4820P-T02-203

Resistor networks, arrays, and 4820P-T02-203 application fields and working principles have been developed over the years to improve the reliability and performance of electronic devices. Resistor networks are composed of a group of resistors that form electrical paths between two or more points of a circuit. Arrays are an arrangement of resistors connected in parallel or in series to form a voltage or electric current divider or voltage-summing network. The 4820P-T02-203 is a high-power application specific resistor network that is designed for high temperature operation. 

The 4820P-T02-203 is a surface-mount, multi-value resistor array that provides a single or multiple resistor configurations in one package. It consists of two linear, two-terminal resistors that are connected in series, and it is available in various resistance values. The 4820P-T02-203 is designed to provide a reliable connection in harsh environments and has a low profile design that allows for easy installation into tight spaces. It is ideal for applications such as power supplies, motor speed control, and other temperature-sensitive environments. 

The 4820P-T02-203 is designed to provide a temperature-stable and uniform current distribution in applications that require high power and temperatures exceeding 200°C. The device features a low thermal coefficient of resistance, which ensures that the resistance value remains constant over the rated temperature range. The 4820P-T02-203 also has a low temperature coefficient of resistance (TCR) that allows for wide temperature range operation with better accuracy. 

The 4820P-T02-203 is designed to operate in a voltage range from 16V to 300V. In addition, it has a low total impedance, which allows for higher power density and less power losses from the device. The 4820P-T02-203 is also designed to provide reliable and robust operation at high temperatures and has an operating temperature range of -55°C to +200°C.

The 4820P-T02-203 is designed with a robust construction that provides excellent electrical parameters and reliable performance. The device features two alloys for the resistive elements, a high-resistance NiCr and a low-resistivity NiFe coatings, making it suitable for high power applications. The NiFe alloy coating provides superior thermal dissipation and corrosion resistance, while the NiCr coating provides exceptional oxidation resistance.

The working principle of the 4820P-T02-203 is based on the resistance-capacitance (RC) network model. The device is designed to provide a constant current division across two resistive elements due to the displacement current between them. As the voltage applied to the device increases, the displacement current will become greater, causing the division of current across the two resistive elements to become more unequal. This produces a non-linear resistance-capacitance curve, which can be used to control the current flow in applications where precise current regulation is required.

The 4820P-T02-203 can be used in a wide variety of applications, such as power supplies, motor speed control, temperature sensors, and other temperature-sensitive environments. It is also suitable for applications where consistent power distribution is needed. The 4820P-T02-203 is a reliable, high-power application specific resistor network that is designed for high temperature operation and offers a wide temperature range and low profile design for easy installation.
