LFXTAL075997

Overview

The LFXTAL075997 is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 9.9 MHz with a load capacitance of 12 pF. The component features a frequency tolerance of ±40 ppm and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, No Lead package configuration. The device is designed for general-purpose timing applications requiring stable oscillation within standard operating conditions.

Feature Summary

• Surface-mount quartz crystal design for automated assembly
• Fundamental mode operation at 9.9 MHz
• Integrated 12 pF load capacitance specification
• Standard 4-SMD no-lead package footprint

Applications

• General-purpose microcontroller clock sources
• Consumer electronics timing circuits
• Industrial control system oscillators
• Communication device reference clocks

Procurement Notes

Verify the specific package dimensions and pinout compatibility against the target PCB layout before ordering. Confirm that the 12 pF load capacitance matches the oscillator circuit requirements of the host device. Ensure the ±40 ppm tolerance meets the system timing accuracy specifications. Check for any recent manufacturing changes or obsolescence notices from IQD Frequency Products.

Selection Notes

Select this component when a 9.9 MHz fundamental frequency is required for digital logic timing. The 4-SMD package offers space efficiency compared to through-hole alternatives. Consider the 50 Ohm ESR value for driving capability requirements. Evaluate if the ±40 ppm stability is sufficient for the application's phase noise and jitter constraints relative to higher-precision options.

Part Context

This part belongs to the IQD Frequency Products quartz crystal portfolio, which provides various frequency control solutions. The LFXTAL series typically includes both through-hole and surface-mount variants. This specific model represents a compact SMD option suitable for modern printed circuit board designs where space conservation and automated placement are priorities.

Replacement Considerations

Direct substitutes must match the 9.9 MHz frequency, 12 pF load capacitance, and 4-SMD package dimensions. Verify equivalent ESR and tolerance ratings to ensure circuit performance parity. Cross-reference with other manufacturers offering similar SMD crystal footprints if IQD supply is unavailable.
