Inrush current is a common problem in almost all applications of electricity, due to the large currents that can be drawn at start-up or initial powering of an electrical device, that result from the sudden connection of energy storage components to the power supply. Inrush current limiters (ICLs) are designed to protect the device and the power supply from excessive inrush current.

The NF20AA0150M is a type of inrush current limiter that works by relying on a solid-state thermal element to control the amount of current that can be drawn when the device is first powered. This device consists of a thermally conductive path and two resistors, one which is the inrush limit resistor, and the other which is the regulated output resistor. This path has a temperature coefficient of resistance which is dependent on the temperature; when a large inrush current is initially drawn, the temperature of the thermally conductive path rises, increasing the resistance of the path. As the temperature of the path rises due to heat generated due to inrush, the resistors in the path reduce the current that can be drawn from the power supply, providing protection from excessive inrush current.

The NF20AA0150M can be used in a variety of applications, including powering up computers, medical devices, servers and other computing equipment, programmable logic controllers, industrial automation systems, electric motors, and power supplies. Additionally, it is often used for automotive applications, such as powering up vehicle electronics, or as an ALDL connector that connects the vehicles onboard diagnostics systems.

This type of inrush current limiter is a single module device and is relatively simple to install; it can be easily connected to the power supply and the electrical device, and requires no additional components. Once the connection is made, the NF20AA0150M will protect the device or system from any excessive inrush current. This device is available in various temperature ratings from 100 to 300 degrees Celsius, allowing for greater flexibility in application.

The NF20AA0150M inrush current limiter is a reliable and cost effective solution for protecting electrical systems from the damaging effects of excessive inrush current. It is ideal for use in a variety of applications where power needs to be initially supplied, as it provides the necessary protection from high starting currents while allowing for a dependable, economical supply of power.
