Through hole resistors, commonly referred to as THRs, are a type of fixed resistor Mounted on the printed circuit board (PCB) using a two or three part terminal assembly. Examples of a THR include glass-encapsulated axial resistors, bulb-in-line resistors, and radial-lead resistors. Due to its life-long stability and dependability, high and low resistance values, and wide range of temperature coefficients, it is suitable for multiple application fields, such as general electronics, appliances, automotive, and telecom. Specifically, FMP200FBE52-143R is a THR. This paper discusses its application field and working principle.

FMP200FBE52-143R is a high-power chip resistor, mainly used for applications such as automotive, industrial, and instrumentation. Its rated power is 200mW and it has a resistance range of 1 to 10 k Ohm, which makes it suitable for high power circuits. It has three terminals, with two of them soldered directly to the PCB and one of them connected to a ground plane, providing excellent thermal and electrical performance and stability.

In terms of its working principle, FMP200FBE52-143R is based on the principle of Ohm\'s law, which states that when the voltage applied across a conductor is increased, the current flowing through the conductor increases proportionately. This is due to the fact that the resistance of a conductor is directly proportional to its cross-sectional area and inversely proportional to its length. Thus, when voltage is applied to a THR, its resistance reduces due to the increase in cross-sectional area; hence, the current increases. This increase in current is used to power the device, or to power other devices connected to it.

FMP200FBE52-143R also has a high linearity, which is important in applications that require precise control of voltage or current. This is achieved by its large cross-sectional area, which ensures that there is minimal difference between the actual resistance and the expected resistance, thus ensuring precise control. Furthermore, it has a wide operating temperature range of -55°C to +125°C, which makes it suitable for most applications.

Additionally, because FMP200FBE52-143R is an electrically-isolated THR, it offers protection against voltage surges and sudden increases in current, thus preventing damage to the connected circuit. Additionally, it features low inductance characteristics, which reduces the noise in high-speed circuit system. In addition, its thick terminal cover helps protect the contacts from environmental contamination.

In conclusion, FMP200FBE52-143R is a THR with excellent characteristics, and thus can be used in multiple application fields. It is based on Ohm\'s law, and thus has a high linearity and low inductance characteristics, when the voltage applied across it is increased, its resistance reduces due to the increase in cross-sectional area; hence, the current increases; this increase is used to power other devices connected to it. Finally, its thick terminal cover helps protect the contacts from environmental contamination.
