6 windings together and 8 windings
distributed over the core
Windings distributed over the core
Schematic:
First measurement:
Windings distributed over the core without and with compensation capacitor.
Windings distributed over the core without compensation capacitor.
Second measurement:
Windings distributed over the core with compensation capacitor.
Third measurement:
Windings toghether on the core with compensation capacitor.

Insertion Loss measurements:
Reference measurement to determine loss ft240-43 cores.
Insertion Loss measurements with the FT400-43 core:
Result of the FT400-43 core:
@ 1.8 MHz: 1.6 dB = 31 % loss (310 W @ 1 KW)
@ 3.6 MHz: 1.2 dB = 24 % loss (240 W @ 1 KW)
@ 7.2 MHz: 0.9 dB = 19 % loss (190 W @ 1 KW)
@ 14.1 MHz: 0.9 dB = 19 % loss (190 W @ 1 KW)
@ 21.3 MHz: 1.3 dB = 25 % loss (250 W @ 1 KW)
