Würth Elektronik eiSos has designed these new common mode chokes for network applications with alternating voltages of up to 760V. Aside from the power electronics application area, the WE-CMB HV series is also designed for use in input and output filters and for motor interference suppression.
The threefold higher rated voltage offered by the WE-CMB HV products, compared with the regular series of power line chokes, was made possible by doubling the clearance and creepage distances.
A new plastic casing and an improved separating strip enable an insulation voltage of 3,000VAC to be achieved. All insulation materials used in these products are UL94-V0 listed.
The new series is compatible with the grid designs of the existing WE-CMB and WE-CMB-NC series. The WE-CMB HV design is available in the versions XL and XXL.
Free samples are available upon request; all power line choke products are directly available from stock.
