Toroid FT-290-43 for broadband and EMI filters
Suitable for HF high power balun up to 1.5 kW.
Example application of a 1:1 balun in HF band.
| Frequency (MHz) |
Impedance (Ohm) |
1m RG400 or RG142 (6+6 turns) |
| 1.5 | 2000 | |
| 3.0 | 6000 | |
| 10 | 2500 | |
| 20 | 1100 | |
| 28 | 800 |
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
