LFXTAL057997

Overview

The LFXTAL057997 is a surface-mount quartz crystal oscillator manufactured by IQD Frequency Products. It operates at a fundamental frequency of 16 MHz with a frequency tolerance of ±10 ppm and stability of ±20 ppm. The component requires a load capacitance of 10 pF and exhibits an equivalent series resistance (ESR) of 70 Ohms. Designed for the CFPX-180 series, it utilizes a 4-SMD, no-lead package measuring 3.20 mm in length, 2.50 mm in width, and 0.80 mm in height. It supports a wide operating temperature range from -40°C to +85°C and is RoHS compliant.

Procurement Notes

Verify the specific ordering suffix required for your manufacturing process, as this part number is available in various packaging formats including cut tape, reel, and Digi-Reel options. Confirm that the selected variant matches the exact quantity constraints of your production line. Ensure compatibility with standard reflow soldering profiles defined for lead-free assemblies. Cross-reference the manufacturer's latest documentation to confirm current availability status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a stable 16 MHz reference is required for space-constrained designs. The 10 pF load capacitance specification must align with the driving circuit's design parameters to ensure accurate frequency performance. Consider the 70 Ohm ESR value when evaluating power consumption and drive level limitations. The 4-SMD package offers a smaller profile compared to traditional through-hole crystals, making it suitable for modern high-density electronic applications requiring robust thermal performance.

Part Context

This device belongs to the CFPX-180 series of surface-mount quartz crystals from IQD Frequency Products. The series is engineered for general-purpose timing applications where reliability and compact size are prioritized. These components are widely utilized in consumer electronics, industrial control systems, and telecommunications equipment. The LFXTAL057997 specifically addresses the demand for cost-effective, high-performance oscillators that meet stringent industry standards for frequency accuracy and environmental resilience.

Replacement Considerations

Direct substitutes include other 16 MHz SMD crystals with matching 10 pF load capacitance and similar physical dimensions. Verify that alternative parts maintain the same ±10 ppm tolerance and operate within the -40°C to +85°C range. Ensure the replacement component supports fundamental mode operation and has comparable ESR characteristics to prevent drive level issues.
