LFXTAL036401

Overview

The LFXTAL036401 is a quartz crystal manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a nominal frequency of 12 MHz with a frequency tolerance of ±20 ppm and a stability of ±50 ppm. The component utilizes an 18 pF load capacitance and features a maximum equivalent series resistance (ESR) of 90 Ohms. It is housed in a compact 4-SMD, no-lead package, specifically the CFPX-104 series format, measuring 5 mm by 3.2 mm.

Feature Summary

• Surface-mount design compatible with automated assembly processes
• Hermetically sealed quartz resonator structure
• Standardized footprint for PCB integration

Applications

• Clock signal generation for microprocessors
• Timing reference for communication interfaces
• Frequency control in consumer electronics

Procurement Notes

Verify the specific lot code and manufacturing date against the latest IQD Frequency Products documentation to ensure compliance with current RoHS directives and material specifications. Confirm that the 4-SMD package dimensions align with the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 12 MHz timing source is required in a space-constrained surface-mount environment. Ensure the circuit design accommodates the specified 18 pF load capacitance to maintain the stated ±20 ppm frequency tolerance. Evaluate the 90 Ohm ESR limit against the oscillator circuit's drive level requirements to prevent over-driving the crystal.

Part Context

This part belongs to the CFPX-104 series of quartz crystals from IQD Frequency Products. It serves as a fundamental frequency-determining element within electronic circuits, providing stable oscillation frequencies for digital systems. The series is characterized by its small physical profile and reliability in standard operating temperature ranges.

Replacement Considerations

Direct replacements must match the 12 MHz frequency, 18 pF load capacitance, and 4-SMD package dimensions. Verify that substitute components meet the same ±20 ppm tolerance and ESR specifications to ensure circuit compatibility without redesign.
