Additional Details

The AME8818AEET250Z is a negative temperature coefficient (NTC) thermistor that acts as a resistance in series with the load. When power is applied, the thermistor starts at a high resistance, limiting the inrush current. As current flows through the thermistor, it heats up, causing its resistance to decrease. This allows the current to gradually increase to the normal operating level. The AME8818AEET250Z is designed to handle high surge currents and has a fast response time, ensuring effective protection against inrush current surges. It also has a low resistance in steady state, minimizing power losses and heat generation. Ametherm is a leading manufacturer of inrush current limiters, known for their high quality and reliability.

The AME8818AEET250Z is commonly used in switch-mode power supplies (SMPS) to protect the rectifier diodes and filter capacitors from damage caused by high inrush currents. It is also used in motor drives to limit the inrush current to the motor windings during startup. The AME8818AEET250Z is a reliable and cost-effective solution for inrush current protection in a wide range of electronic applications.
