10M271KLF

Overview

The 10M271KLF is a fixed wirewound inductor manufactured by Gowanda Electronics, designed for radio frequency applications. It features an unshielded construction with a powdered iron-ferrite core material. The component provides a nominal inductance of 2.7 µH and exhibits a maximum DC resistance of 550 mΩ. It supports a maximum rated current of 355 mA and achieves a minimum quality factor of 37 at a test frequency of 7.9 MHz. The device utilizes an axial lead configuration for through-hole mounting.

Feature Summary

• Utilizes a powdered iron-ferrite core to support radio frequency operations
• Features an unshielded wirewound design for general RF circuit integration
• Provides axial lead termination for standard through-hole PCB assembly

Applications

• Radio frequency signal processing circuits
• General purpose RF filtering applications
• Broadband power RF transformer implementations

Procurement Notes

Verify the specific RoHS compliance status and lead content requirements against project specifications, as Gowanda offers both traditional leaded and lead-free variants within the 10M series. Confirm that the axial package dimensions align with the target board layout. Ensure the 355 mA current rating meets the operational load requirements without exceeding thermal limits during continuous use.

Selection Notes

Select this component when an unshielded axial inductor is required for RF frequencies around 7.9 MHz. The 2.7 µH value and 37 Q factor make it suitable for narrowband tuning or impedance matching tasks. Consider the 550 mΩ DC resistance impact on circuit efficiency. Verify that the lack of shielding does not cause interference with nearby sensitive components in the final assembly.

Part Context

This part belongs to the 10M series of standard RF inductors from Gowanda Electronics. The series includes various inductance values ranging from 0.27 µH to higher capacities, all sharing similar axial lead construction and unshielded characteristics. The 'LF' suffix typically denotes lead-free compliance, distinguishing it from the standard 10M271K variant which may contain lead.

Replacement Considerations

The 10M271K serves as the primary alternative within the same product line, differing potentially in lead composition rather than electrical performance. Cross-reference the 10M221KLF if a slightly lower inductance value is acceptable. No direct cross-manufacturer substitutes are documented in the provided data.
