Resistor Networks, Arrays

The CRB3A4E161JT resistor network devices might have slipped past your notice, but they are definitely an integral part of everyday electronics. Fast becoming the standard solution for signal processing, control, low-noise, voltage regulation, and other functionality across many electronic applications, these resistor networks also offer higher reliability and precision than other general-purpose components. In this article, we take a closer look at the functions of the CRB3A4E161JT and the applications for which it is suited.

The CRB3A4E161JT is a precision resistor network device manufactured by KOA Speer. It is made up of three metal-insulator-metal (MIM) layers of 16 resistors with a resistance of 0.1 Ohms and ±2% tolerance. These in-line networks are designed to be used for signal differentiation, signal splitting, precision signal amplification, and more. The device is available with a wide array of options, including both normal lead spacing and low-profile designs and pitch sizes ranging from 0.02mm to 0.2mm.

The CRB3A4E161JT’s primary function is to provide a high degree of accuracy in precision resistors. With its MIM configuration, the device offers excellent isolation between individual resistors and better stability than most other components. Its tight tolerance ensures that it can effectively attenuate and spread signals at just the right rate, while its high purity ensures reliability and minimal chemical drift. The device is also rated for ESD up to 8kV, making it more resistant to ESD-induced damage than many other components.

Perhaps the most outstanding feature of the CRB3A4E161JT is its wide range of potential applications. It is suitable for use in a variety of analog circuits, from low-noise amplifiers to voltage divider networks, as well as digital circuits, such as pulse-width modulation or comparator applications. With its high precision and low signal attenuation, the device is ideal for precision signal processing applications, particularly in applications that require high accuracy and resolution. It is also a popular choice for use in sensor-based electronics, as it can provide the precise resistances needed for accurate readings.

The working principle of the CRB3A4E161JT is quite simple. The device consists of three layers of MIM resistors connected in series, each with separate but identical resistance values. At the incoming signal, the capacitors of each layer send pulses of positive and negative voltage alternating relative to each other, which creates a low-resistance channel. As the signal passes through the resistor network, each layer works to reduce the signal amplitude in a variably decreasing manner. This process ensures a linear decrease of the signal-to-noise ratio until it reaches its desired level.

In conclusion, the CRB3A4E161JT resistor network devices provide precision signal processing, low-noise amplification, and voltage regulation capabilities, along with a suite of features tailored to suit a broad range of applications. This device is well suited for use in digital and analog circuits, and its ESD protection and precision resistors guarantee reliable operation and accuracy. With its tight tolerance and high-purity layers, it is certainly a cost-effective solution for a variety of applications.
