1537R-38G

Overview

The Delevan 1537R-38G is a fixed axial leaded inductor designed for radio frequency applications. It features an unshielded molded coil construction with a nominal inductance of 12 µH and a tolerance of ±10%. The component supports a maximum DC current of 305 mA and exhibits a maximum DC resistance of 1.1 Ohms. This through-hole device utilizes an axial package configuration suitable for standard PCB mounting techniques.

Feature Summary

• Unshielded molded coil construction for RF applications
• Axial leaded package for through-hole mounting
• Fixed inductance value with standard tolerance

Applications

• Radio frequency circuit filtering
• General purpose inductive components in electronic assemblies
• Signal processing circuits requiring fixed inductance

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often associated with Cooper Industries or similar entities depending on the production era. Confirm RoHS compliance status directly with the supplier, as historical data indicates varying environmental compliance levels for this series. Ensure the axial lead form factor matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 12 µH inductance with low current handling is required in an unshielded format. The axial lead style facilitates easy insertion into legacy or high-reliability through-hole designs. Consider the 1.1 Ohm DC resistance impact on circuit efficiency and ensure the 305 mA current rating exceeds the maximum expected operating current to prevent saturation or overheating.

Part Context

The 1537R series represents a line of fixed RF inductors characterized by their molded, unshielded design. These components are typically used in applications where magnetic shielding is not critical or where size constraints favor a compact axial form factor. The series offers various inductance values, with the 1537R-38G specifically providing 12 µH performance.

Replacement Considerations

Direct substitutes include other 12 µH axial unshielded inductors from manufacturers such as Coilcraft or Bourns, provided they match the 305 mA current rating and 1.1 Ohm resistance limits. Verify that any replacement maintains the same physical axial dimensions and lead spacing to ensure mechanical compatibility without PCB modification.
