LFXTAL059611

Overview

The LFXTAL059611 is a quartz crystal resonator manufactured by IQD Frequency Products, operating at a fundamental frequency of 13.56 MHz. It features a frequency tolerance of ±20 ppm and a stability of ±50 ppm. The component has a load capacitance of 18 pF and an equivalent series resistance (ESR) of 120 Ohms. It utilizes the CFPX-180 series package in a 4-SMD, No Lead configuration with dimensions of 3.20mm x 2.50mm x 0.80mm maximum height. Designed for surface mount installation, it supports base harmonic operation mode.

Feature Summary

• Provides precise timing reference at 13.56 MHz with tight frequency tolerance
• Compact 4-SMD no-lead footprint suitable for space-constrained designs
• Operates reliably across industrial temperature ranges

Applications

• RFID reader and writer systems
• Wireless communication modules
• Industrial control equipment

Procurement Notes

Verify the specific ordering suffix and packaging type (Tape & Reel, Cut Tape, or Digi-Reel) required for your production line before placing orders. Confirm that the manufacturer part number matches exactly to avoid substitution errors. Check current availability status as supply levels may fluctuate. Ensure compliance with RoHS directives if applicable to your region. Request official datasheets for final design integration validation.

Selection Notes

Select this component when a stable 13.56 MHz reference is needed for SMD assembly. The 18 pF load capacitance must match the oscillator circuit requirements. Consider the 120 Ohm ESR value for drive level sensitivity. The small 3.20mm x 2.50mm size aids in high-density PCB layouts. Verify temperature range compatibility with the operational environment.

Part Context

This crystal belongs to the CFPX-180 series from IQD Frequency Products, which specializes in miniature surface mount crystals. The series offers various frequencies and packages optimized for modern electronics manufacturing. IQD provides these components for applications requiring reliable frequency control in compact form factors.

Replacement Considerations

Direct substitutes must match the 13.56 MHz frequency, 18 pF load capacitance, 4-SMD no-lead package, and similar electrical parameters. Cross-reference with other manufacturers offering compatible SMD crystals in the same footprint.
