LFXTAL015055

Overview

The LFXTAL015055 is a quartz crystal resonator manufactured by IQD Frequency Products, operating at a standard frequency of 16 MHz. It features a frequency tolerance of ±30 ppm and a stability of ±50 ppm. The component utilizes a 20 pF load capacitance and exhibits an equivalent series resistance (ESR) of 40 Ohms. Designed for surface mount applications, it employs the HC49/4HSMX package with dimensions of 13.40 mm in length, 4.90 mm in width, and a maximum height of 4.30 mm. It operates within a temperature range of -10°C to +60°C.

Feature Summary

• Surface mount design utilizing the HC49/4HSMX package format
• Quartz crystal construction for stable oscillation
• Supports base mode operation

Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Digital logic timing references

Procurement Notes

Verify the specific package variant against the datasheet, as HC49/4HSMX denotes a surface mount configuration distinct from through-hole HC49/U units. Confirm that the operating temperature range of -10°C to +60°C aligns with the environmental requirements of the target application. Ensure the 20 pF load capacitance matches the circuit design specifications to maintain accurate frequency performance.

Selection Notes

Select this component when a 16 MHz surface mount crystal is required with moderate stability needs. The HC49/4HSMX package offers a compact footprint suitable for space-constrained designs while maintaining compatibility with standard SMT assembly processes. Consider the -10°C to +60°C operating range to ensure reliability under expected thermal conditions.

Part Context

This part belongs to the IQD Frequency Products quartz crystal portfolio, specifically designed for general electronic applications requiring precise timing. The HC49/4HSMX series provides a transition from traditional through-hole packages to surface mount technology, facilitating automated assembly and reduced board space usage.

Replacement Considerations

Cross-reference with other 16 MHz SMD crystals in the HC49/4HSMX form factor. Verify that substitute components match the 20 pF load capacitance and 40 Ohm ESR specifications to ensure circuit compatibility.
