Resistor Networks, Arrays, the SM2X9K000/1K000FA application field and working principle.

Resistor networks, also known as resistor arrays, are mounted on a single device to allow multiple resistors to be connected together without the need for soldering or the use of a circuit board. This makes them ideal for use in compact, space-saving configurations. The SM2X9K000/1K000FA is a series of miniaturized resistor network devices, used mainly for automotive applications like airbag sensing.

The SM2X9K000/1K000FA has 7 resistors which are connected in series and yet highly accurate. It has a maximum rated power of 0.125 W and a ІО characteristics in the range of 8 ohms to 800 ohms per resistor. The resistors are fitted in a compact, single body container, and feature a rugged, glass-epoxy construction.

The working principle of the SM2X9K000/1K000FA is relatively simple. It consists of two identical resistors connected in series which create a voltage divider network. This voltage divider network is then connected to the two ends of the array, which complete the circuit. Consequently, when the voltage across the array is applied, a current will be drawn due to the potential difference created by the resistors. This current is then used to generate a feedback signal to the Airbag Controller.

Applications of the SM2X9K000/1K000FA includes airbag sensing, voltage reference circuits, voltage level translators, and temperature compensating circuits. They offer significant performance advantages over discrete resistor combinations. They are particularly useful in automotive applications, as they provide resistance values with an accuracy that is difficult to achieve using a combination of individual resistors. Other advantages of the SM2X9K000/1K000FA include a wide range of resistance values, low power consumption, and good thermal stability.

In conclusion, the SM2X9K000/1K000FA is a series of miniaturized resistor networks, mainly used for automotive applications. The working principle is based on the voltage divider network, and the applications include airbag sensing, voltage reference circuits, and temperature compensating circuits. The advantages of the SM2X9K000/1K000FA include a wide range of resistance values, low power consumption, high accuracy, and good thermal stability.
