LFXTAL021675BULK

Overview

The LFXTAL021675BULK is a fundamental mode quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 10 MHz with an HC-49/US package configuration. The component features a load capacitance of 18 pF, a frequency tolerance of 30 PPM, and a frequency stability of 50 PPM. Designed for through-hole mounting, it utilizes radial termination style. This crystal is suitable for applications requiring standard frequency control within the specified operational parameters.

Feature Summary

• Fundamental mode quartz crystal operation
• HC-49/US through-hole package design
• Radial lead termination for PCB mounting

Applications

• General purpose timing circuits
• Microcontroller clock sources
• Digital logic synchronization

Procurement Notes

Verify availability status as distribution channels may indicate regional sales restrictions or discontinuation. Confirm that the HC-49/US package dimensions align with target PCB footprint requirements. Ensure the 18 pF load capacitance matches the oscillator circuit design specifications to guarantee accurate frequency performance.

Selection Notes

Select this component when a 10 MHz fundamental frequency is required in a standard through-hole format. The 30 PPM tolerance provides adequate precision for general digital systems. Consider the HC-49/US size constraints and verify that the 50 PPM stability meets the system's long-term timing accuracy needs without additional temperature compensation.

Part Context

This part belongs to the IQD LFXTAL series of quartz crystals. It represents a standard discrete resonator component used in electronic assemblies where precise timekeeping or clock generation is necessary. The HC-49/US form factor is widely recognized in legacy and industrial electronics for its robust mechanical structure and ease of manual or automated insertion.

Replacement Considerations

Cross-reference with other 10 MHz HC-49/US crystals from manufacturers such as TXC, ECS, or NDK. Verify equivalent electrical parameters including load capacitance, ESR, and drive level before substitution.
