Figure 4. Reactive Termination Application Circuit Schematic
¹This design was tested and found to comply with FCC Part 68 with this
Sidactor. Other compliance requirements may require a different part.
²Higher-noise power supplies may require substitution of a 220 μH inductor,
Toko 380HB-2215 or similar. See the Power Quality section of Clare
application note AN-146,
more information.
