10M473J

Overview

The Gowanda Electronics 10M473J is a general-purpose, unshielded molded axial inductor designed for RF coil applications. It features a nominal inductance of 470 µH with a tolerance of ±5%. The component utilizes a powdered iron core and exhibits a maximum DC resistance of 42 Ohms. It supports a maximum rated current of 36 mA and operates within a temperature range of -55 °C to +105 °C. The device has an axial lead configuration with a lead diameter of approximately 0.51 mm.

Feature Summary

• Unshielded molded construction suitable for RF coil applications
• Powdered iron core material for stable magnetic performance
• Axial leaded package design for through-hole mounting

Applications

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

Procurement Notes

Verify the specific manufacturer datasheet for the 10M473J to confirm RoHS compliance status and lead finish specifications. Ensure that the required operating current does not exceed the 36 mA rating to prevent thermal issues. Confirm that the physical dimensions align with the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a high-inductance value of 470 µH is required in a compact axial form factor. Consider the 42 Ohm DC resistance and 36 mA current limit during circuit design to ensure proper signal integrity. The unshielded nature requires adequate spacing from sensitive components to minimize electromagnetic interference coupling.

Part Context

This part belongs to the Gowanda 10M series of wirewound, molded inductors. The series offers various inductance values ranging from 0.1 µH to higher capacities, all sharing similar axial packaging and core materials. This specific model represents a mid-to-high inductance option within the standard general-purpose lineup.

Replacement Considerations

Cross-reference with other Gowanda 10M series variants such as 10M470K or 10M510J if slight tolerance adjustments are acceptable. Verify that substitute parts maintain the same axial lead pitch and overall envelope dimensions for direct board replacement.
