<h2>Resistor Networks, Arrays</h2><p>Part Number 77083181P is a resistor network consisting of eight NTC Thermistors arranged in an array format. NTC stands for negative temperature coefficient, which is a type of resistor whose electrical resistance decreases with increasing temperature. The 77083181P is commonly used for temperature sensing applications as it ensures very accurate readings. It consists of two rows of four sensors, each one with an individual resistance step of 10 Ohms.</p><h3>Application Field</h3><p>As mentioned, the Part Number 77083181P is mainly used for temperature sensing applications. Specifically, its application fields include temperature measurement in industrial controls, motor control systems, dishwasher and washing machines, air conditioners, and ice makers. Additionally, it can be used for maintaining the parameters of temperature and air humidity in the processes of calculating, storing and displaying data.</p><h3>Working Principle</h3><p>The Part Number 77083181P operates using a voltage divider principle. A voltage divider is an electrical circuit used to divide a voltage into different sized parts. It consists of two resistors connected in a series. When a voltage is applied across the two resistors, a fraction of the total voltage appears across each resistor depending on its value.</p><p>The Part Number 77083181P resistor network consists of 8 resistors and is formed in a bridge type structure. When a voltage is applied and the outer four resistors are connected to ground, the point between the two inner resistors is the output. The voltage in each of the inner resistors is proportional to the opposite side resistors. The total voltage is divided at eight temperature sensing positions, with each position having a 10 Ohm step resistance change between them. By measuring the voltage between each of the eight points, the temperature can be determined accurately.</p>The specific data is subject to PDF, and the above content is for reference
