Resistor Networks, Arrays and the MC4-5007KE

Resistor networks and arrays offer a range of functionality which means they are often selected for application areas which require precision in terms of resistance, responsiveness and accuracy. On the other hand, when selecting these components, one of the key criteria for many designers and engineers is reduced component size, as the overall footprint, and its associated cost of manufacture, can be a significant factor in selecting a component.

The MC4-5007KE resistor network is a SMD (surface- mount device) offering a range of valuable features for electronic design. The MC4-5007KE 0805 package measures just 1.25mm x 1.25mm x 0.65mm and despite its size, offers exceptional performance. Its four pins allow electrical connections on both sides, and when used with an FR-4 compliant substrate, the MC4-5007KE is compatible with most current rise-time-compensated applications.

Utilising a multi-layer configuration, the MC4-5007KE incorporates 8 networks of SMT resistors, each of which can be configured to provide an ideal value of resistance. Additionally, due to its low-profile design, the MC4-5007KE is suitable for high voltage applications, and can be used for resistance measurements when it is connected in an AC measuring bridge – as well as being highly resistant to both ESD and EMF.

The MC4-5007KE is a four-layer, resin-molded network with two resistors, four jumpers and two multi-turn precision elements. This combination of components provides a secure connection with solid reliability, and it also offers excellent insulation characteristics. The combination of the components, and their placement within the network, also allows the MC4-5007KE to provide high burst currents, and the device can even be used in high-voltage pulse applications.

The network also incorporates an active metal layer which helps protect against static effects, which can cause problems in applications running in corrosive environments. The two resistive contacts, located at the center of the network, are formed from a very thin oxide coating, which allows for accurate and repeatable resistance measurements. This oxide layer also helps to keep the contact resistance constant, even when exposed to harsh environmental conditions.

The MC4-5007KE is an ideal solution for many applications which need to utilise resistor networks or arrays, offering the accuracy which is often required, but with a more compact overall package size. Its multi-layer configuration, combined with a highly reliable oxide-coated resistive contact, also helps to protect against environmental effects, and the device can operate effectively with high levels of resistance, even in high voltage pulse applications.

Gigaray, one of the leading manufacturers of SMD networking components, have developed a range of products based on the MC4-5007KE resistor network. By combining the device with a range of other components, designers can create SMD-based solutions which offer maximum performance with minimal physical footprint. With Gigaray’s range of options, it is possible to create smaller and more efficient networks and arrays, which can be used in a wide range of applications.
