LFXTAL082070REEL

Overview

The LFXTAL082070REEL is a surface-mount quartz crystal oscillator from the CFPX-180 series, manufactured by IQD Frequency Products. It operates at a fundamental frequency of 13.56 MHz with an initial frequency tolerance of ±10 ppm and a total frequency stability of 20 ppm over temperature. The component requires an external load capacitance of 8 pF and features a low equivalent series resistance of 120 Ohms. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C. The device utilizes a compact 4-SMD, No Lead package measuring 3.2 mm in length, 2.5 mm in width, and 0.8 mm in height, suitable for automated SMD/SMT assembly processes.

Feature Summary

• Provides stable oscillation at the standard RFID frequency of 13.56 MHz
• Offers high frequency accuracy with ±10 ppm initial tolerance
• Supports wide industrial operating temperatures from -40°C to +85°C
• Utilizes a compact, leadless surface-mount package for space-constrained designs

Applications

• RFID reader and tag circuits
• Wireless communication modules
• Industrial control systems requiring precise timing
• Consumer electronics with NFC capabilities

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as the manufacturer has updated part number revisions. Confirm that the required reel quantity matches your production needs, as factory packaging quantities may vary. Ensure compatibility with your PCB footprint dimensions, specifically the 3.2mm x 2.5mm outline. Cross-reference the latest datasheet for any changes in mechanical tolerances or electrical specifications prior to finalizing the bill of materials.

Selection Notes

Select this component when a precise 13.56 MHz reference is required for short-range wireless applications. The 8 pF load capacitance requirement dictates the necessary circuit design adjustments for the host oscillator. Consider the 120 Ohm ESR value to ensure adequate drive level management within the system. The wide temperature range makes it suitable for environments where standard commercial grade crystals might fail. Verify that the clipped sine wave output format aligns with the input requirements of the connected microcontroller or RF transceiver.

Part Context

This part belongs to the CFPX-180 series of thin, low-profile quartz crystals. It serves as a direct replacement for previous iterations of the LFXTAL082070 designation, reflecting manufacturer part number updates. The series is characterized by its small form factor and reliability in mass-produced consumer and industrial electronics. It complements other IQD frequency control products designed for compact mobile and IoT devices.

Replacement Considerations

The document notes that the LFXTAL082070REEL is a revised part number replacing the previous LFXTAL082070 designation. Engineers should verify pinout and mechanical compatibility before swapping between these identifiers. No alternative substitute part numbers are publicly confirmed in the provided documentation.
