The RN212-1.2-02 is a 1.2A current-compensated EMC/EMI Choke has high saturation resistance and excellent thermal behaviour. Symmetrical component of the noise is also attenuated by the leakage inductance of the windings. This choke is typically used in conjunction with suppression capacitors. It is suitable for EMI input filters, suppressing equipment with no earth connection and suppressing high interference levels.
