105-472J

Overview

The Delevan 105-472J is a fixed surface-mount RF inductor with a nominal inductance of 4.7 µH and a tolerance of ±1%. It features a maximum DC resistance of 3.1 Ohms and a rated current of 175 mA. The component utilizes an iron core and epoxy encapsulation, housed in a nonstandard 1010 package measuring approximately 2.54 mm by 2.54 mm with a height of 1.91 mm. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Epoxy encapsulated construction for mechanical stability
• Iron core design optimized for RF applications
• Surface mount form factor for automated assembly

Applications

• RF signal processing circuits
• General purpose inductive filtering
• High-frequency impedance matching networks

Procurement Notes

Verify RoHS compliance status as historical data indicates leaded variants may exist. Confirm the specific suffix or revision against the manufacturer's latest datasheet to ensure compatibility with modern environmental regulations. Cross-reference the DigiKey part number DN08472JTR for accurate ordering details and availability checks.

Selection Notes

Select this component for applications requiring precise 4.7 µH inductance in compact RF environments. The low current rating of 175 mA necessitates careful thermal management and circuit design to prevent saturation. Ensure the PCB footprint matches the nonstandard 1010 dimensions and verify that the 3.1 Ohm DC resistance aligns with the system's power loss constraints.

Part Context

This part belongs to the API Delevan 105 series of unshielded surface-mount inductors. These components are designed for general-purpose and RF uses, distinguishing themselves from higher-current power inductors like the 5500R series through their smaller physical size and lower current handling capabilities.

Replacement Considerations

The 105R-472J is a documented alternative variant within the same product family. Verify if the 'R' suffix denotes a specific packaging or material update before substitution.
