1945-17G

Fixed Inductors Overview

The Delevan 1945-17G is a fixed axial leaded RF inductor with an inductance of 56 µH and a tolerance of ±2%. It features a maximum DC resistance of 3.99 Ohms and a rated current of 265 mA. The component has a self-resonant frequency of 15.2 MHz and operates within a temperature range of -55°C to 125°C. Its physical dimensions are 4.90 mm in diameter by 11.35 mm in length, utilizing an unshielded molded construction.

Fixed Inductors Feature Summary

• Unshielded molded coil design for RF applications
• Axial lead termination for through-hole PCB mounting
• High Q factor performance at specified test frequencies

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• General purpose inductive components in electronic assemblies

Fixed Inductors Procurement Notes

Verify the specific suffix 'G' corresponds to the required 2% tolerance and 56 µH value, as the 1945 series contains multiple variants. Confirm RoHS status, as API Delevan documentation indicates this series may not be RoHS compliant. Ensure the axial package size matches the target PCB footprint constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a 56 µH inductance with tight 2% tolerance is required for RF environments. The unshielded design necessitates careful layout consideration to minimize electromagnetic interference with adjacent traces. Verify that the 265 mA current rating meets the operational requirements of the specific circuit application.

Fixed Inductors Part Context

This part belongs to the Delevan 1945 series of fixed RF inductors. These components are characterized by their molded construction and axial leads, designed for reliable performance in radio frequency circuits. The series offers various inductance values and tolerances to suit different filtering and tuning needs.

Fixed Inductors Replacement Considerations

Direct substitutes include other Delevan 1945 series parts with identical electrical parameters but different packaging or tolerance suffixes. Cross-brand replacements must match the 56 µH inductance, 3.99 Ohm DCR, and 4.90x11.35 mm form factor to ensure mechanical compatibility.
