10M302J

Overview

The Gowanda Electronics 10M302J is a fixed, unshielded wirewound inductor with an inductance of 30 µH and a tolerance of ±5%. It features a maximum DC resistance of 3.3 Ohms and a current rating of 132 mA. The component utilizes a powdered iron core and is housed in an axial package measuring 2.413 mm in diameter and 6.35 mm in length. It operates within a temperature range of -55°C to 105°C and is tested at 2.5 MHz for Q factor performance.

Feature Summary

• Unshielded wirewound construction utilizing a powdered iron core
• Axial through-hole mounting configuration
• Designed for RF coil applications

Applications

• RF coil circuits
• Commercial off-the-shelf (COTS) applications

Procurement Notes

Verify the specific suffix designation against official Gowanda documentation to confirm compliance status and exact electrical tolerances. Ensure that the selected variant matches the required lead dimensions and thermal ratings for the intended assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate availability and authenticity before finalizing procurement orders.

Selection Notes

Select this component when an unshielded axial inductor is required for RF applications. Consider the 3.3 Ohm DC resistance and 132 mA current limit relative to circuit load requirements. Verify that the 30 µH value aligns with the target frequency response and that the axial form factor fits the PCB layout constraints.

Part Context

This component belongs to the Gowanda 10M series of general-purpose inductors. These parts are designed for commercial and industrial use, offering standard axial packaging. The series provides various inductance values with consistent physical dimensions, facilitating design-in processes for standard electronic assemblies requiring reliable magnetic components.

Replacement Considerations

The 10M302JLF is a RoHS-compliant version of this component. Verify if the non-LF suffix indicates a different compliance status or material composition. Ensure substitute parts maintain the same 30 µH inductance, 3.3 Ohm DCR, and axial footprint compatibility.
