10M472KLF

Overview

The 10M472KLF is a fixed axial leaded inductor manufactured by Gowanda Electronics. It features an unshielded wirewound construction with a ferrite core, designed for general-purpose applications. The component has a nominal inductance of 47 µH and a tolerance of ±10%. It supports a maximum current rating of 110 mA and exhibits a maximum DC resistance of 4.5 Ohms. The device operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Unshielded wirewound design suitable for non-critical magnetic environments
• Axial through-hole mounting configuration for standard PCB integration
• Ferrite core construction optimized for RF inductor applications

Applications

• Radio frequency filtering circuits
• General-purpose AC electronic equipment
• Power choke applications requiring low current handling

Procurement Notes

Verify the specific suffix 'LF' indicates lead-free compliance as per manufacturer documentation. Confirm that the unshielded nature aligns with system EMC requirements. Ensure the 110 mA current limit is sufficient for the intended circuit load to prevent saturation or thermal issues during operation.

Selection Notes

Select this component when axial mounting is required and magnetic shielding is not necessary. Consider the 4.5 Ohm DC resistance impact on voltage drop. Compare against shielded alternatives if electromagnetic interference suppression is critical for the target application environment.

Part Context

This part belongs to the Gowanda 10M series of high-current axial chokes. It utilizes toroidal geometry for efficient magnetic flux containment despite the lack of external shielding. The series is engineered for reliability in demanding industrial and aerospace sectors where consistent performance across wide temperature ranges is essential.

Replacement Considerations

The 10M472K is a traditional leaded variant of this component. Verify compatibility regarding lead content and regulatory compliance before substitution. Ensure physical dimensions and pin spacing match the existing footprint to avoid mechanical rework.
