CAT10-560J4LF

Resistor Networks, Arrays

The CAT10-560J4LF is a fixed-value surface mount resistor network developed by NXP Semiconductors. It is capable of providing exceptionally high-current power solutions with low profile, excellent temperature stability, and high impedance. The resistor network is comprised of 10 elements in a 2 by 5 array.

The device is designed to be used in devices requiring current-limiting, power management, and voltage limiting. These applications may include protection circuits for power sources such as batteries, motor protection, and overvoltage protection. Additionally, the CAT10-560J4LF is widely used in power amplifiers and signal conditioning.

The network is based on four resistors of 560 ohms and six of 1560 ohms, arranged in two terminals, [R1-R4 ], [R5-R10], on each side of the 10-pin DIP package. The device is rated from -40°C to +105°C, allowing for reliable operation over a wide range of temperature environments. Because the resistance values are fixed, there is no need for an additional selection of resistors, making the network suitable for space-conscious designs.

The CAT10-560J4LF\'s working principle relies on negative temperature coefficients of resistance, also known as NTCs. NTCs are a type of temperature-sensitive resistor that decrease in resistance as temperature increases. In the CAT10-560J4LF, this resistance decrease is used to limit the current that passes through the device, thus limiting the power supplied to the connected circuit or device.

The resistors in the device dissipate heat over the network, reducing the current travelling through it. If more current is applied, this causes the resistors to heat up, further reducing the current. This self-regulating process allows for a smooth, stable power supply, without the need for complex control systems or additional components. The CAT10-560J4LF can also be used to limit the voltage applied to a connected circuit.

The CAT10-560J4LF is a cost-effective, high-performance solution for many power management and protection applications. It\'s small size, high temperature stability, and low profile make it an ideal option for devices such as portable and automotive applications. The device can also be used for low-profile antenna impedance matching applications.

The CAT10-560J4LF is an example of a fixed-value resistor network capable of providing robust, reliable power solutions. The device\'s performance is based on the negative temperature coefficient of resistance, allowing for self-regulating power management and voltage limiting. Its small size, high temperature stability, and cost-effectiveness make it an ideal choice for many applications, including protection circuits, power amplifiers, signal conditioning, and low-profile antenna impedance matching.
