Inrush Current Limiters (ICL) are devices that limit the peak current for fast-transient power sources, such as power supplies or line filters. The SL22 30005-T is one such device, employed to control the inrush current for various system applications.

Overview

The SL22 30005-T is a robust, modern, and cost-effective ICL that has been designed by Sumida using a high-efficiency NTC negative temperature coefficient resistor. It is constructed in a single, easy-to-install package that requires no additional external components to operate. The SL22 30005-T features an integrated thermistor that can withstand high inrush currents, and a built-in thermal cut-off device which acts as an overload and over voltage protection system for the resistor. The device is rated for a maximum voltage of 50 volts and is available in various packages and sizes depending on the application.

Application Fields

The SL22 30005-T is most often used in the power management fields, for applications such as power supplies, line filters and motor controls. It is also used in telecommunications, computing and consumer electronic industries, where it is employed to limit the inrush current, which could otherwise damage the equipment or cause an overload of the power system. This device is suitable for applications where high temperature and wide variation in the input voltage are encountered, and it can be used with a variety of AC or DC input voltages due to its wide operating range.

Working Principle

The SL22 30005-T works by limiting the peak magnitude of the inrush current to a predetermined value that is determined by the device\'s specifications. The current is limited by the NTC thermistor, which has a negative temperature coefficient, meaning that the resistance of the thermistor decreases as the temperature increases. As the temperature rises, the thermistor\'s resistance is lowered, allowing more current to pass through it. The thermistor can be connected to a fixed resistor and capacitor network that acts as a ripple filter, which helps to reduce the noise and ripple in the power system. The thermal cut-off device provides additional protection for the thermistor, as it will shut off the power to the thermistor if it detects any over-current or over-voltage.

Conclusion

The SL22 30005-T is a robust, modern, and cost-effective ICL that limits the peak current for fast-transient power sources. It is most often used in power management fields, and supported by a wide operating range that facilitates usage of a variety of AC or DC input voltages. The device also features an integrated thermistor and a thermal cut-off device, providing maximum safety and protection against overloads and over-voltages.
