15M271K

Overview

The 15M271K is a fixed inductor manufactured by Gowanda Electronics, designed for general-purpose applications. It features an unshielded construction with a molded body and axial leads. The component has a nominal inductance of 3 µH and a maximum DC resistance of 1.2 Ohms. It supports a current rating of 385 mA and operates within a temperature range of -55 °C to +125 °C. The device utilizes a phenolic core material and is available in a standard axial package configuration.

Feature Summary

• Unshielded design suitable for flexible circuit layout
• Molded construction for mechanical stability
• Axial lead configuration for through-hole mounting

Applications

• RF coil circuits
• General purpose filtering
• Signal processing networks

Procurement Notes

Verify the exact inductance value against the specific datasheet revision, as conflicting data sources indicate variations between 2.7 µH and 3 µH for similar part numbers. Confirm RoHS compliance status and lead material specifications prior to integration. Ensure the axial package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component when an unshielded axial inductor is required for low-frequency RF or general signal applications. Consider the 385 mA current limit and 1.2 Ohm DC resistance for power budget calculations. The phenolic core offers standard performance characteristics suitable for non-critical timing or filtering tasks.

Part Context

This part belongs to Gowanda Electronics' line of molded unshielded RF coils. These components are engineered for reliability in aerospace, defense, and medical sectors. The axial form factor distinguishes it from surface-mount alternatives, providing robust mechanical attachment for environments requiring high vibration resistance.

Replacement Considerations

Direct substitutes include other Gowanda axial inductors with matching 3 µH inductance and similar current ratings. Verify that replacement parts maintain the same axial lead spacing and overall length to ensure compatibility with existing assembly tooling and board layouts.
