A through hole resistor is a type of resistor that is characterized by its ability to physically anchor the resistor to a printed circuit board (PCB) or other electronics device and providing a secure and stable connection. The PSM900JB-220R is a through hole resistor that is widely used in various applications. This article will discuss the applications of this resistor as well as its working principle.

PSM900JB-220R Applications

The PSM900JB-220R is a surface mount resistor, meaning that it is designed to be mounted onto the surface of a PCB. This type of resistor is commonly used in a wide range of applications, including power electronics, communications, industrial and automotive applications. Common uses for this type of resistor include: controlling power input in an automated system, providing voltage or current protection against high power draw, and filtering or dampening high frequency signals.

Working Principle

The PSM900JB-220R is a carbon film resistor. Carbon film resistors are constructed from a thin film of carbon, which is applied to an insulating substrate. The substrate material typically consists of either glass, ceramic, or plastic. The rate at which electricity flows through the resistor is determined by the amount of carbon that is applied to the substrate. Lower amounts of carbon provide higher resistance values. Higher amounts of carbon provide lower resistance values.

The function of the resistor is to limit the flow of electricity. Depending on the application, the resistor is designed so that it can limit the current to a desired amount. The most common type of resistor is a single-pole resistor, which has two connections, one connected to a positive voltage source and the other connected to a ground source. When current travels through the resistor, it is limited by the total resistance value, which is determined by the substrate material and the amount of carbon applied.

Power resistors are usually designed to dissipate heat, and in some cases they are designed to have a low resistance value. However, they can also be designed to accommodate higher power applications. In such applications, they are designed with higher resistance values and with materials that have higher thermal conductivity. This allows the resistor to dissipate the heat generated by high currents more efficiently.

Conclusion

The PSM900JB-220R through hole resistor is a highly reliable and versatile component that is widely used in a variety of industrial and consumer applications. It is generally composed of a thin film of carbon which is applied to an insulating substrate, and its resistance value is determined by the amount of carbon applied. The function of the resistor is to limit the current to a predetermined value. This article has outlined the applications of the PSM900JB-220R, along with its working principle.
