10M471JLF

Overview

The Gowanda Electronics 10M471JLF is a fixed, unshielded wirewound inductor designed for general-purpose and RF applications. It features an axial leaded package with a powdered iron core. The component provides a nominal inductance of 4.7 µH with a tolerance of ±5%. It supports a maximum DC current of 230 mA and has a maximum DC resistance of 1.2 Ω. The self-resonant frequency is specified at 75 MHz, and it operates within a temperature range of -55 °C to +125 °C.

Feature Summary

• Unshielded wirewound construction utilizing a powdered iron core for stable performance
• Axial through-hole packaging suitable for standard PCB mounting techniques
• High self-resonant frequency capability for effective RF circuit integration

Applications

• RF coil circuits requiring specific inductance values
• General-purpose filtering applications in electronic systems
• Aerospace and defense equipment relying on high-performance magnetics

Procurement Notes

Verify the exact RoHS compliance status and datasheet revisions directly with Gowanda Electronics or authorized distributors before procurement. Confirm that the axial lead dimensions and thermal characteristics align with your assembly process requirements. Ensure the 230 mA current rating meets the operational demands of your specific circuit design to prevent saturation or overheating issues during long-term use.

Selection Notes

Select this component when an unshielded axial inductor with a 4.7 µH value is required for RF or general-purpose applications. Consider the 1.2 Ω DC resistance and 230 mA current limit against your circuit's power constraints. The wide operating temperature range makes it suitable for demanding environments, provided the unshielded nature does not interfere with nearby sensitive components.

Part Context

This part belongs to the Gowanda 10M series of traditional leaded RF inductors. These components are manufactured for aerospace, defense, and medical sectors where reliability is critical. The series offers various inductance values using similar axial packages, allowing designers to maintain consistent mechanical footprints across different circuit designs while varying electrical parameters.

Replacement Considerations

Direct substitutes include other Gowanda 10M series parts with identical electrical specifications but different inductance values if parameter adjustment is acceptable. Cross-brand replacements must match the 4.7 µH inductance, 230 mA current rating, 1.2 Ω DCR, and axial form factor. Verify that alternative manufacturers provide comparable self-resonant frequencies and temperature stability for RF applications.
