105R-561K

Overview

The Delevan 105R-561K is a fixed surface-mount inductor with an inductance of 560 nH and a tolerance of ±10%. It supports a maximum DC current of 460 mA and has a maximum DC resistance of 450 mOhms. The component operates within a temperature range of -55°C to +105°C. Its physical dimensions are 2.5 mm by 2.5 mm, and it features non-standard two-lead termination.

Feature Summary

• Surface mount construction for automated PCB assembly
• Non-shielded magnetic design
• Fixed inductance value for circuit stability

Applications

• General purpose signal filtering
• Power supply input/output stages
• RF impedance matching networks

Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be sourced under various corporate identifiers. Confirm RoHS compliance status directly with the supplier documentation prior to integration. Ensure the non-standard lead configuration matches the target footprint design to prevent mechanical mounting errors during production.

Selection Notes

Select this component when a compact 560 nH inductance is required for low-current applications up to 460 mA. The unshielded nature necessitates careful layout planning to minimize electromagnetic interference coupling with adjacent traces. Verify that the 450 mOhm DC resistance aligns with the thermal management requirements of the specific power stage.

Part Context

This part belongs to the Delevan fixed inductor family, characterized by small form factors suitable for dense electronics. It serves as a passive energy storage element in electronic circuits. The product line emphasizes reliability in standard industrial and commercial environments through robust core materials and consistent manufacturing tolerances.

Replacement Considerations

Cross-reference with other 560 nH SMD inductors from manufacturers such as Coilcraft or Bourns. Ensure equivalent current ratings and physical dimensions are met. Verify that the replacement part maintains similar self-resonant frequency characteristics if high-frequency performance is critical.
