Increasing current densities and short switching times in MOSFETs are placing ever greater stress on the dielectric strength of inductors. Molded inductors with a distributed air gap based on iron powder enable high inductance values in the smallest of spaces and thus increase the power density. A new test con

Power factor is the ratio of the real power (P = Watts) to the apparent power (VA = Volt Ampere); the goal is to achieve a power factor as close to 1 as possible. A load with a lower power factor
