Planar Common Mode Inductors

Mina Planar Common Mode Inductors are suited for use on the DC side of the inverter in photovoltaic systems and other DC systems. Solar inverters, that use MPP (maximum power point) trackers, generate noise ripple into both the grid's AC power line, as well as the DC side of the solar module. An AC filter is normally used on the grid's AC power line, but the noise generated on the DC side tends to be overlooked.
EMC standards EN 61000-6-3 and EN55014-1, however, also put limits on the noise generated from lines not connected to the grid, such as for example the line to the solar panels. Meeting these limits can be achieved by using a DC filter on the DC side of the inverter.

Common Mode Inductors range in inductance value from 1mH to 10 mH and current of 2 to 50 Amps models. They attenuate harmonics in the frequency range of 100 Hz to 100 MHz and it provides for very low value, low cost and high voltage Y capacitor that has low leakage current.

Pricing starts on Mina Inc, CMI at $5.00 each at 500 pieces.
