Note: for the proper operation of a 1:1 balun it is suggested an impedance of at least 500 Ohms (preferably 1000), this gives the possibility to obtain a good symmetrization of the coaxial cable on a balanced load.
Frequency range by application:
- EMI/RFI suppression: 25 - 300 MHz
- Inductive: <10 MHz
- Power magnetics: -
