High Current 3R3 Flat Wire SMD Inductors Manufacturing
This flat-wire high-current inductor features a three-pad design for superior stability and board adhesion; its flat-wire winding structure ensures extremely low DC resistance. This product series offers a wide range of sizes and inductance options, suitable for POL, VRM, VRD, and other high-power applications. All raw materials comply with RoHS and REACH regulations, and the product has a humidity sensitivity rating (MSL) of 1. In addition to extremely low DC resistance, its inductance exhibits minimal decay even when the current exceeds the saturation current threshold. Its maximum operating temperature reaches +125°c. With these characteristics, this high-current inductor is ideal for harsh environments or high-current power supply applications.
We can also provide custom-designed high-current flat-wire inductors. For any inquiries, please contact us at info@smdinductor.com. Zhenhua Company provides inventory information, product quotations, and technical specifications for flat-wire inductors and offers wholesale pricing services.
