TC164-FR-072K87L

Resistor networks and arrays are electrical components which are designed to allow circuits to adjust to various operating conditions. As such, they are essential components in a wide range of devices, from appliances and toys to medical equipment and defense systems. One example of a resistor network is the TC164-FR-072K87L, a transistorized NPN silicon resistor array with a total resistance of 72K ohms.

The TC164-FR-072K87L is a four-resistor network that can be used in many different applications. Its most common application is as a high voltage current-limiting circuit, where it is used to monitor and adjust current levels. It is also used in power-supply switching and voltage-regulator systems, as well as a light-load resistor in audio amplifiers.

The TC164-FR-072K87L resistor network works by allowing electrical current to flow through the individual resistors in the network. The individual resistance of each resistor can be adjusted by changing the current levels of the circuit. This allows the network to adjust the total resistance of the circuit, which in turn allows the circuit to be tuned for different uses. For example, if the applied current is increased, the total resistance of the network can be lowered, thereby increasing its current-limiting capabilities.

The TC164-FR-072K87L resistor network also contains a protection diode to protect the network from over-current. This diode will kick in if the current in the network exceeds the network\'s rated current. The diode will then divert excess current away from the network, protecting it from damage.

The TC164-FR-072K87L resistor network is an essential component in many different devices. Its ability to adjust its total resistance allows it to be used for numerous applications, from high voltage current-limiting circuits to power-supply switching and voltage regulator systems. Its protection diode also ensures that it can safely handle higher currents than the network\'s rated current, providing the device with additional protection.
