Through hole resistors offer an effective and reliable way to limit current within an electric circuit in order to protect other components from overload. They enable engineers to limit current to a provided value or to divide the voltage within an electrical system. This type of resistor includes FMP200FRF52-21R, which is a long-term stable fin-type compact resistor. It has a small size and can be placed accurately in the space, providing high stability and output precisely.

Applications of the FMP200FRF52-21R include power supplies, circuit protection, linear regulators, motor control, DC/DC converters, user applications, and many others. It is usually used as a medium-power rated non-flammable stability resistor with low thermal EMF and low thermal resistance. It offers high-stability and low-voltage tolerance, as well as features an excellent pulse response. It is also an effective way to limit current for surges, overloads, and overvoltages in the circuit. Additionally, the FMP200FRF52-21R can be used to resist constant voltage in the low-frequency circuit.

The working principle of the FMP200FRF52-21R is based on the Ohm\'s law, which states that the voltage across a constant resistance is directly proportional to the current through it. This means that when the amount of current passing through the resistor is increased, its voltage is also increased, leading to higher power dissipation. The power dissipation of this resistor is normally kept around 1/6 of its rated power in order to extend its lifetime and improve performance. The temperature of the resistor is also highly dependent on power dissipation – if it is heated for a long period of time, it may degrade and its performance can become erratic.

The FMP200FRF52-21R is typically composed of a resistive element, which is made of a metal alloy or a combination of filamentary materials. This resistive element is usually connected to terminals that are made of copper or aluminum. The terminals are then mounted on a ceramic or organic substrate. The resistor is then protected with a coating and sealed with insulating material, typically a polyester resin. As a result, this resistor can continue to perform stably even under extreme conditions, i.e. shock, vibration, temperature cycling, and other harsh environment situations.
