1537R-90F

Overview

The Delevan 1537R-90F is a fixed axial leaded RF inductor from the 1537R series. It features a molded unshielded construction with an iron core. Key electrical parameters include an inductance of 200 µH, a maximum DC resistance of 7.1 Ohms, and a rated current of 120 mA. The component operates within a temperature range of -55°C to +105°C.

Feature Summary

• Molded unshielded design for RF applications
• Axial leaded termination for through-hole mounting
• Iron core construction

Applications

• RF circuits
• Through-hole PCB mounting

Procurement Notes

Verify the manufacturer designation, as API Delevan assets are often associated with Cooper Industries or similar entities. Confirm RoHS compliance status and specific packaging quantities directly with authorized distributors. Ensure the part number matches the exact 200 µH specification to avoid confusion with other values in the 1537R series.

Selection Notes

Select this component for applications requiring high inductance in a compact axial form factor. Consider the 120 mA current rating and 7.1 Ohm DC resistance when designing power stages. Verify that the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field emission.

Part Context

This part belongs to the Delevan 1537R series of fixed inductors. These components are characterized by their molded epoxy construction and axial leads, designed specifically for radio frequency and general-purpose electronic circuits requiring reliable through-hole integration.
