Inrush current is a surge current that occurs at the moment of electric power supply to all kinds of electrical equipment. It is necessary to limit inrush current of electrical loads to protect them from damage, system stability and to reduce voltage fluctuation. To mitigate the inrush current, Inrush Current Limiters (ICL) are used.

SL15 2R507 is an Inrush Current Limiter produced by Bourns Inc. The component features a low resistance, temperature coefficient and precision, together with high power dissipation. SL15 2R507 has an operating temperature range of -55°C to 125°C.The resistance of this component can be adjusted from 20Ω to 40Ω. It is ideal for applications such as computer motherboards, automotive powertrain assemblies, automotive lighting power supply, power cord assemblies, telecommunications equipment, and portable electronic devices.

The working principle of SL15 2R507 is based on the sensing of a surge current by its internal Nickel-Chromium resistor. When surge current happens, the temperature of the Nickel-Chromium resistor increases and it reaches its Curie temperature gradually. Consequently, the resistance of the resistor increases, limiting the inrush current before it reaches the equipment. After the surge current passes, the temperature of the resistor reduces and reaches its original resistance again.

SL15 2R507 has many advantages. It is an ideal choice for replacing ceramic chip resistors as it offers a higher power dissipation and the ability to operate up to a maximum temperature of 125°C. It is suitable for meeting the higher power requirements of large current inrush applications. Furthermore, its combination of low resistance and thermal management makes it suitable for use in many situations where it is used to control the current flow.

In conclusion, SL15 2R507 is an Inrush Current Limiter produced by Bourns Inc. Its working principle is based on the sensing of a surge current by its internal Nickel-Chromium resistor. The SL15 2R507 has many advantages such as its ability to operate up to a maximum temperature of 125°C, its low resistance, and its thermal management capabilities, which make it suitable for many current inrush applications.
