1537R-36H

Overview

The Delevan 1537R-36H is a fixed axial leaded RF inductor from the 1537/R series. It features a molded unshielded construction with an iron core, designed for through-hole PCB mounting. The component provides an inductance of 10 µH with a tolerance of ±3%. It supports a maximum DC current of 335 mA and has a maximum DC resistance of 900 mOhms. Key electrical characteristics include a minimum Q factor of 55 at 2.5 MHz and a self-resonant frequency of 45 MHz. The unit operates within a temperature range of -55°C to +105°C.

Feature Summary

• Molded unshielded design utilizing an iron core for stable RF performance
• Axial leaded termination suitable for standard through-hole PCB mounting
• Established reliability construction for consistent inductive behavior

Applications

• RF circuit filtering and impedance matching
• Signal processing in communication equipment
• General-purpose radio frequency applications

Procurement Notes

Verify the specific suffix 'H' against official Delevan documentation to confirm the exact inductance value and tolerance class. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Cross-reference the RoHS status and REACH compliance details directly with the latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when a 10 µH inductance with tight ±3% tolerance is required for RF circuits. The unshielded molded design is appropriate where magnetic interference is not a primary constraint. Verify that the 335 mA current rating and 900 mOhm DCR meet the specific power handling needs of the target application circuit.

Part Context

This part belongs to the Delevan 1537/R series of RF inductors. The series offers various inductance values ranging from low microhenry to high tens of microhenry configurations. All variants share a standardized axial package size of 3.96 mm diameter by 9.53 mm length, ensuring mechanical compatibility across the product line.

Replacement Considerations

Direct substitutes within the same series include 1537R-30F (5.6 µH) or 1537R-42G (15 µH) if inductance adjustments are permissible. For equivalent 10 µH specifications, verify availability of other manufacturers' axial molded inductors with matching 335 mA ratings and similar self-resonant frequencies.
