The PWH4012-2R2M1T is designed for modern synchronous buck converters that demand very low loss and strong saturation margin. The metal-composite core enables high ripple current operation with controlled inductance roll-off, supporting stable transient behavior during fast load steps. Molded shielding minimizes stray fields, improving EMI performance and layout flexibility. This part is well suited for compact VRM/POL stages, high current battery-powered systems, telecom boards, and industrial embedded computing platforms requiring maximum performance in 1.2mm height.
