FMP300FTE73-243R

Through Hole Resistors are a type of electrical component designed to restrict the flow of electricity through an electric circuit. The FMP300FTE73-243R resistor is a through hole resistor specifically designed for power applications.

Application Field

The FMP300FTE73-243R is a through hole resistor designed for power applications, including switching power supplies, light drivers and motor drivers. This specific type of resistor is constructed using a ceramic body and a metal cap. It has an EIAJ dielectric grade and also has an insulation resistance in excess of 100 Mohm at 500 volts. It also has a power rating of 0.1 watts and can handle voltages up to 10kV. It features an open circuit and a closed circuit protection.

This resistor can be used in a variety of applications, such as industrial control systems, networking and telecommunications equipment, automotive systems and consumer electronics. It can also be used in appliance control circuits, LED lighting, battery chargers and motor controllers.

Working Principle

The working principle of this resistor is the same as for any other resistor. When electric current flows through the resistor, some of the energy is lost as heat, which is dissipated through the ceramic body. This decrease in electrical energy is equal to the resistance of the resistor. The resistance of the FMP300FTE73-243R is very precise and can be adjusted to a specific value to meet any applications needs.

The resistor also features a thermal shutdown feature. This ensures that the resistor does not overheat and become damaged due to excessive current passing through it. This is done by a thermistor that is just below the metal cap of the resistor. If the ambient temperature of the resistor rises beyond a certain level, the thermistor will trigger and disconnect the power to the resistor.

The FMP300FTE73-243R is an excellent choice for power applications because of its high power rating and its ability to dissipate the heat generated by the current passing through it. It also features an open circuit and a closed circuit protection, which helps to ensure that the resistor does not become damaged due to an over current or an over voltage. This makes it a reliable choice for power applications.
