Resistor Networks, Arrays

CRC3A4E680JT is a three-terminal, surface-mount resistor network. It contains four resistors that are connected in series with one adjustable resistor. The adjustable resistor can be set to any of 16 possible values, allowing the network to be tuned for various applications.

The device is designed to replace discrete component networks to reduce board space and decrease the number of assembly steps required. The device is constructed from an array of resistors that are laser trimmed during manufacture to create varying resistance values. This allows powerful, compact networks to be constructed, which are less prone to drifting with temperature changes than their discrete component counterparts.

The CRC3A4E680JT is part of the CRC2C series of resistor networks from TT Electronics. It is available in a standard or extended temperature range version, with the extended version being suitable for use in automotive and industrial applications.

While normally used as a voltage divider, the CRC3A4E680JT can be used for other applications, such as current limiters, signal conditioning, impedance matching, communication, distortion correction, and power control.

The working principle of the CRC3A4E680JT is relatively simple. It is based on the basic laws of electrical circuits. The device consists of four resistors that are connected in series. The adjustable/trimmable resistor is the fifth resistor in the network.

The adjustable resistor is used to tune the network to the desired resistance value. By adjusting the resistance of the adjustable resistor, the current through the device can be set to the desired value. This allows the device to be used for a variety of applications, such as those previously mentioned.

In addition to the adjustable resistor, the device includes three fixed resistors. These resistors are laser trimmed during manufacture to ensure precise resistance values. This helps to minimize the effect of temperature changes on the device.

The CRC3A4E680JT is an invaluable tool for engineers and designers due to its versatility and small form factor. It can be used for a variety of applications, including voltage dividers, current limiters, signal conditioning, impedance matching, communication, distortion correction and power control.

In conclusion, the CRC3A4E680JT is a three-terminal, surface-mount resistor network. It contains four resistors that are connected in series with one adjustable resistor, which is used to tune the device for various applications. The device also includes three fixed resistors that are laser trimmed during manufacture to ensure precise resistance values and minimize the effect of temperature changes on the device. Due to its versatility and small form factor, the CRC3A4E680JT is an invaluable tool for engineers and designers.
