Ideal for noise removal in switching power supplies and AC lines! Compact and high-impedance EMI countermeasure coil.
The Coilcraft P32xx series toroidal common mode chokes are ideal noise filters for power circuit design, such as switching power supplies and AC line filters. With a toroidal core structure and single-layer winding design, they effectively suppress high-frequency noise in the 100-300 kHz range. They powerfully eliminate common mode noise and power supply noise generated on power lines. The lineup includes the "High L series" with high inductance design and the "Standard series" with low DCR and high current capability, allowing you to choose the optimal model for your application. Additionally, with a high-reliability design certified by UL (Class B 130°C) and compliant with RoHS/REACH, they can be safely used in various fields such as industrial equipment power supplies, communication devices, home appliances, and PoE devices. Despite their small size, they demonstrate excellent EMI countermeasure performance and enhance the design flexibility of filter circuits, enabling robust circuit design against noise.
