105R-182H

Overview

The Delevan 105R-182H is a fixed surface-mount inductor with an inductance of 1.8 µH and a tolerance of ±3%. It features a maximum DC current rating of 250 mA and a maximum DC resistance of 1.5 Ohms. The component utilizes a nonstandard two-lead SMD package design, distinguishing it from standard quad-terminal devices. This unshielded configuration is intended for compact circuit board layouts where space constraints are critical.

Feature Summary

• Unshielded magnetic structure suitable for applications where shielding is not required or external shielding is managed by the system design.

Applications

• Compact power supply filtering circuits
• Signal processing stages requiring low-current inductance
• Space-constrained PCB designs

Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be listed under API Delevan Inc. Confirm the lead style matches the nonstandard two-lead specification rather than standard four-terminal SMD packages. Ensure the 250 mA current rating meets the application requirements before integration.

Selection Notes

Select this component when a small footprint is prioritized over high current handling. The 1.5 Ohm DC resistance limits its use to low-power signal paths or filters. Compare against shielded alternatives if electromagnetic interference suppression is necessary for the target circuit.

Part Context

This part belongs to the Delevan fixed inductor family, characterized by compact SMD form factors. Unlike the SP1210R series which offers higher current ratings and shielding, the 105R series focuses on minimal size for lower current applications.

Replacement Considerations

The 105R-182F is a documented variant with identical electrical specifications but potentially different tolerance or packaging suffixes. Verify mechanical compatibility before substitution.
