Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system, particularly sags that trip loads.

Digi-Key, in collaboration with Ametherm, presents a PTM describing transformer protection from inrush current using the NTC thermistor. This will provide a problem statement describing the inrush ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

However much care is taken, it is very difficult to keep all traces of transformer-induced hum out of the signal circuitry. It is highly irritating to find that despite the cunning use of low-noise ...

TDK-EPC has extended its range of EPCOS inrush current limiters (ICL). The P11 series (B57211P*) covers a resistance range from 4 to 25 ohms (R25). TDK-EPC has extended its range of EPCOS inrush ...

MALVERN, Pa., Oct. 22, 2025 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of insulated, surface-mount inrush current limiting positive temperature ...

Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...
