Through Hole Resistors

RSF5WSJB-91-820K Application Field and Working Principle

Through hole resistors are components used as electrical resistance in circuits. These resistors are placed in a hole drilled in a surface-mount circuit board, and are the most commonly used type of electrical components found in electronics today. Commonly available in fractional ohms (10k, 20k, etc.) and multiples of 10K (10K, 20K, etc.), these resistors are available in a variety of sizes and shapes, and are ideal for simple, low-power applications.The RSF5WSJB-91-820K is a type of through-hole resistor, also known as an axial resistor. This resistor is designed to reduce the total power that is transferred through an electrical circuit, and is ideally used in devices which require a stable, fixed amount of current to operate reliably. This type of resistor will limit the voltage and current passing through the circuit, preventing any components from becoming damaged due to an overload.The specific electrical resistance of this resistor is 820 kilo-ohms, with a range of roughly 775 to 867 kilo-ohms depending on certain variables. This resistor has a power rating of 5 watts, meaning that it can handle up to 5 watts of power and not become damaged. It also has a fairly high temperature rating, with a maximum operating temperature of 125 °C before its resistance begins to deteriorate.The RSF5WSJB-91-820K is designed for use in high-power applications, such as amplifiers, motor control, and other similar devices. As this type of resistor has a high tolerance to heat, it is well-suited for use with high-current circuits, such as those found in automotive, industrial, and consumer applications. The resistor is also designed to handle transient voltage spikes, further ensuring its reliability in high-power applications. The construction of this type of resistor involves winding the copper-wire leads around a ceramic core. This allows for a greater amount of stability in applications where there are high levels of vibration or mechanical shock, as the copper wire provides additional insulation for the resistor element. The copper-wire leads are then secured to the circuit board through soldering or a press-fit connection.In addition, the RSF5WSJB-91-820K is capable of providing superior electrical noise suppression, making it ideal for sensitive applications such as those requiring medical or scientific instruments. It is also extremely reliable, with an average failure rate of less than 0.5%.Through hole resistors such as the RSF5WSJB-91-820K are incredibly useful components as they are able to provide various levels of electrical resistance, allowing engineers to design and create circuits with a range of different power ratings and different levels of current and voltage. The myriad of use cases and the versatility of through hole resistors make them ideally suited for a variety of applications.
