Resistor Networks, Arrays are widely used in electronic circuits and systems. The MPM20018001AT1 is a low-resistance, high-accuracy discrete resistor network with enhanced temperature performance. It is mainly used in electronic systems and circuits to replace fixed resistors and route signals.

Application Field

The MPM20018001AT1 is mainly used in electronic systems and circuits applications. It is designed for the communication networks, power amplifiers, signal conditioning circuits, digital to analog circuits, filters and instrumentation which require good accuracy and stability over a wide temperature range. The main features of the technology include low on-resistance, low absolute tolerance on resistance values, good temperature stability and excellent current capacity. It is also well suited for applications where high power dissipation is required as the heater element resistances can tolerate the large currents.

Working Principle

The MPM20018001AT1 resistor network is composed of two resistor elements, an active element and a heater element which are connected in series. When a voltage is applied to the network, the heater element produces heat and the active element generates a Current, and the two elements are electronically coupled together. The active element acts as a variable resistor while the heater element acts as a constant one. The current through the network will depend on the resistance at each element. The network provides precise resistance value adjustment by changing the resistance of the active element. By increasing the heater element current the resistance of the active element can be increased, resulting in a lower resistance of the network.

The MPM20018001AT1 offers a high precision alternative to replace fixed resistors in order to route signals and to provide high accuracy in signal conditioning and power amplifier applications. It is an ideal choice for applications requiring low resistance and high accuracy at temperature extremes and power dissipation rates.
