Introduction to Inrush Current Limiters (ICL)

Inrush current limiters, or ICLs, are a type of electronic component widely used to control and/or limit the large amounts of current that components draw when powered up. This helps protect the circuit from overload, overcurrent, or short-circuiting. The SL08 7R002 in particular, is one of many ICLs designed to help prevent the large inrush of current that might occur during the startup of an electric circuit.

How it Works

The SL08 7R002 works by introducing a variable impedance into the circuit at startup, which helps reduce the peak inrush current. This is done through the use of a thermistor, an electronic component that changes its resistance with a change in temperature. When the power is initially applied to the circuit, the thermistor is cold. Thus, it has a high resistance, restricting the amount of current that is allowed to pass. This causes the current passing into the circuit to slowly rise over time, preventing any sudden spikes in current. This, in turn, prevents the circuit from being damaged by the large inrush of current. As the thermistor warms up, its resistance value begins to decrease, allowing more current to pass. Eventually, the unit will reach a steady-state level, where the current passing through the thermistor is equal to the current passing through the circuit. This helps ensure that the current going into the circuit remains constant, preventing any sudden spikes or drops in current.

Applications for the SL08 7R002

The SL08 7R002 is suitable for a number of applications, such as motors, lighting, solenoid valves, and other motors that require current limiting. It is also well-suited for any application that requires a reliable current limitation and can handle temperatures up to +105°C. The SL08 7R002 can also be used in automotive circuits such as headlights, transmissions, alternators, and window motors as the thermistor has a high dielectric strength, allowing it to survive in higher temperature and vibration environments. In addition, the SL08 7R002 is also suitable for use in computers, home appliances, TVs, radios, and other audio/video equipment, as it is UL recognized and designed to meet the requirements of UL1575 and UL1877.

Conclusion

The SL08 7R002 inrush current limiter is a reliable and well-designed component that can help protect circuits from large inrush currents. It is suitable for a number of applications, and thanks to its high dielectric strength and UL recognition, it can be used in a variety of environments. If you\'re looking for a reliable and effective inrush current limiter for your circuit, then the SL08 7R002 is definitely worth considering.
