RACF164DJT1K50

The RACF164DJT1K50 is an advanced resistor network, array or device designed for those looking for the most advanced solutions and features in an array circuit package.

The RACF164DJT1K50 resistor array is a fully automated, single-pin integrated resistor array specifically designed to solve common board area and interface problems often found when using conventional fixed value resistors.

This RACF164DJT1K50 resistor network includes two separate series of small, closely-spaced, ceramic-on-polyimide resistors that are connected in parallel within a small package height. This resistor network produces a “known” resistance selected from 16 pre-set values in the range 1kΩ to 50kΩ. The desired resistance value can be selected using external voltage and current-sense lines.

The resistor array is ideal for applications requiring smaller PCB package sizes without sacrificing space on the board, and due to its integrated nature, the RACF164DJT1K50 requires fewer components, less plugging and soldering, and lowers the rolling cost.

In terms of application field, the RACF164DJT1K50 is suitable for various industrial, commercial, automotive, and consumer electronic equipment, such as car audio systems, 3G cellular handsets, and Bluetooth devices. It benefits from its versatile design that allows for low-resistance values to be accurately tuned through external voltage and current-sense lines for precision applications such as current sensing or power monitoring.

The RACF164DJT1K50 also offers a broad range of resistance values and power, enabling designers to function in different resistor arrays for future use in any application. The 1% tolerance of resistor values ensures accuracy and guarantees that the results are repeatable and reliable, making it suitable for audio, communication applications, and heavy-load electronics.

The working principle of the RACF164DJT1K50 is relatively simple. It consists of two separate series of small, closely-spaced, ceramic-on-polyimide resistors that are connected in parallel within one small package. Through the external voltage and current-sense lines, an applied voltage determines the resistance value of the chip. The larger the voltage, the higher the resistance value and vice versa.

When the voltage applied to the external voltage line and current-sensing lines is held constant, the value of the resistance will remain steady. This resistance value may be varied again by changing the applied voltage, allowing for infinite adjustability. This same principle may be used to construct a voltage divider, allowing the voltage division ratio to be adjusted as needed.

The RACF164DJT1K50 is among the top picks of resistor networks or arrays available today. Its comprehensive selection of resistance values and advanced features meet a variety of needs, achieving reliability and accuracy at the same time. Thanks to its integrated nature, the cost-saving potential of using this integrated resistor array is evident.
