LFXTAL012482BULK

Overview

The LFXTAL012482BULK is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 40.685 MHz with a frequency tolerance of ±30 ppm and a stability of ±50 ppm. The component features a load capacitance of 30 pF and an equivalent series resistance (ESR) typical for this series. It utilizes the HC-49/U through-hole package, measuring 11.05 mm in length, 4.70 mm in width, and up to 13.49 mm in height. The device supports a standard drive level of 1 mW and functions within an operating temperature range of -10°C to +60°C.

Feature Summary

• Fundamental resonance mode operation for stable timing reference
• HC-49/U through-hole package design for standard PCB mounting
• Compliant with RoHS3 environmental standards

Applications

• General purpose clock generation circuits
• Microcontroller system timing references
• Industrial control equipment oscillators

Procurement Notes

Verify the specific suffix 'BULK' against official IQD documentation to confirm packaging configuration, as distributor listings may vary. Confirm that the HC-49/U form factor matches the target footprint requirements. Ensure the ±30 ppm tolerance meets the system's phase noise and jitter specifications. Cross-reference the manufacturer part number directly with IQD Frequency Products to avoid substitution errors with similar frequency variants.

Selection Notes

Select this component when a fundamental mode crystal at 40.685 MHz is required for through-hole assembly. The HC-49/U package offers robust mechanical stability compared to surface mount alternatives. Consider the ±50 ppm stability limit for applications sensitive to temperature-induced drift. Verify that the circuit impedance matches the 30 pF load capacitance specification to ensure accurate frequency performance.

Part Context

This part belongs to the IQD LFXTAL series of general-purpose quartz crystals. These components are designed for commercial and industrial applications requiring reliable frequency control. The manufacturer, IQD Frequency Products, specializes in timing solutions including crystals and oscillators. This specific model represents a standard leaded crystal variant commonly used in legacy and modern electronic designs.

Replacement Considerations

Direct substitutes must match the 40.685 MHz frequency, 30 pF load capacitance, and HC-49/U package dimensions. Verify ESR compatibility and drive level specifications. Check for equivalent frequency tolerance and stability ratings. Ensure the replacement component maintains the same fundamental mode operation and temperature range.
