Wurth Elektronik Openable Ferrite Sleeve with key, 35 x 31.5 x 28.3mm, For Bluetooth, LAN Network, Wireless Lan,

With air gap of 0.8 mm
Split case ferrite with "defined air-gap" (patented)
Especially helpful for EMI problems in frequency range of 100 MHz up to 1.0 GHz
Data signals up to 100 MHz will not be effected
Best performance (impedance) especially with 2 windings
Low magnetic saturation of the material in cases of high DC current applications which therefore gives a low reduction of impedance
Pre-fixing cable system facilitates the assembly process
Cable clamping protection
Internal security locking system with patented key technology (STAR-TEC key) prevents unauthorized removing from the cable
One key in each packaging unit
Plastic housing
Operating temperature: –25 °C to +105 °C
Core material: NiZn
Applications
High speed data lines, especially LAN network CAT5 and higher
Less influence for your electronic by wireless mobile phone radiations, bluetooth and wireless LAN
Reduce disturbance by USB 2.0 and other fast digital signals
Minimize the interference by fast circuits and SMPS
Suppression of the harmonic waves and no damping for the signal below 100 MHz
Better performance for high DC current applications with interference problems like power supply, motor drives and more
