LFXTAL026902BULK

Overview

The LFXTAL026902BULK is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 8.192 MHz with a load capacitance of 16 pF. The component features a frequency stability of ±50 ppm and an initial tolerance of ±20 ppm. It utilizes the HC49SM package style for SMD mounting. The drive level is specified at 0.5 mW, and the equivalent series resistance (ESR) is typically low. This part is designed for standard commercial temperature ranges.

Feature Summary

• Surface-mount construction in a compact HC49SM package
• Fundamental mode operation at 8.192 MHz
• Hermetically sealed glass-to-metal structure

Applications

• Microcontroller clock sources
• Communication interface timing
• General-purpose digital circuitry

Procurement Notes

Verify the specific suffix 'Bulk' indicates loose packaging rather than tape-and-reel configuration when planning assembly line integration. Confirm that the HC49SM footprint matches the target PCB design constraints. Ensure the 16 pF load capacitance aligns with the oscillator circuit requirements to maintain the specified ±50 ppm stability. Check for any RoHS compliance documentation if required by the manufacturing environment.

Selection Notes

Select this component when a standard 8.192 MHz reference is required in a surface-mount form factor. The HC49SM package offers a balance between size and robustness compared to smaller SMD crystals. Consider the ±20 ppm initial tolerance if tighter frequency accuracy is needed, as this part does not offer tighter tolerances. Verify that the 0.5 mW drive level is sufficient for the application without risking overdriving the crystal.

Part Context

This part belongs to the IQD LFXTAL series of quartz crystals, which are widely used in consumer electronics and industrial equipment. IQD Frequency Products specializes in frequency control solutions, offering both through-hole and surface-mount options. The LFXTAL026902BULK represents a standard industry frequency suitable for UART, SPI, and I2C bus timing applications where precise clock synchronization is necessary.

Replacement Considerations

Direct substitutes include other manufacturers' HC49SM crystals with identical 8.192 MHz frequency, 16 pF load capacitance, and similar stability ratings. Ensure replacement parts match the physical dimensions and pin spacing of the original HC49SM package. Verify that alternative components meet the same electrical specifications regarding drive level and ESR to ensure circuit compatibility.
