high quality toroid


This ferrite toroidal core is used in our balun for our Yagi antennas.
It can also be used as a common mode choke or impedance transformer.

Technical Data:
AL(nH) 170 ±25%
Ae(cm2) 1.58
Σl/A(cm^-1) 9.2
le(cm) 14.5
Ve(cm3) 22.8

Dimensions:
Outer diameter: 61mm/2,4inch (tolerance +/- 1,3)
Inner diameter: 35,55mm / 1,4 inch (tolerance +/- 0,85)
Ring width: 12,7mm / 0,5 inch (tolerance +/- 0,5)

Information on the material:
Suitable for broadband common mode rejection in the frequency range from 7 to 200 MHz. With several cable windings around the toroidal core, the suppression increases while the frequency decreases. Typical applications are end-fed antenna impedance transformers, off-center fed antenna impedance transformers or 1:1 baluns as used in spider beams.
