4114R-1-202

Resistor Networks, Arrays are electrical components that are used to form a defined electrical resistance level. Although individual resistors may be used, network-type resistors are generally preferred since they are designed to offer more accuracy and a higher degree of protection against eventual damage. The term 4114R-1-202 refers to a specific type of network resistor constructed from thin-film technology and is characterized by its low power and great stability.

Application Field

The 4114R-1-202 is primarily used as a medium-power load resistive element in various electronic circuits, and for impedances across a wide range of frequencies, due its low profile. In addition, it is widely used for impedance matching, power factor corrections, and as an inductance or capacitor substitute. As a medium-power element, its main applications include power supplies, DC-DC and AC-DC converters, LCD televisions, computers, automotive display modules, and charging systems.

Working Principle

The 4114R-1-202 network resistor consists of a high-resolution, multi-resistor network mounted onto a single chip. This type of network resistor is designed to provide accurate and reliable resistance values, even when exposed to high heat and voltage levels. It is particularly well suited for medium power applications due to its low working temperatures and reliable long-term performance.

The 4114R-1-202 network is composed of a number of thin-film resistor elements in series or parallel, depending on the desired resistance value. A thin-film resistor is composed of an electrically resistive material, such as a metal or alloy, that has been applied in a thin film format to a ceramic substrate, then heated and cooled rapidly in a process called "sintering" to form a highly precise and homogenous resistor element. This is then connected to the other elements of the network to produce the desired resistance value.

The 4114R-1-202 network is designed to provide excellent directional stability under high temperature and voltage, to maintain consistent resistance values over time, and to provide a high degree of immunity against air pollutants. It also features a very low TCR (temperature coefficient of resistance) and high stability over a wide range of frequencies. This provides significant stability in terms of impedance, voltage, and current, allowing for accurate performance in various type of electronics systems.

Conclusion

The 4114R-1-202 network resistor is a highly reliable and extremely stable component that is ideal for medium power applications in various electronics devices. By utilizing its thin-film technology, it offers excellent directional stability, low TCR, and a wide range in terms of resistance ranging from 1 kΩ to 10 MΩ. By having these features, it is well suited for applications such as impedance matching, power factor corrections, and as an inductance or capacitor substitute.
