What is CAT16-1100F4LF?
CAT16-1100F4LF is a resistor network or resistor array manufactured by Texas Instruments. It is a 4-terminal array of five identical 100 kΩ resistors. Due to its high power frame, the network is particularly well suited for applications where high power dissipation is required. The device has two unique characteristics: a low parasitic island and a low thermal resistance.
Application Field
CAT16-1100F4LF resistor networks are designed for a variety of applications. Its low thermal resistance allows it to be used in temperature-sensitive applications such as automotive, medical, and industrial systems. The device is also commonly used for precision voltage dividers, termination networks, and measuring devices, such as current sensors. The low parasitic island provides minimal signal path interference, making the network suitable for filter networks and precision current sensing.
Working Principle
The CAT16-1100F4LF resistor network is composed of five identical 100 kΩ resistors, each of which is connected to a different terminal. This creates a four-terminal resistor array. When the network is wired up correctly, the four terminals form two pairs of resistors: two terminals containing two series connected resistors, and two terminals containing two shunt connected resistors. The two series resistors are referred to as a voltage divider, while the two shunt resistors are referred to as a current divider.
When the resistor network is used with an AC source, an AC voltage is applied across the voltage divider, and an AC current is applied across the current divider. This produces a voltage and current across each respective terminal and can be used to measure the AC voltage and AC current across the resistor network. This is how the resistor network is able to determine the AC voltage and AC current applied across it, as well as measure the resistance of the resistor network.
Conclusion
CAT16-1100F4LF is a 4-terminal resistor array manufactured by Texas Instruments. It is designed for a variety of applications, from temperature-sensitive systems to precision current sensing. The device is composed of five identical 100 kΩ resistors, which creates two pairs of series and shunt resistors. It is this configuration that allows the network to measure the AC voltage and AC current across it. By taking advantage of this feature, this device provides a reliable way to measure various electrical characteristics.
