10M271K

Overview

The 10M271K is an unshielded wirewound inductor manufactured by Gowanda Electronics, designed for high-frequency applications. It features a nominal inductance of 2.7 µH with a tolerance of 10%. The component utilizes a phenolic core and offers a maximum DC resistance of 550 mΩ. It supports a maximum current rating of 355 mA and achieves a self-resonant frequency of 100 MHz. The device operates within a temperature range of -55 °C to +125 °C and employs axial leaded termination.

Feature Summary

• Unshielded wirewound construction suitable for high-frequency environments
• Phenolic core design providing stable inductance characteristics
• Axial leaded configuration for through-hole mounting

Applications

• High-frequency RF circuits
• General-purpose filtering applications
• Industrial electronic systems

Procurement Notes

Verify RoHS compliance status as the standard 10M series may contain lead; confirm specific ordering suffixes if lead-free requirements are mandatory. Ensure axial lead dimensions match PCB layout constraints. Cross-reference datasheet specifications against system thermal limits to guarantee operation within the specified temperature range.

Selection Notes

Select this component when unshielded performance is acceptable to minimize size and cost while maintaining high-frequency stability. The 2.7 µH value and 355 mA rating suit moderate power RF stages. Consider the 100 MHz self-resonant frequency limit for signal bandwidth requirements before finalizing the design.

Part Context

This part belongs to Gowanda’s standard RF inductor line, characterized by molded or wound constructions for demanding sectors. The 10M series specifically targets general-purpose and RF uses, offering reliable performance in aerospace, defense, and industrial markets where consistent magnetic properties are critical.

Replacement Considerations

Consult official Gowanda documentation for direct substitutes within the 10M series or alternative SML variants. Verify that any replacement matches the 2.7 µH inductance, 355 mA current rating, and axial package form factor.
