Introduction

Through-hole resistors are resistors with leads that can be directly inserted and soldered into a printed circuit board (PCB) in order to connect two or more circuits. These resistors are used for a wide variety of applications, such as power supply regulation, signal conditioning and protection, and transducer signal conditioning. One of the most common types of through-hole resistors is the RSF100JT-73-91R, a precision, power-rated through-hole resistor.

RSF100JT-73-91R Overview

The RSF100JT-73-91R is a precision, power-rated, lead-based through-hole resistor. It has a tolerance of +/-1%, a power rating of 10W, and a temperature coefficient of 0.4 ppm/°C. It also has a moisture resistance rating of 24 hours, which means it can withstand exposure to moist environments without degrading its performance. The resistor is available in single and multiple values from 0Ω to 10kΩ, and it is made from Moisture Proof Polyamide 1206 material.The RSF100JT-73-91R has wide application in electronic circuits. Its tolerance of +/-1% means it is stable and reliable enough for use in precision circuits. It also has a power rating of 10W, making it suitable for power supply regulation, signal conditioning and protection, and transducer signal conditioning. Finally, its temperature coefficient of 0.4 ppm/°C makes it useful for temperature-sensitive applications.

Working Principle

At the heart of the RSF100JT-73-91R is a resistor element, usually made from a metal alloy such as copper or nickel. When a voltage is applied to the resistor, an electric current will flow through the element. The current is proportional to the voltage and is inversely proportional to the resistance. This means that as the voltage increases, the current will also increase, and as the resistance increases, the current will decrease. The resistance value of the RSF100JT-73-91R is determined by the metal alloy in the resistor element and the size of the resistor element. The larger the resistor element, the lower the resistance, and vice versa. For the same metal alloy, the higher the temperature, the higher the resistance, and vice versa.

Conclusion

The RSF100JT-73-91R is a precision, power-rated, lead-based through-hole resistor that is used in a wide range of electronic applications. Its tolerance of +/-1%, power rating of 10W, and temperature coefficient of 0.4 ppm/°C make it highly stable and reliable. Its working principle is based on resistor elements with metal alloys, which determines the resistance value based on the alloy and the size of the resistor element. With its wide application field and stable performance, the RSF100JT-73-91R is an invaluable part of any PCB design.
