LFXTAL003156BULK

Overview

The LFXTAL003156BULK is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a standard frequency of 8 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component utilizes a through-hole HC-49 package, measuring 11.05 mm in length, 4.7 mm in width, and 4.1 mm in height. It features a load capacitance of 30 pF and a series resistance of 40 Ω. The device supports an operating temperature range from -20°C to +70°C and complies with RoHS and REACH standards.

Feature Summary

• Hermetically sealed construction using glass-to-metal seals within an inert atmosphere for environmental protection
• Resistance-welded leads integrated into a standard industry HC-49 two-pin package
• Fundamental parallel oscillation mode operation optimized for standard circuit integration

Applications

• General-purpose timing circuits requiring stable 8 MHz reference signals
• Microcontroller clock generation systems
• Industrial control equipment operating within standard commercial temperature ranges

Procurement Notes

Verify the specific suffix 'BULK' indicates bulk packaging rather than tape-and-reel configuration when ordering. Confirm that the HC-49 form factor aligns with existing PCB footprint requirements. Ensure the ±30 ppm tolerance meets system phase noise and jitter specifications. Validate compliance with local regulatory standards such as RoHS and REACH for intended market deployment.

Selection Notes

Select this component when a through-hole mounting solution is required for 8 MHz applications. The HC-49 package offers robust mechanical stability compared to surface-mount alternatives. Consider the 40 Ω series resistance for oscillator circuit loading calculations. Evaluate the -20°C to +70°C temperature range against environmental conditions to ensure reliable frequency stability throughout the operational lifecycle.

Part Context

This part belongs to the IQD Frequency Products quartz crystal family, specifically designed for general electronic timing applications. As a fundamental mode crystal, it provides precise frequency control for digital systems. The product line emphasizes reliability through hermetic sealing and standardized packaging formats suitable for automated and manual assembly processes.

Replacement Considerations

Direct substitutes must match the 8 MHz frequency, 30 pF load capacitance, and HC-49 package dimensions. Verify equivalent frequency tolerance (±30 ppm) and series resistance characteristics. Cross-reference manufacturer-specific parameters such as drive level sensitivity and aging rates to ensure circuit compatibility without modification.
