LFXTAL056463

Overview

The LFXTAL056463 is a fundamental parallel-mode quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 25 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms. The component offers a frequency tolerance of ±30 ppm and stability of ±50 ppm. Designed for through-hole mounting, it utilizes the HC-49/US package with dimensions of 11.05 mm length, 4.7 mm width, and 4.1 mm height. It supports a drive level of 500 µW and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Fundamental parallel resonance mode operation
• HC-49/US through-hole package configuration
• High frequency stability and tolerance specifications

Applications

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

Procurement Notes

Verify that the specific order matches the HC-49/US through-hole package type, as surface-mount variants exist within the same product family. Confirm the required load capacitance aligns with the circuit design's 18 pF specification to ensure accurate frequency performance. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the application's thermal requirements.

Selection Notes

Select this component when a standard through-hole quartz crystal is required for 25 MHz applications. The HC-49/US form factor suits legacy or high-reliability board layouts where surface-mount options are unsuitable. Consider the 40 Ohm ESR value for oscillator circuit compatibility. Evaluate the ±30 ppm tolerance against the system's timing accuracy needs before finalizing the part selection.

Part Context

This component belongs to IQD Frequency Products' extensive portfolio of discrete quartz crystals. The LFXTAL series provides reliable timing solutions for various electronic industries. The LFXTAL056463 specifically addresses demand for standard 25 MHz frequencies in through-hole designs. It complements other IQD offerings like TCXOs and VCXOs for more complex timing requirements.

Replacement Considerations

Direct substitutes include other 25 MHz HC-49/US crystals with matching 18 pF load capacitance and similar ESR values. Verify pin compatibility and physical dimensions when cross-referencing alternative manufacturers. Ensure frequency tolerance and stability metrics meet or exceed the original specifications.
