100K Ohm Carbon Film Resistor 1/4W 5%

Carbon film resistor definition The carbon film resistor is a type of fixed resistor that uses carbon film to restrict the electric current to certain level. These types of resistors are widely used in the electronic circuits. Carbon film resistor construction The carbon film resistor is made by placing the carbon film or carbon layer on a ceramic substrate. The carbon film acts as the resistive material to the electric current. Hence, the carbon film blocks some amount of electric current. The ceramic substrate acts as the insulating material to the heat or electricity. Hence, the ceramic substrate does not allow heat through them. Therefore, these resistors can withstand at higher temperatures without any damage.
