Working Principle

The 4308R-102-394 features eight resistor elements in a 3x3 array configuration. The eight resistor elements are connected in series across the two input and output ports by a metal trace located on the top side of the device. The top trace is designed to reduce the inductance of the connection between the resistor elements and the ports. On the bottom side of the device, the eight resistors are connected using another metal trace. This trace is designed to minimize crosstalk between the resistors and to reduce the switching noise.

Each resistor element can be adjusted manually by turning the corresponding robotic screwdriver located on the device. The user can adjust the resistance of each resistor element individually. The adjustment range is from 0 to 30 ohms, and the adjustment resolution is 0.1 ohms.

The 4308R-102-394 is designed to provide excellent temperature stability and low temperature coefficient, with a typical value of 5 ppm per degree Celsius. This makes it possible to use the 4308R-102-394 in applications where temperature control and stability is critical.

The 4308R-102-394 has a high pulse and avalanche load capability with a typical voltage rating of up to 70 volts. This makes it suitable for applications where high voltage and high power handling capabilities are required.

The 4308R-102-394 also features a fast response time, with a typical response time of 0.1 milliseconds. This makes it suitable for applications where speed is required.

The 4308R-102-394 is lead and RoHS compliant, making it suitable for use in applications where environmental compliance is critical.

The 4308R-102-394 is an excellent choice for applications requiring a high degree of accuracy, high pulse and avalanche load capabilities, high voltage capabilities, fast response time, and compliance with environmental regulations.
