Inrush Current Limiters (ICL): SG170 Application Field and Working Principle

Inrush current limiters, also known as ICLs, are safety components that are designed to protect sensitive and expensive equipment from surge currents, damaging electrical surges and overvoltage conditions. By limiting the amount of current that can flow into electronic equipment, ICLs help to ensure that the equipment is working properly and efficiently. In this article, we will discuss the SG170 ICL\'s application field and working principle.The SG170 is an inrush current limiting device manufactured by KEMET Electronics, a leading supplier of electronic components and industrial equipment. The product is designed to protect components, printed circuit boards (PCBs), and equipment from overvoltage conditions and electrical surges. It has a slim design that makes it suitable for low profile applications where space is a major concern. It is rated for a maximum current of 25A with a minimum current of 3A.The SG170 is used primarily in switching-mode power supply (SMPS) applications. It is also used in power supply circuits such as LED lighting systems, aquariums, surge protectors, security systems, and chargers. It is particularly suitable for use in applications where high currents can be expected such as computers, laser systems, and broadcasting equipment. The SG170 has a wide operating temperature range of -40°C to +125°C, making it suitable for use in a variety of environments. It is designed with an ultra-low leakage rate in order to minimize self-heating. It is available in a range of packaging options including through-hole, surface mount, and pre-wired versions. The working principle of the SG170 ICL is to limit inrush currents during power up and down cycles. It consists of a passive Linear Ramping™ circuit that starts to reduce the current through the device as the voltage begins to rise. The current reduction is controlled as a linear ramp, and can be adjusted through an external resistor. When power is applied to the system, the SG170 performs its current limiting function and reduces inrush current at a low rate (but fast enough to protect the components). It does this by steadily reducing the voltage, allowing the current to ramp up slowly. When the voltage reaches a predetermined level, the SG170 is switched off and the nominal operating current is established. The SG170 also offers protection against overvoltage and reverse current protection. As the voltage level increases, the SG170 detects the overvoltage and switches off. It then reduces the current again until the voltage level stabilizes. When the voltage decreases, the SG170 will detect the reverse current and again switch off.The SG170 inrush current limiter is a reliable and cost-effective solution that can be used in any application where inrush currents need to be limited. Its adjustable functions make it suitable for devices with different power requirements and ratings. It is also a highly reliable component that offers good protection against electrical surges and overvoltage conditions.
