LFXTAL082081

Overview

The LFXTAL082081 is a surface-mount quartz crystal from the CFPX-218 series by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a frequency tolerance and stability of ±10 ppm. The component utilizes an 8 pF load capacitance and features a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a maximum height of 0.80 mm. Designed for base mode operation, it supports a temperature range of -40°C to +85°C and employs SMD/SMT termination.

Feature Summary

• Provides high frequency stability of ±10 ppm for precise timing applications
• Compact 4-SMD no-lead footprint suitable for space-constrained designs
• Operates reliably across an extended industrial temperature range

Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix (e.g., Reel, Bulk) when ordering, as packaging affects handling but not electrical performance. Confirm RoHS compliance status through official documentation prior to integration. Ensure the design accounts for the specified 8 pF load capacitance to maintain accuracy. Check current availability as supply levels may fluctuate.

Selection Notes

Select this component when a 20 MHz reference with tight ±10 ppm stability is required. The 4-SMD package offers a balance between size and manufacturability. Consider the -40°C to +85°C range against environmental conditions. Compare ESR and drive level requirements with circuit specifications to ensure optimal oscillation startup and longevity.

Part Context

This part belongs to the CFPX-218 series of surface-mount crystals. It complements other IQD frequency control products like standard oscillators and TCXOs. The series targets general-purpose electronics requiring reliable quartz-based timing solutions in compact form factors.

Replacement Considerations

Direct substitutes must match the 20 MHz frequency, ±10 ppm tolerance, 8 pF load capacitance, and 3.2x2.5mm package dimensions. Verify equivalent ESR and drive level specifications to prevent circuit malfunction.
