LFXTAL059627

Overview

The LFXTAL059627 is a quartz crystal resonator manufactured by IQD Frequency Products. It operates at a fundamental frequency of 38.4 MHz with a frequency tolerance of ±15 ppm and a load capacitance of 10 pF. The component features an equivalent series resistance (ESR) of 100 Ohms and utilizes a 4-SMD, No Lead package measuring 2.0 mm x 1.6 mm x 0.8 mm. It supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Hermetically sealed construction using glass-to-metal seals within an inert atmosphere for environmental stability.
• Surface-mount design compatible with automated pick-and-place assembly processes.
• Fundamental mode operation providing stable oscillation for clock signal generation.

Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Digital logic synchronization

Procurement Notes

Verify the specific package dimensions and lead configuration against the official datasheet before integration. Confirm that the load capacitance requirements of the host oscillator circuit align with the 10 pF specification to ensure accurate frequency performance. Check for RoHS compliance status in the latest documentation.

Selection Notes

Select this component when a compact surface-mount footprint is required for high-frequency applications. The 38.4 MHz frequency is suitable for baud rate generation in serial communications. Ensure the PCB layout accommodates the 2.0 mm x 1.6 mm case size and provides adequate clearance for soldering.

Part Context

This part belongs to the IQD LFXTAL series of quartz crystals. It represents a standard industry solution for replacing through-hole components with surface-mount equivalents. The product line focuses on providing reliable timing references for consumer electronics and industrial control systems.

Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 10 pF load capacitance, and 4-SMD no-lead package dimensions. Verify ESR compatibility with the driving circuit. Cross-reference with other manufacturers offering HC-49/S or similar small SMD crystal variants if availability is constrained.
