It can be used in automated manufacturing, for controlling motors, heating elements, fuel injectors, robotic actuators, and for sensors in medical and automotive applications. In addition to its use in industrial and automation applications, CRA06P08375R0FTA can also be used in portable devices, consumer electronics, audio and telecommunications applications. CRA06P08375R0FTA is available in 0 ohms to 5k ohms range with tolerances from 0.05% to 10%. The product can also be supplied in multiple pin configurations from 2pins, 3pins, 4pins and 5pins.

Working Principle

CRA06P08375R0FTA resistor arrays are based on thick film screen printing technology with the resistors printed on ceramic substrate. The resistor network consists of a matrix arrangement of resistors with a common bus, which is connected to the ground, and each resistor is connected to the PCB board through its respective terminal pin. The two main functions of CRA06P08375R0FTA are to provide a high-value resistance in a single assembly, and to protect against EMI/RFI noise. The thick film screen-printed on the substrate film provides the resistive value and the terminals are connected to the substrate giving the necessary electrical connections.

The value of each resistor within the network is fixed and can be obtained by calculation. The resistance values are calculated in base on the resistivity of the substrate and the physical dimensions of the resistors. The substrate material can be selected according to the desired electrical requirements. The physical size of the array is dependent on the number of resistors the network has, and the resistance tolerance is determined by the size and number of resistors used.

The design of CRA06P08375R0FTA also provides surge protection. The resistor network substrate is manufactured from high quality, dielectric material, and its construction is designed to protect against EMI/RFI noise and ESD. These features make CRA06P08375R0FTA suitable for a wide range of applications, allowing a more reliable design and increased performance.
