This device has a wide range of applications and its working principle is based on the characteristics of resistors.

Applications

The main applications of the 4605X-101-112LF are in maximum power point tracking (MPPT), power supply sequencing, precision power amplifiers, switching regulators, and imaging equipment. Using this device for the above-mentioned applications provides an accurate, high-frequency bandwidth, robust and reliable solution, along with a wide range of resistance values, temperature coefficient of resistance (TCR) and tolerance.

The 4605X-101-112LF is also used in switch mode power supplies (SMPS) where this device is used as a front-end filtering circuit, as it provides an efficient impedance matching solution since the device features a low output impedance that can provide protection against EMI (electromagnetic interference). Moreover, this device is used in surge protection circuits, where the device is provided with a high surge protection level, that provides effective protection from voltage spikes.

Working Principle

The basic principles of the 4605X-101-112LF can be applied to any resistor network. An array of resistors (generally arranged in a bridge or ladder configuration) is connected in series and/or parallel across a source of voltage. When a current is applied to the network, a certain amount of power is consumed by the resistors which results in a drop in voltage across the resistor. The current and voltage can then be measured at each individual resistor in order to calculate the resistance.

The 4605X-101-112LF utilizes the series and/or parallel resistances of the four-terminal array, allowing for accurately matched paralleled and intuitively matched series resistors, which enables the device to be used for accurate signal conditioning or matched resistance in a variety of applications. The device features very low output resistance, providing a very precise and accurate output voltage value even at high frequencies.
