Fixed Inductors Procurement Notes
Verify the End-of-Life status before procurement, as this component is scheduled for obsolescence. Confirm that the axial package and electrical parameters match the target circuit requirements. Ensure compliance with RoHS standards if required by the final assembly specifications.
Fixed Inductors Selection Notes
Select this inductor for applications requiring a 100 µH value with a 640 mA current rating. The axial form factor suits manual or wave soldering processes. Consider the 1.45 Ω DC resistance impact on efficiency. Verify availability due to the discontinued status of the product line.
Fixed Inductors Part Context
This part belongs to the B78108E series of leaded chokes and inductors. It shares the physical dimensions and core technology with other variants in the family but differs in inductance and current ratings. The series is designed for robust performance in industrial and automotive environments.
Fixed Inductors Replacement Considerations
The manufacturer has announced the discontinuation of this specific part number. Engineers should identify alternative components from the same series or compatible general-purpose inductors with matching 100 µH inductance, 640 mA current rating, and axial packaging.
