Inrush Current Limiters (ICL) are among the widest used electronic components in today’s society. From industrial and commercial applications to residential uses, these simple yet powerful tools are rapidly becoming an essential part of many electronics projects.

One specific ICL that has been increasingly gaining traction is the SL12 17004 from Littelfuse. This device is a three-pin, AC-DC non-inductive NTC thermistor-based current limiting device that limits inrush current into power supplies for high-energy applications. Suitable for both DC and AC circuits, this device is capable of protecting against surges up to 100A.

The applications for this device are virtually limitless. The SL12 17004 is commonly used in industrial systems that require higher levels of load protection and surge suppression, such as data centers, telecom systems, medical equipment, and HVAC systems. This device can also be used in residential applications to provide power surge protection for domestic electrical systems.

The working principle of the SL12 17004 is also relatively straightforward. It is an AC-DC non-inductive NTC thermistor-based current limiting device that works by quickly responding to changes in the load current. When the current reaches a certain level, the thermistor circuit is activated, causing the temperatures to rise which, in turn, increases resistivity and lowers current flow. This method of limiting inrush current works by providing a consistent performance with minimal power loss and ensuring that over-currents and current surges are quickly dissipated.

In summary, the SL12 17004 from Littelfuse is a powerful and efficient Inrush Current Limiter that can be used in a broad range of applications. Able to limit inrush current up to 100A and protect against surges, this device is the perfect solution for industrial and residential projects and can provide reliable and consistent performance.
