LFXTAL010043BULK

Overview

The LFXTAL010043BULK is a quartz crystal manufactured by IQD Frequency Products, designed for high-frequency applications. It operates at a nominal frequency of 12.0 MHz with a load capacitance of 30 pF. The component features a frequency tolerance of ±30 ppm and a frequency stability of 50 ppm. It supports a drive level of 1 mW and functions within an operating temperature range of -10°C to +60°C. The unit utilizes a standard HC-49 package with radial termination style, measuring 13.4 mm in length, 4.9 mm in width, and 4.3 mm in height.

Feature Summary

• Hermetically sealed in an inert atmosphere with glass-to-metal seals on leads
• Industry standard leaded package construction
• Resistance welded design for reliability

Applications

• High-frequency electronic circuits
• Clock generation systems
• Microcontroller oscillator interfaces

Procurement Notes

Verify the specific packaging configuration against project requirements, as bulk packaging differs from tape and reel options. Confirm that the radial termination style aligns with the target PCB layout and assembly processes. Ensure the operating temperature range meets environmental specifications. Cross-reference the exact part number suffix to guarantee compatibility with existing supply chains and avoid substitution errors during procurement.

Selection Notes

Select this component when a 12.0 MHz fundamental frequency is required with moderate stability. The HC-49 package suits through-hole mounting designs. Consider the 30 pF load capacitance for circuit matching. Evaluate the drive level limits to prevent over-driving the crystal. Assess the temperature range suitability for the intended operational environment before finalizing the design.

Part Context

This part belongs to the IQD Frequency Products quartz crystal lineup, which provides passive frequency control components. The LFXTAL series typically includes various frequencies and packages. This specific model represents a standard through-hole option. It complements active oscillators like TCXOs and VCXOs offered by the manufacturer. The product serves as a foundational element for timing references in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other HC-49 crystals with identical 12.0 MHz frequency and 30 pF load capacitance. Verify equivalent tolerance and stability ratings. Check for compatible drive levels and temperature ranges. Ensure the replacement maintains the same physical dimensions for board fitment.
