LFXTAL054208

Overview

The LFXTAL054208 is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 12 MHz with a frequency tolerance and stability of ±10 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 120 Ohms. It utilizes a 4-SMD, No Lead package measuring 3.2 mm in length, 2.5 mm in width, and 0.8 mm in height. The device supports a maximum drive level of 100 uW and functions within a temperature range of -20°C to +70°C.

Feature Summary

• Provides precise timing reference through fundamental mode quartz resonance
• Ensures stable frequency output with tight ±10 ppm tolerance
• Designed for compact surface-mount integration via leadless SMD footprint

Applications

• Microcontroller clock generation circuits
• Communication interface synchronization
• Digital signal processing timing references

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as LFXTAL054208RL3K indicate reel packaging while bulk options exist. Confirm that the required operating temperature range of -20°C to +70°C aligns with the application environment. Ensure the target circuit design accommodates the specified 10 pF load capacitance and 120 Ohm ESR to guarantee correct oscillation startup and frequency accuracy.

Selection Notes

Select this component when a 12 MHz fundamental frequency with high stability is required for space-constrained designs. The 3.2mm x 2.5mm package size suits applications where board real estate is limited compared to larger HC-49 packages. Consider the 100 uW drive level limit to prevent over-driving the crystal, which could affect longevity or frequency drift. This part is suitable for commercial grade environments rather than harsh industrial conditions requiring wider temperature ranges.

Part Context

This crystal belongs to the standard quartz oscillator family from IQD Frequency Products, designed for general-purpose electronic timing applications. It serves as a passive resonant element essential for establishing clock signals in digital systems. The product line emphasizes reliability and consistency in frequency performance across manufacturing batches.

Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 10 pF load capacitance, and 3.2x2.5mm SMD package dimensions. Verify that alternative components offer comparable ±10 ppm stability and similar ESR values to maintain circuit oscillation integrity.
