1537R-36G

Overview

The Delevan 1537R-36G is a fixed axial leaded RF inductor with an inductance of 10 µH and a tolerance of ±2%. It features a molded unshielded construction using an iron core. The component has a maximum DC resistance of 900 mΩ and a rated current of 335 mA. Key electrical characteristics include a minimum Q factor of 55 at 7.9 MHz and a self-resonant frequency of 45 MHz. It operates within a temperature range of -55°C to +105°C.

Feature Summary

• Molded unshielded coil design for RF applications
• Axial termination style for through-hole mounting
• Established reliability performance standards

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing circuits

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official datasheet to confirm exact tolerance and current ratings, as suffixes often denote critical variations. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets all required environmental and military specifications before finalizing the order.

Selection Notes

Select this component when a 10 µH inductance with tight ±2% tolerance is required for RF applications. Consider the 335 mA current rating and 900 mΩ DCR limits for power handling. The axial package and molded construction are suitable for standard PCB mounting where shielding is not mandated.

Part Context

This part belongs to the Delevan 1537R series of RF inductors. These components are characterized by their molded unshielded design and axial leads. The series supports various inductance values and tolerances, serving as passive components for signal integrity and filtering in electronic systems.

Replacement Considerations

The ER1537-36KR is a documented substitute within the same family, offering 10 µH inductance but with ±10% tolerance and a 290 mA rated current. Verify if the tighter tolerance and higher current of the 1537R-36G are critical for the application before substitution.
