Two Line DC Filter Range
Two line DC power line filters feature a combination of feedthrough capacitors with high permeability toroidal current compensating inductors for high performance filtering in a small rectangular case, designed for mounting on a bulkhead. To achieve the full benefits of this design, it is important that the load current returns through the filter. They are suitable for voltages up to 250VDC.
Insertion Loss Performance
Asymmetric attenuation shown as measured in 50Ω system, at all loading conditions, in accordance with CISPR-17.
Performance curve meets 100dB from 10kHz to 10GHz.
