Resistor Networks, Arrays don\'t just provide basic electrical resistance, they also offer many features such as achieving accurate voltage drops, dividing currents, improving signal to noise ratios and reducing electromagnetic interference. One type of network, the L083S471LF, has some unique features and characteristics that makes it a valuable component for a wide range of applications. The following text explains the L083S471LF application field and working principle.

The L083S471LF is a four-resistor network with adjustable resistance divider ratio. It is a surface mount network component used for dividing signals such as different types of voltages and currents. It is also designed for producing a precision voltage divider across a voltage input range from 0V to 6V. The network utilizes four resistor values, each from 0.02 to 0.22 ohms and two active elements: positive curvature zero TC NICs and low voltage low resistance S-type resistors. As well as being suitable for low to high current applications the network is advantageous because of its small physical size of 2.0mm x 1.27mm x 0.5mm which makes it suitable for PCB layout.

In terms of operation, the voltage across the network is divided in two states, a high-current state and a low-current state. The voltage transfer ratio of the network in the low-current state is determined by the resistor divider ratio. In the high-current state, the resistor divider ratio is determined by an additional circuit that includes two series connected S-type resistors. When a current is applied to the network, the conduction of the series connected S-type resistors, which acts as a current-sensing element, affects the voltage transfer ratio of the network because of an additional voltage drop.

This feature of the L083S471LF results in various advantages in application fields that require the voltage transfer ratio to be controlled by the current-sensing element. For example, in automotive applications, this element enables steering wheel audio volume control while maintaining constant volume recording. In other types of applications, such as robotics and home appliance control, the element helps maintain certain desired conditions like constant heating or cooling. It can also be used in automatic power supply systems such as a laptop computer charger, as the network can be used to detect the current level of the battery and adjust itself accordingly.

The L083S471LF is an extremely reliable resistor network because of its combination of high accuracy, low voltage divider ratio and adjustable voltage transfer ratio. Its design ensures that it is insensitive to temperature changes, making it suitable for industrial applications. It also has excellent electrical and environmental characteristics, including a high thermal resistance of greater than 200°C per watt, a low temperature coefficient of 55ppm/°C, and C0G temperature stability of ±15ppm/°C (which equals to ±0.00225Ω/K). As well as being insusceptible to environmental influences, it has a tolerance rating of 0.5%, making it perfect for high-precision applications.

In conclusion, the L083S471LF is a useful network component for a variety of applications. It offers superior features such as a low voltage divider ratio, adjustable voltage transfer ratio, low temperature coefficient and excellent electrical and environmental characteristics. Additionally, it is very reliable, making it well suited for uses such as audio systems, home appliances, automotive electronics and power supply control. It is an efficient and cost-effective solution for many applications, and its small size means it can be easily integrated into PCB designs.
