufacturing standards before ordering. Confirm that the 4-SMD no-lead package dimensions align with your PCB land pattern design. Ensure storage conditions comply with moisture sensitivity levels to maintain solderability upon reflow. Cross-reference the ±30 ppm stability requirement with your system's total allowable jitter budget.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required rather than an integrated oscillator IC. The 20 pF load capacitance must match the external circuit design to achieve the specified ±30 ppm accuracy. Consider the 80 Ohm ESR limit for drive level constraints within the host circuit. This part is suitable for applications where size constraints preclude larger through-hole packages but do not require active output buffering.

Crystals Part Context

This model belongs to Taitien's portfolio of passive quartz crystal resonators. Unlike active oscillators such as the PXETDLJANF or OCETGLJANF series which provide powered outputs, this component requires an external oscillator circuit to function. It serves as the frequency-determining element in standard microcontroller or FPGA clock architectures.

Crystals Replacement Considerations

Direct substitutes must match the 18.432 MHz frequency, 20 pF load capacitance, 80 Ohm ESR, and 4-SMD no-lead package. Verify that alternative manufacturers offer identical ±30 ppm stability and compatible mounting pad geometries to ensure mechanical and electrical interchangeability without redesign.
