RNA4A8E680JT

Resistor Networks, Arrays are composed of assemblies of resistors connected in some particular topology in order to provide specific resistance to a signal path or to provide voltage dividing capabilities. The high precision or harsh environment requirements and specific feature needs associated with many types of production equipment can often demand the use of resistor networks. This article is focused on the application field and working principle of the resistor network RNA4A8E680JT.

RNA4A8E680JT is a 4-ohm 8-resistor network package with size of 4.25 x 1.5mm and total resistance of 64 ohm. It is suitable for applications requiring resistance values between 4 and 64 ohms in an ultra-small form factor. The resistor network package is constructed using four resistor elements mounted onto a 4-pin package. The individual resistors are selected for tight tolerance (+/-1%) and overall balance. The package is designed to dissipate up to 125mW in an operating temperature range of -55°C to +125°C.

The primary application for the RNA4A8E680JT is in telecommunication systems where the package is often used in line matching circuits to match the impedances in off-hook telephone lines, subscriber loops and circuit splitter segments. It is also used in instrumentation equipment, aerospace systems, and medical devices. The package is RoHS Compliant and can be manufactured with lead (Pb) free components and soldered interfaces.

In terms of its working principle, the resistor network consists of 4 isolated resistors in series and is covered with silver paste. Its resistors are self-adhesive on the surface, which makes them suitable for easier assembly in circuit designs. The resistor network is based on a high precision technology with 4 points of which the resistance values can be programmed. The device itself is built with standardised 4-pin connectors, each pin representing a resistor that can be programmed from almost 100 ohm to 1 kohm. The resistance value for each resistor can also be programmed while the overall resistance of the entire network can be adjusted through the selecting of the correct resistors.

The device is capable of providing a wide range of resistance values that can be used in different electrical components, from signal generators to transmission lines. The device is also able to maintain its accuracy and will not change its value overtime. Moreover, due to its smaller size, the resistor network can be used in confined spaces.

To summarise, the resistor network RNA4A8E680JT is a small 4-pin package that offers resistance values up to 64 ohm. Its small size makes it suitable for applications in telecommunication systems, instrumentation equipment, aerospace systems and medical devices. The device is composed of 4 isolated resistors that are self-adhesive and have a total resistance range of almost 100 ohm to 1 kohm. It offers high precision and has a wide range of applications due to its accuracy and small size.
