Through Hole Resistors: RWR89S1211FRS70 application field and working principle

Through hole resistors are a type of electronic component used to limit the flow of electricity through the circuit. They are mounted in an insulating material which, when current passes through it, creates a resistance. These resistors have become more popular in recent years due to their superior performance, lower costs, higher reliability, and ease of installation in circuits.The RWR89S1211FRS70 is a through-hole resistor that has been specifically designed for long-term reliability in a wide range of applications. It features a heavy-duty construction that consists of an epoxy-filled ceramic body and a conductive path. The epoxy-filled ceramic body ensures that the resistor does not suffer from vibration or temperature-related stresses.The RWR89S1211FRS70 is the most popular kind of through hole resistor used for motor, inverter, and pulse control applications. It is usually used in applications that require low power dissipation, such as lighting, and other low-power electronics. Its operating temperature range is -25C to +70C, and its current rating is 1.5A with a maximum voltage rating of 30V.In terms of its working principle, when electric current is passed through the resistor, it creates a voltage drop across the resistor. This voltage drop is inversely proportional to the current, meaning that the more current that goes through the resistor, the higher the voltage drop. The resistor also dissipates power, which is equal to the voltage across the resistor multiplied by the current that flows through it.The RWR89S1211FRS70 is an ideal component to use in applications with low power dissipation and temperature requirements. Its heavy-duty construction ensures that it is robust and reliable, while its epoxy-filled construction makes it resistant to temperature changes. Therefore, the RWR89S1211FRS70 is an excellent choice for applications that require the utmost reliability.
