Inrush current limiters (ICLs) have become an essential component in virtually all electronic devices that require stable power. One of the more popular ICLs on the market today is the SL22 7R010. This ICL comes with several unique features including its fast response time, its ability to withstand high temperatures, and its small size. In this article, we will take a look at the SL22 7R010\'s application field and working principle.

The SL22 7R010 ICL is designed to offer fast response and reliable operation in a variety of applications. Since it has a fast response time, it is able to quickly limit the inrush current to protect the circuits from damaging bursts of electricity. This makes it perfect for applications ranging from power electronics to automotive systems. Additionally, this ICL can operate in temperatures up to 125° C, making it ideal for high temperature environments such as telecommunications and industrial equipment. Lastly, this ICL is small in size, making it easy to package in a wide range of spaces.

The SL22 7R010 ICL works by allowing a short-term high inrush of current but then quickly limiting it to a predetermined value. It does this by using a pair of thermistors that are configured in a series configuration. One of the thermistors has a high positive coefficient and the other has a low negative coefficient. When the ICL is powered up, the two thermistors create a voltage divider circuit. This creates a current shunt, allowing the high inrush current to enter the circuit while keeping the rest of the system safe.

Once the inrush current reaches the predetermined value, the thermistors stop the current from flowing any further. Since the thermistors have a high positive coefficient, they maintain their resistance even at high temperatures. This allows them to continue limiting the inrush current even in extreme conditions. By stopping the current at the predetermined level, the SL22 7R010 ICL provides reliable power to the system while protecting against damaging spikes.

The SL22 7R010 ICL is a versatile device that can be used in a variety of applications. From power electronics to automotive systems, this ICL can provide reliable and stable power for a wide range of uses. Its fast response time, high temperature endurance, and compact size make it a great choice for many projects. While there are many types of inrush current limiters available on the market, the SL22 7R010 is one of the best options for delivering reliable performance.
