LFXTAL003166BULK

Overview

The IQD Frequency Products LFXTAL003166BULK is a surface-mount quartz crystal resonator operating at a nominal frequency of 10 MHz. It features a frequency tolerance of ±30ppm and stability of ±50ppm with a load capacitance of 16pF. The component utilizes an HC-49/US package (HC49/4H SMX) with dimensions of 11.40mm x 3.80mm x 4.30mm max. It operates in fundamental mode with an ESR of 40 Ohms across a temperature range of -10°C to +60°C.

Feature Summary

• Surface mount design in standard HC-49/US form factor
• Fundamental mode operation for stable timing signals
• Precision frequency control with low equivalent series resistance

Applications

• General purpose timing circuits
• Microcontroller clock sources
• Communication equipment oscillators

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation, as bulk packaging variants may differ from reel or cut-tape options. Confirm that the HC-49/4H SMX designation matches the required footprint for PCB layout. Ensure the temperature range and load capacitance align with the target circuit design requirements before finalizing procurement.

Selection Notes

Select this component when a standard surface-mount crystal with HC-49/US dimensions is required for 10 MHz applications. The ±30ppm tolerance suits general timing needs rather than high-precision references. Consider the 40 Ohm ESR value for oscillator circuit compatibility. Verify that the -10°C to +60°C operating range meets the environmental conditions of the intended application.

Part Context

This part belongs to the IQD HC49/4HSMX series of surface-mount crystals. It represents a transition from traditional through-hole HC-49/U packages to modern SMD manufacturing processes while maintaining similar physical footprints. The product line focuses on providing reliable frequency control solutions for consumer and industrial electronics requiring standardized mounting profiles.

Replacement Considerations

Direct substitutes must match the 10 MHz frequency, 16pF load capacitance, and HC-49/US package dimensions. Verify equivalent ESR values and frequency stability specifications. Cross-reference with other manufacturers offering SMD crystals in the HC-49/4H SMX format to ensure pin compatibility and thermal performance alignment.
