A molded inductor (such as the WHYT/WHYTA/WHYTP series) is a power inductor made by embedding the coil in metal magnetic powder and compression-molding it into a single body. Compared with traditional assembled wire-wound inductors, it has an integrated structure and a closed magnetic path, offering small size, good magnetic shielding, low flux leakage, vibration resistance, and low noise - particularly suitable for high-density board-level power supply designs.
They are widely used as energy-storage and filter inductors in DC-DC buck/boost circuits, commonly found in CPU/GPU power delivery (VRM), servers, laptops, automotive electronics, and power modules - applications involving high current, high-frequency switching, and tight space constraints.
Molded inductors use metal powder cores with a distributed air gap, so the inductance decreases slowly and smoothly as current increases (soft saturation), whereas gapped ferrite inductors show a sharp inductance drop at the saturation point (hard saturation). Soft saturation means the inductance will not suddenly collapse during momentary overcurrent (such as load transients or startup inrush), keeping the current ripple under control and the system safer, and allowing parts to be selected closer to their saturation current.
