LFXTAL032341B

Overview

The LFXTAL032341B is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 10 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm across the operating temperature range of -20°C to +70°C. The component utilizes an HC-49/4H surface mount package, featuring a load capacitance of 18 pF and a maximum equivalent series resistance (ESR) of 40 Ω. It supports a maximum drive level of 500 µW and exhibits typical aging of ±5 ppm per year.

Feature Summary

• Hermetically sealed in an inert atmosphere using glass-to-metal seals on leads for environmental protection
• Resistance welded construction ensures long-term reliability and stable electrical performance
• Lead wires mounted onto a plastic former to create a gull-wing mount configuration

Applications

• General purpose timing circuits requiring 10 MHz reference
• Industrial control systems operating within standard temperature ranges
• Consumer electronics utilizing surface mount assembly processes

Procurement Notes

Verify that the specific order quantity matches the bulk packaging designation associated with this part number. Confirm that the required frequency tolerance of ±30 ppm aligns with the circuit design specifications before finalizing procurement. Ensure compatibility with the HC-49/4H footprint dimensions during the manufacturing integration phase.

Selection Notes

Select this component when a 10 MHz fundamental frequency is required with moderate stability needs. The HC-49/4H SMD form factor is suitable for applications where space constraints allow for larger surface mount crystals compared to miniature packages. Consider the 18 pF load capacitance requirement for oscillator circuit design to ensure accurate frequency generation.
