LFXTAL016788

Overview

The LFXTAL016788 is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 6 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component features a 30 pF load capacitance and an equivalent series resistance (ESR) of 60 Ω maximum. It utilizes the HC-49/4HSMX SMD package, measuring 11.4 mm in length, 4.9 mm in width, and 4.3 mm in height. The device supports a operating temperature range from -10°C to +60°C.

Feature Summary

• Hermetically sealed construction using resistance welding in an inert atmosphere with glass-to-metal seals for environmental protection.
• Standard two-lead HC-49 form factor designed for reliable surface mount technology (SMT) assembly.
• Capable of withstanding standard lead-free reflow soldering profiles without performance degradation.

Applications

• Industrial data acquisition gateways requiring stable external clock sources.
• Microcontroller systems utilizing low-speed serial communication interfaces such as UART or CAN bus.
• Sensor acquisition modules where precise timing is required for signal processing.

Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, such as bulk or reel quantities, as these affect handling procedures. Ensure that the selected variant complies with RoHS and REACH directives if required by your manufacturing standards. Cross-reference the manufacturer part number with distributor catalogs to confirm current availability and technical documentation status before finalizing procurement plans.

Selection Notes

Select this component when a 6 MHz fundamental frequency is required for microcontroller or peripheral clocking. The 30 pF load capacitance must be matched with appropriate external capacitors on the PCB to achieve accurate frequency operation. Consider the ±50 ppm stability and -10°C to +60°C temperature range to ensure compatibility with the intended operational environment and thermal constraints.
