LFXTAL081619

Overview

The LFXTAL081619 is a surface-mount quartz crystal resonator manufactured by IQD Frequency Products. It operates at a fundamental frequency of 40 MHz with a specified frequency tolerance of ±10 ppm and a frequency stability of ±20 ppm. The component features an equivalent series resistance (ESR) of 100 Ohms and requires a load capacitance of 8 pF. Designed for robust performance, it supports a wide operating temperature range from -40°C to +105°C. The device utilizes a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.80mm, making it suitable for space-constrained electronic designs.

Feature Summary

• High precision frequency control with ±10 ppm initial tolerance
• Wide industrial temperature operation capability up to 105°C
• Compact surface-mount footprint for automated assembly

Applications

• Precision timing circuits in embedded systems
• Clock generation for microcontrollers and processors
• Communication interface synchronization modules

Procurement Notes

Verify the specific load capacitance requirements of your oscillator circuit against the 8pF specification to ensure accurate frequency tuning. Confirm that the 100 Ohm ESR aligns with your circuit's drive level limitations to prevent over-driving the crystal. Ensure the selected packaging variant matches your pick-and-place equipment capabilities for the 4-SMD form factor.

Selection Notes

Select this component when high frequency accuracy is critical for system synchronization. The ±10 ppm tolerance offers superior stability compared to standard commercial-grade crystals. Consider the 40 MHz frequency point for applications requiring precise baud rates or clock division ratios. Evaluate the thermal stability requirements to confirm the -40°C to +105°C range meets environmental conditions.

Part Context

This part belongs to the general quartz crystal portfolio of IQD Frequency Products, a subsidiary of Wurth Elektronik specializing in frequency control solutions. IQD provides extensive ranges of SMD and through-hole crystals for diverse industries including automotive, industrial, and consumer electronics. The LFXTAL series represents their standard line of fundamental mode quartz resonators designed for reliable long-term performance.

Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 8pF load capacitance, and 4-SMD 3.2x2.5mm package. Verify compatibility regarding ESR values and temperature stability specifications before integration.
