Saturable Cores for Mag Amps

Saturable cores for mag amps, a control mechanism for circular compression in switching power output. The miniaturization, high efficiency, low noise, high reliability, and high accuracy of the power supply can be realized by the mag-amp method, and it is especially suitable for low-voltage and high-current circuits. Our range includes the MT Series, which has outstanding saturability and low loss, and the highly versatile MS series.

Features

Outstanding saturability
Extremely low loss
Outstanding thermal behavior
