106-681G

Overview

The Delevan 106-681G is a fixed surface-mount inductor with an inductance of 680 nH. It features an unshielded construction and a maximum DC resistance of 600 mOhm. The component supports a current rating of 410 mA and operates within a temperature range of -55°C to 125°C. Its self-resonant frequency is specified at 160 MHz, tested at 25 MHz. The physical dimensions include a seated height of 1.90 mm.

Feature Summary

• Unshielded design for specific RF applications
• Surface mount technology for automated assembly
• Ferrite core construction for stable inductance

Applications

• RF circuit filtering
• General purpose inductive components
• Signal processing circuits

Procurement Notes

Verify the exact manufacturer designation, as API Delevan products are often listed under API Delevan Inc. Confirm RoHS compliance status and lead-free finish requirements against current datasheets. Ensure the unshielded package type matches the PCB layout constraints for the intended application.

Selection Notes

Select this component when a low-inductance value near 680 nH is required for high-frequency applications. The unshielded nature necessitates careful placement to avoid magnetic coupling with nearby traces. Verify that the 410 mA current rating meets the operational load requirements without excessive thermal rise.

Part Context

This part belongs to the Delevan fixed inductor family, designed for electronic filtering and signal conditioning. It represents a standard SMD solution for compact circuit designs requiring precise inductance values in the sub-microhenry range.

Replacement Considerations

Cross-reference with other 680 nH unshielded SMD inductors from manufacturers such as Coilcraft or Murata if supply is constrained. Ensure equivalent DC resistance and current ratings are maintained to preserve circuit performance.
