LFXTAL085850

Overview

The LFXTAL085850 is a surface-mount quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 30 MHz with a frequency tolerance of ±10 ppm and a frequency stability of ±50 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 3.2 mm x 2.5 mm and a seated height of 0.50 mm. The device supports an operating temperature range from -40°C to +125°C and accepts a maximum drive level of 100 µW.

Feature Summary

• High-temperature stability suitable for demanding industrial environments
• Compact surface-mount footprint for automated assembly
• Low equivalent series resistance for efficient signal transmission

Applications

• RF circuit timing references
• Industrial control systems
• Automotive electronics modules

Procurement Notes

Verify the specific frequency tolerance and stability requirements against the application datasheet before ordering. Confirm that the 100 µW drive level is compatible with the host oscillator circuit to prevent overdriving the crystal. Ensure the PCB layout accommodates the 3.2 mm x 2.5 mm SMD package dimensions and thermal constraints associated with the -40°C to +125°C operating range.

Selection Notes

Select this component when a 30 MHz reference is required in high-temperature applications exceeding standard commercial limits. The ±10 ppm tolerance provides precise frequency accuracy, while the ±50 ppm stability ensures reliability across the extended temperature range. Consider the 100 Ohm ESR when designing the load capacitance network to achieve oscillation stability.

Part Context

This part belongs to IQD's stable crystal series designed for RF applications. It represents a specialized offering within the broader LFXTAL family, distinguished by its ability to maintain performance at elevated temperatures up to 125°C. The manufacturer leverages extensive experience in frequency control to provide reliable components for critical electronic systems.

Replacement Considerations

Direct substitutes include other 30 MHz crystals with similar 10 pF load capacitance and SMD packages. Verify that any replacement matches the 100 Ohm ESR and ±10 ppm tolerance to ensure circuit compatibility.
