LFXTAL051068

Overview

LFXTAL051068 is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 25 MHz with a load capacitance of 9pF and an equivalent series resistance (ESR) of 50 Ohms. The component exhibits a frequency tolerance of ±50ppm and stability of ±50ppm. Designed for surface mount applications, it features a 4-SMD, no-lead package measuring 3.2mm in length, 2.5mm in width, and 1.0mm in maximum height. The device supports operation within a temperature range of -20°C to +70°C.

Feature Summary

• Fundamental resonance mode operation ensures stable frequency generation.
• Compact 4-SMD no-lead footprint facilitates automated surface mount assembly.
• Integrated load capacitance specification simplifies circuit design requirements.

Applications

• Microcontroller clock source integration
• Communication module timing references
• Embedded system oscillator circuits

Procurement Notes

Verify the specific load capacitance requirement of 9pF against the target circuit design to ensure accurate frequency performance. Confirm that the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the intended application. Cross-reference the 4-SMD package dimensions with the PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a 25 MHz fundamental frequency is required with moderate stability specifications. The 9pF load capacitance suits circuits designed for lower capacitive loading compared to standard 18pF or 20pF crystals. Consider the 50 Ohm ESR value for drive level sensitivity analysis. Ensure the SMD package size fits within the spatial constraints of the target electronic assembly.

Part Context

This part belongs to the general quartz crystal category from IQD Frequency Products, focusing on passive frequency control elements. Unlike active oscillators such as TCXOs, this component requires an external oscillator circuit to function. It differs from higher-stability variants by offering standard ppm tolerances suitable for general-purpose digital logic timing rather than precision synchronization applications.

Replacement Considerations
