Resistor Networks, Arrays offer a convenient way of implementing resistor networks and therefore they are used in many different applications for purposes such as current limiting, voltage dividing, impedance matching, signal conditioning, etc. The CRB3A4E470GT is a recently developed integrated packaging solution for resistor arrays in the form of a chip. It offers a mix of low-profile SMT-mountable packages, signal-conditioning capabilities and long-term reliability.

Application Field

The CRB3A4E470GT is typically used for voltage stabilization and surge suppression in automotive and portable communications applications. It is also suitable for a range of general-purpose signal-conditioning applications such as impedance matching, voltage-divider networks, current limiting, and so on. With its low-profile SMT-mountable package, it\'s an ideal solution for integration into electronic systems with limited space and thermal constraints.

Working Principle

The CRB3A4E470GT is composed of two chips: a resistive-array chip and a bridge-circuit chip. The resistive-array chip integrates multiple resistor elements onto a single chip and is used to form a voltage divider or current-limiting network. The bridge-circuit chip is used to provide galvanic isolation between the two sides of the divider circuit. The resistor elements in the array can be configured in different ways depending on the specific requirements of the application. The bridge-circuit chip can also be used in conjunction with a capacitive element to provide further frequency-dependent attenuation for noise-suppression purposes.

The CRB3A4E470GT is highly reliable and well-suited for a variety of applications. The integrated packaging solution saves space and allows for easy integration into systems with limited space and thermal constraints. With its low-profile SMT-mountable package, it is an ideal solution for implementation applications requiring high-density interconnectivity.
