Through Hole Resistors: RWR81N4640FRS70 Application Field and Working Principle

Through hole resistors are passive components used to provide electrical resistance by creating an obstacle to the flow of current in an electronic circuit. They are widely used in almost every type of electronic device and come in many different forms, one of which is the RWR81N4640FRS70.The RWR81N4640FRS70 is a type of through hole resistor designed for low power applications. It features a ceramic body, a graphite film coating, and an insulated metal lead frame. This resistor is available in various values and packages, with the most popular package being the SMD (surface mount device). The package size indicates the wire diameter, as well as the spacing between leads, for which the RWR81N4640FRS70 is specified to maintain a minimum spacing of 0.4mm. The resistance values of this component range from 10Ω up to 10000Ω in 1Ω increments.The RWR81N4640FRS70 is mostly used in monitoring, motor control, microcomputer systems, and digital communication systems. It is particularly suited for use in low power applications due to its low working power of only 0.08 Watts and its excellent performance in high frequency range (up to 50 MHz). Furthermore, the device offers good temperature coefficient and high resistance stability, which makes it ideal for use in temperature and voltage sensitive applications.In terms of its operation, the RWR81N4640FRS70 works on the principle of ohmic resistance. It prevents the excessive flow of current in a circuit by creating an obstacle in the path of electrons. This obstacle converts some of the energy of the electrons into heat, thus reducing the current.The RWR81N4640FRS70 features a variety of different package types, including boxed, bulk, and SMD. This allows for versatile use in applications requiring a high degree of flexibility. Furthermore, the device is also available with an optional case, which incorporates a heatsink, thereby helping to dissipate any generated heat from the component, ensuring greater stability and reliability. Another feature of the RWR81N4640FRS70 is its high current capacity, allowing for currents up to 10mA in load conditions. This is further enhanced by its low drift characteristics, which ensures that the device is able to maintain its resistance value even when exposed to high temperatures or voltage fluctuations.In short, the RWR81N4640FRS70 is an excellent choice of through hole resistor for low power applications, offering excellent performance, stability, and reliability. Thanks to its wide range of package types, it can be used in a variety of electronic devices, making it a popular and versatile choice.
