108R-153H

Overview

The Delevan 108R-153H is a fixed inductor with an inductance of 15 µH and a tolerance of ±3%. It features a maximum DC current rating of 79 mA and a maximum DC resistance of 4.2 Ohms. The component has a self-resonant frequency of 24 MHz and is designed as an unshielded unit. It utilizes a nonstandard, two-lead surface mount package with a maximum seated height of 0.075 inches (1.91 mm).

Feature Summary

• Unshielded magnetic design for specific RF applications.
• Nonstandard two-lead surface mount configuration.
• High self-resonant frequency capability.

Applications

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

Procurement Notes

Verify the exact physical dimensions against the official datasheet due to the nonstandard lead configuration. Confirm that the 79 mA current rating meets the thermal requirements of the target application. Ensure the unshielded nature does not cause interference in dense layouts. Check RoHS compliance status before finalizing procurement.

Selection Notes

Select this component when a 15 µH inductance with low current handling is required for RF frequencies. The unshielded construction may necessitate careful placement to avoid coupling. Compare the 4.2 Ohm DC resistance against circuit loss budgets. Consider the nonstandard footprint during PCB layout generation to ensure proper soldering.

Part Context

This part belongs to the Delevan fixed inductor family, characterized by axial or specialized lead styles rather than standard SMD packages. It serves niche RF roles where specific form factors are needed. The 108R series typically offers stable performance at radio frequencies with moderate current limits.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify mechanical fitment if considering alternative manufacturers.
