FMF200FTF73-100K

Through Hole Resistors

Through-hole resistors are one of the most common types of resistors found on electronics. The FMF200FTF73-100K is a through-hole resistor commonly used in the electronics industry.

Application Field

FMF200FTF73-100K is a type of through-hole resistor, which is applied in almost all electronic applications. It commonly finds applications in numerous circuits including power distribution, RF circuits, DC/DC converter, regulator-based circuits, switching power supplies, and many more. As it is a purely linear, fixed-value resistor, it finds a vast application in almost any type of circuit that requires a fixed resistor.

Design

The FMF200FTF73-100K is designed as a through-hole type resistor, and hence requires a mounting hole to be drilled in the PCB assembly for its electrical connections. Its dimensions are as follows: 8.2 x 4.75 mm overall size, 6.1 mm lead spacing. It is a conventional leaded resistor with two tin-plated copper terminals (leads) of nickel-plated copper sleeve.

Features

The FMF200FTF73-100K comprises of a carbon element with a flame-retardant coating, generally made of polyester material. It is designed to operate in temperatures ranging from -55°C to +155°C, and it has a power rating of 200mW. It has a three-digit code stamped on the resistor body, providing the resistance information in ohms. The three-number code generally denotes the resistance of the resistor, with the first number representing the first significant figure, the second number representing the second significant figure, and the third number representing the number of zeroes.

Working Principle

The working principle of the FMF200FTF73-100K is based on the resistive element found inside the resistor - a carbon element coated with a flame retardant material. When a voltage is applied across both leads of the resistor, an electric current is then passed through the resistor, which then produces a power dissipation. This power dissipation is dependent on the resistance level of the resistor, with higher resistance levels producing more power dissipation. As the resistance is fixed, the amount of power dissipation and the nature of the current will remain constant. As a result, by using multiple resistors of different resistance levels, it is possible to form different combinations of resistors to form different circuits such as power supplies, amplifier configurations, or switchmode power supplies.

Conclusion

The FMF200FTF73-100K is a widely used through-hole resistor, suitable for many different types of electronic applications. It can be used to construct a multitude of different circuits and can withstand temperatures between -55°C to +155°C. Its design gives it a fixed-value resistance, meaning that its current and power dissipation will remain the same.
