10M272KLF

Overview

The 10M272KLF is a fixed wirewound inductor manufactured by Gowanda Electronics. It features an unshielded axial leaded construction with a powdered iron-ferrite core. The nominal inductance is 27 µH with a tolerance of ±10%. The component has a maximum DC resistance of 3.5 Ω and a self-resonant frequency of 20 MHz. It supports a maximum rated current of 135 mA and operates within a temperature range of -55 °C to 125 °C.

Feature Summary

• Unshielded molded axial design for general RF applications
• Powdered iron-ferrite core material
• RoHS compliant manufacturing

Applications

• RF Inductor circuits
• General purpose filtering

Procurement Notes

Verify the specific suffix 'LF' confirms RoHS compliance status as per manufacturer documentation. Confirm that the axial lead configuration matches the target PCB layout requirements. Ensure the 135 mA current rating and 3.5 Ω DC resistance are sufficient for the intended circuit load conditions before finalizing procurement.

Selection Notes

Select this component when an unshielded axial inductor is required for RF applications. The 27 µH value and 10% tolerance suit standard filtering needs. Consider the 20 MHz self-resonant frequency limit for high-frequency operation. The 135 mA current rating defines the maximum continuous DC bias capability.

Part Context

This part belongs to the Gowanda Electronics line of fixed wirewound inductors. It utilizes a molded unshielded coil structure typical for through-hole mounting. The designation indicates a 27 µH nominal value with standard tolerance, distinct from shielded or surface-mount variants in the broader catalog.

Replacement Considerations

Direct substitutes must match the 27 µH inductance, 135 mA current rating, and axial package dimensions. Verify core material compatibility if Q-factor is critical.
