PSM400JB-2K2

Through hole resistors are one of the most basic and widely used components in electronic circuits. PSM400JB-2K2 is one of the LED type through hole type resistors which is widely used in many applications. This article will discuss the applications and working principle of PSM400JB-2K2.

PSM400JB-2K2 is a 4mm square type of through hole resistor with pins on both ends. It is a single resistor package, and its pins are gold-plated with gold nickel alloy. It has a power rating of 1W to 2W, and has a resistance range of 100ohms to 2K ohms. The tolerance of this through hole resistor is ±2%. It is rated for 125°C and it’s temperature coefficient is ±100ppm/°C. It is also available in a variety of package sizes depending on the requirements of the circuit.

PSM400JB-2K2 is widely used in many applications, such as low-power voltage dividers. It can also be used as a current-sensing resistor in power supply designs because of its low tolerance. It can be effectively used in pulse-width modulation circuits as well as in rechargeable batteries for monitoring cell-voltage levels. It can also be used in other applications where high-voltage or current is present such as flyback transformers or over-voltage protectors.

The working principle of PSM400JB-2K2 is similar to that of any other through hole resistor. It works by introducing electrical resistance into a circuit, which reduces the current flow and voltage drop across the component. As a result, it dissipates the energy as heat that is produced due to the flow of current across it. The dissipated heat is proportional to the power rating of the component, which is one of the major factors when choosing a resistor for any application.

One of the main advantages of PSM400JB-2K2 is its low resistance tolerance, which makes it a great choice for precision applications. Moreover, it has a high power rating, making it suitable for use in most power supply circuits. In addition, its gold-plated pins ensure excellent electrical contact with the components it is connected to.

In conclusion, the PSM400JB-2K2 is one of the most versatile and reliable through hole resistors. It is widely used in many applications due to its low resistance tolerance and high power rating. Additionally, it is very easy to install and maintain, making it a great choice for most electronic circuits.
