Through Hole Resistors are an often used and reliable form of resistors on a circuit board. They are mostly used for power dissipation, noise reduction, and impedance matching. The PSP400JB-240R is a Through Hole Resistor manufactured by Xicon, and is a common choice among many engineers for their circuit boards. This paper will discuss the application field and working principle of the PSP400JB-240R.

The PSP400JB-240R is a Through Hole Resistor that is primarily used for high-voltage applications, as well as power supply applications and sensing applications. Its primary purpose is to provide resistance in a circuit while dissipating energy. The PSP400JB-240R is an axial-lead resistor with an operating voltage up to 400V, an operating temperature from -55°C to +125°C, and a tolerance of +/- 5%.

The PSP400JB-240R is composed of a ceramic core, an electrolytic wirewound metal layer, and a solderable tinned copper-clad lead wire. The ceramic core provides mechanical support and insulation to the rest of the resistor. The electrolytic wirewound metal layer provides the resistor with its electrical resistance, while the tinned copper-clad lead wire allows for the connection of the PSP400JB-240R to other components of the circuit. The resistor also has a removable metal plate over the ceramic core, which helps protect the ceramic core from short-circuiting.

The working principle of the PSP400JB-240R is based on Ohm\'s law, which states that the current through a conductor is directly proportional to the potential difference across its ends. This means that the current through the PSP400JB-240R is proportional to the voltage across it. In other words, the higher the applied voltage, the higher the current that will flow through the resistor. At the same time, the higher the current, the more energy the resistor will dissipate, thus reducing the voltage across its ends.

The PSP400JB-240R is a reliable and efficient resistor that is commonly used in many applications. It is an ideal choice for applications such as power supply applications, high-voltage applications, and sensing applications. Moreover, its simple workings and design make it a convenient and cost-effective addition to any circuit design. Therefore, the PSP400JB-240R is a great option for anyone who is looking for an efficient and reliable resistor for their circuit board.
