LFXTAL059539

Overview

The LFXTAL059539 is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 48 MHz with a load capacitance of 18 pF and an equivalent series resistance of 100 Ohms. The component provides a frequency tolerance of ±20 ppm and stability of ±30 ppm. It utilizes a 4-SMD, No Lead package measuring 5.00 mm in length, 3.20 mm in width, and 1.00 mm in height. The device supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Fundamental mode operation for precise timing generation
• Surface-mount design compatible with automated assembly processes
• Wide industrial temperature range capability

Applications

• Microcontroller clock sources
• Digital signal processing circuits
• Communication interface timing

Procurement Notes

Verify the specific package dimensions and electrical parameters against the official IQD Frequency Products datasheet prior to procurement. Confirm that the 4-SMD footprint matches the target PCB layout requirements. Ensure the operating temperature range meets the environmental specifications of the final application. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a 48 MHz fundamental frequency is required with tight initial tolerance. The 18 pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR value for drive level sensitivity. The SMD form factor is suitable for space-constrained designs requiring reliable surface mounting without through-hole constraints.

Part Context

This part belongs to the IQD Frequency Products quartz crystal portfolio, designed for general-purpose timing applications. It complements other surface-mount crystals in the lineup, offering standardized dimensions for easy integration into various electronic systems. The product line focuses on providing stable frequency references for digital logic and communication protocols.

Replacement Considerations

Direct substitutes include LFXTAL059537 (40 MHz) if frequency adjustment is acceptable. Verify pinout compatibility and thermal characteristics before swapping. No exact 48 MHz alternative is confirmed in the provided data.
