Resistor Networks, Arrays

A RACF164DFT40K2 is a resistor array network specifically designed to protect semiconductor circuits from high voltage transients and power surges. It is a cost-effective and reliable solution for protecting sensitive electronic components. The RACF164DFT40K2 is primarily used in consumer electronics, industrial automation and test equipment, and automotive applications.

The RACF164DFT40K2 consists of 16 individual resistors connected in a network. Each resistor is connected to an external connection point, which is referred to as a drain terminal. The resistors in the network are connected in parallel so that the power surge or transient voltage is evenly distributed throughout the network. The resistors have a low resistance value so they can safely divert the transient voltage and dissipate it in the form of heat.

The RACF164DFT40K2 can be used to protect a wide range of semiconductor devices such as diodes, transistors, and analog and digital ICs. Its low resistance value allows the device to absorb a large amount of energy when current is present. This makes it an ideal choice for applications where the power surge is expected to be strong and large surges could potentially damage sensitive components.

In order to simplify the installation of the RACF164DFT40K2, each resistor is integrated into a single package. This makes it easy to mount the device onto a printed circuit board (PCB). Once installed, the device forms a shielding network around the semiconductor components, ensuring that they are adequately protected.

The working principle of the RACF164DFT40K2 is based on the principle of resistive voltage divider. The resistor network is connected in parallel with the semiconductor device and the power supply. When a high voltage transient or power surge occurs, the voltage in the circuit is divided between the power supply and the resistor network. The resistors in the network absorb the excess energy and dissipate it in the form of heat. This prevents the voltage in the circuit from exceeding its maximum rating and damaging the on-board components.

The RACF164DFT40K2 also offers additional benefits such as reduced EMI (electromagnetic interference) emissions, improved board-level reliability, and improved power dissipation capability. With a low resistance value, the device can easily handle high current surges and reduce the EMI that is produced by them.

Overall, RACF164DFT40K2 is a cost-effective and reliable protection solution for semiconductor devices. It is easy to install and offers protection from high voltage transients and power surges. Its low resistance value allows it to dissipate a large amount of energy from the transient, ensuring that the on-board components remain safe from damage.
