HF version for high data rates

While the WE-CNSW series can work up to USB 2.0 interfaces, the WE-CNSW HF was designed to have wider frequency band to be able to work with the newest high-speed interfaces.

WE-CNSW HF Series

Fully automated production

Thanks to the fully automated process, a high degree of winding symmetry and constantly high quality can be achieved. The winding symmetry ensures low parasitic effects and therefore high signal integrity.

Common and Differential Mode Behavior

When the common mode component of a signal tries to pass through the choke, it encounters a high impedance. This is caused by the magnetization of the core and the resulting mutual inductance in the coil.

In contrast to the common mode behavior, the differential mode signal will see almost no impedance, which can be explained by the magnetic field compensation in the core. If the core is not magnetized, there is no mutual inductance so that the useful signal can pass through.

Temperature Derating

How to interpret the temperature derating curve?

Check the data sheets for operating temperature. All derating curves for our CMC can be found in REDEXPERT.

T_R = Rated Temperature
T_max = Upper limit of the operating temperature and max. temperature allowed
ΔT = T_max – T_R

Example of use:
The maximum abient temperature with maximum current capability is 85 °C over this temperature the current capabilities sink. For a higher ambient temperature the maximum current can be read easily from the derating curve with the help of the chart marker.

Bifilar vs. Sectional Winding

Bifilar winding shows the lowest attenuation in differential mode. These chokes are recommended for data lines, where a high isolation is not needed and some high speed signals are involved.

Sectional winding shows the highest attenuation in differential mode. This chokes are recommended for power lines, where a high isolation is mandatory, and the power delivery is happening at low frequency.
