Inrush Current Limiters (ICLs) help prevent damage to electronic equipment by limiting the amount of current that can flow into the component when power is first applied. SL22 0R712 is a series of ICLs (inrush current limiters) from Vishay and is employed in numerous fields, especially in DC/DC converter components and LED driver applications. This article will discuss the SL22 0R712 application field, working principle and characteristics in detail.

Application Field of SL22 0R712

SL22 0R712 has a wide range of application fields. It is commonly used in LED lighting driver applications to reduce the risk of fire, damage, and/or malfunction. It is especially suitable in a variety of LED lighting applications due to its ultra-low resistance characteristics and improved power routing due to its small form factor. Furthermore, SL22 0R712 also finds use in DC/DC converter components, avoiding the problems that occur when capacitors of high energy storage are connected to the circuit, such as high inrush currents or destructive voltage spikes. Thus, SL22 0R712 can offer safety, protection and performance in both AC/DC and DC/DC converter circuits.

Working Principle of SL22 0R712

The SL22 0R712 is an NTC-type inrush current limiter, composed of two elements in parallel - one Thermistor plus one Resistor. It\'s typically used to limit the inrush current at switch on of any power source in an electronic controller circuit. SL22 0R712 acts as a resistor when a power source is turned on, allowing only a limited amount of current to flow into the circuit, hence avoiding inrush current and surges that can cause damage to the components. When the power source is turned off, the series increases its resistance so that the current flow stops.

The inrush current rating (the amount of current that can be safely allowed to pass through the device) is determined by the NTC-type thermistor body size, and the series resistor size. By using these two components, SL22 0R712 is able to reduce inrush current surges to any electronic controller circuit, while operating in the safe temperature range. Due to its superior current limiting characteristics at low power levels, SL22 0R712I is highly recommended for LED lighting driver applications.

Characteristics of SL22 0R712

SL22 0R712 is available in small-sized designs, which makes it ideal for a wide range of applications. Due to its small size and low overall resistance, it is able to provide superior current limiting characteristics at low power levels. Also, it is able to support up to a 50A inrush current, which is much higher than traditional inrush current limiters. In addition, its operating temperature ranges from -40°C to 125°C, making it suitable for use in various environmental conditions. Finally, SL22 0R712 also offer excellent noise and ripple rejection, making them ideal for noise-sensitive applications.

In conclusion, SL22 0R712 is an excellent inrush current limiter that is suitable for use in LED lighting applications and DC/DC converter components. It is able to reduce inrushcurrent surges to any electronic controller circuit, while operating in the safe temperature range. Due to its small size, low resistance, and excellent current limiting characteristics, SL22 0R712is a highly valuable component for use in power circuit designs.
