MODEL U25: This offers impedance (peak approximately 300 ohms @ 2 to 300 MHz) with negligible impedance below 1MHz. It will take a lead up to 12mm (1/2) diameter but preferably 10mm. Basically a split high permeability ferrite core with a plastic case, these devices are ideal where parasitic voltage spikes are a problem or potential problem. The cores come in a hinged plastic case, simply snap on to the computer or data cable.
Specifications:
- For cables: 10mm to 12mm (1/2") diameter
- Plastic case measures 32mm (L) x 30mm square.
