* Toroids are tested for AL values at 10KHz.
43 Material – specifications:
|Flux density @ field strength||B|
|Residual flux density||Br||1300||Gauss
|Loss factor @ specific freq.||Tan δ/ µi||250|
|Temperature coefficient of initial permeability (20 -70°C)||1.25||%/°C
Usable frequency ranges, depending on the application:
broadband transformers: 5 – 400 MHz
power transformers: 0.5 – 30 MHz
RFI / EMI / CMC suppression: 5 – 500 MHz
✔️ common mode chokes (CMC): material 43 it is a very good solution for suppressing common broadband currents in the range of 10 – 600 MHz. Along with the increase no. of turns, the suppression increases, while the max. usable freq. will decrease.
✔️ broadband transformers: excellent impedance transformers can be made in the frequency range from 2 to 50 MHz Typical applications are impedance transformers for EndFed antennas, impedance transformers for OCFD antennas or BalUn 1: 1.
