Overview
The Delevan 105-682K is a fixed surface-mount inductor from the Micro i Chip series, designed for RF applications. It features an unshielded construction with a ferrite core and offers a nominal inductance of 6.8 µH with a ±10% tolerance. The component supports a maximum DC current of 160 mA and has a maximum DC resistance of 3.8 Ohms. It utilizes standard SMD terminations and operates within a temperature range of -55°C to 125°C.
Feature Summary
- Unshielded micro chip inductor design suitable for RF signal processing
- Ferrite core construction providing stable inductance characteristics
- Surface mount termination style for automated PCB assembly
Applications
- RF circuit filtering and impedance matching
- General purpose signal conditioning in electronic systems
- High-frequency choke applications in communication devices
Procurement Notes
Verify RoHS compliance status as documentation indicates potential variations. Confirm availability through authorized distributors, noting that some sources may list restricted supply or end-of-life notifications. Ensure the specific batch matches the required ±10% tolerance and 160 mA rating for your design.
Selection Notes
Select this component when an unshielded 6.8 µH inductor is required for RF environments. Consider the 3.8 Ohm DCR limit for power loss calculations. The 160 mA current rating dictates suitability for low-power signal paths rather than high-current power stages. Verify package dimensions against board space constraints.
Part Context
This part belongs to the Delevan Micro i Chip series, which provides compact fixed inductors for surface mount technology. The series includes various inductance values tailored for general-purpose and RF applications, utilizing ferrite cores to maintain performance across wide temperature ranges.
Replacement Considerations
Public confirmed substitutes include the 105-682GS (noting it is EOL) and the 1331-682K. Note that the 1331-682K is shielded and has different physical dimensions, requiring mechanical verification before substitution.
