Within 31 x 24.9 mm footprint, PA4040 integrates common mode (CM) and differential mode (DM) choke into same component. This design, by reducing resistance, also reduces power losses across EMI filter portion of power supply. Along with 1,500 Vrms hi-pot and 3.0 mm creepage and clearance safety distance, choke features direct current resistance from 32–245 mΩ. Applications include any AC/DC or DC/AC power supply that uses DM and CM filter and where currents through filter are <3.5 Arms.
