1537R-72H

Overview

The Delevan 1537R-72H is a fixed axial leaded inductor featuring an unshielded molded coil design. It provides an inductance of 82 µH with a tolerance of ±3%. The component supports a maximum DC current of 162 mA and exhibits a maximum DC resistance of 3.9 Ohms. Constructed for through-hole mounting, this part is suitable for RF applications requiring compact, reliable inductive elements without magnetic shielding interference.

Feature Summary

• Unshielded molded coil construction prevents magnetic interference with nearby components
• Axial leaded configuration facilitates standard through-hole PCB mounting
• Fixed inductance value ensures stable circuit performance in RF environments

Applications

• RF signal filtering circuits
• Impedance matching networks
• General purpose electronic equipment requiring small form factor inductors

Procurement Notes

Verify the specific manufacturer source, as API Delevan assets have transitioned to other entities. Confirm RoHS compliance status and exact tolerance grades (±3%) against current official datasheets from authorized distributors. Ensure the axial package dimensions match your board layout requirements before finalizing orders.

Selection Notes

Select this component when an unshielded inductor is required to avoid magnetic coupling issues in dense layouts. The 162 mA current rating dictates suitability for low-power RF stages rather than high-current power supplies. Verify that the 3.9 Ohm DC resistance aligns with the circuit's voltage drop constraints.

Part Context

This part belongs to the Delevan 1537R series of fixed RF inductors. These components are characterized by their molded epoxy construction and axial leads, distinguishing them from shielded or surface-mount alternatives. The series offers various inductance values tailored for radio frequency and communication hardware.

Replacement Considerations

Cross-reference with other axial molded inductors offering 82 µH ±3% tolerance and similar current ratings. Ensure replacement parts maintain the same physical footprint and electrical characteristics, specifically the 3.9 Ohm maximum DC resistance.
