This flat-wire, high-current inductor features a three-pad design engineered to deliver exceptional stability and board adhesion; its flat-wire winding structure ensures extremely low DC resistance. This product series offers a wide range of size specifications and inductance value options, making it suitable for use in POL, VRM, VRD, and various other high-power applications. In addition to possessing extremely low DC resistance, its inductance value exhibits an exceptionally slow rate of decline—even when current levels exceed the saturation current threshold. All raw materials meet RoHS and REACH regulations, and the product has a Moisture Sensitivity Level (MSL) rating of 1. Its maximum operating temperature is +125°c. Based on these features, this high-current inductor is ideal for harsh environments or various high-current power supply applications.
