Inrush Current Limiters (ICL) are electronic components, often used in applications where the initial inrush current is too high or the load current should be controlled or limited. They prevent the initial high current surge or overload currents from damaging the components in the circuit. SL12 80002 is one of the most common ICLs used in many electronic applications. In this article, we’ll discuss the application field and working principle of SL12 80002.

SL12 80002 is a miniature inrush current limiter, designed to protect sensitive components from inrush current in many electronic control instruments, power supplies, transformers, motors, and solenoids. It provides protection both in terms of thermal and electrical overloads. The device has a small package size (7.5X5.0 mm) with shielding, and a low profile, making it extremely useful in small, compact applications. The device has thermal insulation in both directions, low inductance and a fast response time, which makes it suitable for high-frequency applications.

SL12 80002 has a wide operating parameter range, allowing it to be used in different application circuits. It\'s rated for an operating voltage up to 160V and a peak pulse current up to 3A, with a wide temperature range of -55°C to +85°C and high thermal and electrical stability. The device also has an internal soft-start function which helps minimize inrush inrush currents and limit it to a preset level.

The working principle of SL12 80002 is quite simple. When the power supply is switched ON, an inrush current (or overload current) occurs. The device detects this increase in the current and restricts it to a predetermined level. When the current reaches the limit, the device limits the current to a certain level by using two resistors in series connected in the path. This result in preventing any excessive current from flowing through the circuit elements.

The SL12 80002 is an easy to operate and cost-effective ICL with low on-state output capacitance and low resistance for applications requiring fast inrush current limiting. It\'s a reliable device that can handle high currents efficiently over a wide temperature range. Its small size and ability to withstand high pulse currents makes it an ideal choice for applications in harsh environments. It can also be used in various switchgear systems to control the inrush current.

In conclusion, SL12 80002 is one of the most popular Inrush Current Limiters, used in many different applications. It offers protection against high inrush current, overload currents and thermal overloads, and provides efficient control over the current limiting process. This makes it an ideal device for all kinds of electric and electronic applications.
