SL12 15004

Inrush current limiters (ICL) are a type of electrical device used to reduce the amount of current drawn when power is first applied to a circuit. They are commonly used in applications where large capacitors are charged, such as in power supplies and systems that require an electrical charge, such as starter motors and inverters.

The SL12 15004 is a made inrush current limiter specifically designed for use in applications where sensitive components or circuits require protection from over-current. This device consists of a resistive element, commonly a metal oxide film resistor or thin film resistor, connected in series between the source and the load in an electrical circuit. When the voltage is applied, a large amount of current flows through the resistor element, reducing the total current in the circuit to the desired level.

In order to protect sensitive components from inrush current, several different types of ICLs are available. These include non-linear resistors, thermistors, metal oxide varistors, PTCs (positive temperature coefficient) resistors, and semiconductor fuses. Non-linear resistors, such as metal oxide film or thin film resistors, are normally used in conjunction with a diode in order to prevent the current from rising too high, while PTCs and thermistors are used to regulate temperature of the circuit. Semiconductor fuses work by limiting the amount of current passing through the circuit by fusing the circuit if the current exceeds a preset level.

The SL12 15004 inrush current limiter is a thin film resistor designed for protection of sensitive loads from over-current. It is a low cost, low power device which provides excellent performance in a variety of applications. The device is available in different wattage and resistance levels, with wattages ranging from 4W to 8W and resistance levels ranging from 0.5Ω to 3Ω. The device has a rated voltage of 500V and a maximum current of 10A. The device also has a wide operating temperature range, from -40°C to +125°C.

The working principle of the SL12 15004 inrush current limiter is simple. When power is applied to the circuit, an initial surge of current passes through the device. This current is regulated by the metal oxide film resistor, thus reducing the current in the circuit and protecting the sensitive components from damage. The device is designed in such a way that the current is automatically reduced as the voltage increases, thus protecting the components from high voltage situations.

The SL12 15004 inrush current limiter is an ideal choice for protecting sensitive components from over-current. It is low cost, low power and provides excellent performance in a variety of applications. It can be used in applications such as power supplies, electronic circuits, automotive systems, and other applications where protection from inrush current is desired.
