Inrush Current Limiters (ICLs) are components designed to prevent large inrush currents during power up or power switching of applications. The NTPA5220LB1A0 is a type of ICL that is used in a wide variety of applications across a broad range of industries and works by limiting the amount of current that can be drawn when energizing power to a load.

The NTPA5220LB1A0 is a dual channel inrush current limiter and is the most compact in its class. It offers a solution for current-controlled inrush applications up to 5A, while at the same time offering cost, size, and energy savings. Due to its small size, this component can be used in very small and complex PCB designs and assemblies and is suitable for multiple levels of current control.

The working principle of the NTPA5220LB1A0 is based on a thermal-laminar process. When the limiter receives power from the power supply, it creates a thin sheet of copper-like material which acts as a resistor to limit current flow to the load. It is then heated and cooled rapidly to maintain a predetermined, consistent temperature for the duration of the operation. This process allows for a steady current flow to the load yet with a maximum threshold current.

This ICL can be used in several different applications such as speaker protection, dimmer control, and lighting control, among many others. It can also be used in professional and industrial applications such as factory automation, robotics, and medical equipment. It is also suitable for automotive uses such as fuel injectors and start/stop systems.

In the medical industry, the NTPA5220LB1A0 Limiter is used to limit current to medical devices such as oxygen concentrators, ventilators, and other equipment needing protective current limits. Its ability to be used in extremely compact designs make it ideal for such applications.

The NTPA5220LB1A0 is also used in conjunction with power controllers in automotive applications. It limits current to the power controller so that it can safely switch between power inputs while maintaining stability of the power system.

Aside from its numerous uses, benefits such as energy saving, reduced standby power, and high accuracy make the NTPA5220LB1A0 an ideal ICL for many applications. It is designed to meet RoHS and UL safety regulations and is fully certified for a variety of global markets. With its broad application field and excellent performance, the NTPA5220LB1A0 is the only choice for high-current, multi-level inrush current control.
