Round cable ferrite bead
Common applications:
- Impedance matching
In power HF transformers on the output of MOS-FET or bipolar transistors, the maximum power is estimated at about 200/400W, see application example - Choke and EMI filter up to 500 MHz
Typical impedance
Frequency 1 turn 3 turns 10 MHz 105Ω 900Ω 25 MHz 171Ω 1539Ω 100 MHz 250Ω 650Ω 250 MHz 255Ω 250Ω - Common mode rejection choke on coaxial cables
When on the screen of a coaxial cable there is a RF current it is necessary to include a common mode choke, this situation often happens when you change from an unbalanced impedance to a balanced one (coaxial cable on balanced dipole antenna). This ferrite is compatible with all coaxial cables up to 6mm diameter including RG58, RG223, RG142, etc..., for this application it is recommended a choke impedance of at least 10 times higher than that of the coaxial cable
Example of application on coaxial cable
Test conditions: 1m RG58, 35x TF-98
1200Ω @ 1.8 MHz
2600Ω @ 3 MHz
2000Ω @ 10 MHz
900Ω @ 21 MHz
700Ω @ 30 MHz
