Through Hole Resistors

Through Hole Resistors are simple electrical components that primarily help regulate the flow of electric current in an electronic circuit. They act as current limiters to prevent damage to other components in the circuit and determine, to some extent, the amount of voltage applied to specific areas of the circuit. Generally, through-hole resistors are rated according to traffic capacity and maximum working voltage, and these specifications typically determine their size and shape.

YR2B649K is a type of through-hole resistor and belongs to general resistors series. It is a carbon-based, single-terminal, discrete component that features a two-digit code and a power rating of 2 watts. It is composed of a ceramic substrate between two solder terminals. The two-digit code denotes the electrical resistance along with the tolerance rating, and the first two digits denote the resistance value in ohms.

The working principle of YR2B649K is based on ohm’s law, which states that the voltage across a resistor is directly proportional to the current passing through it. Thus, when a certain voltage is applied to the resistor, a certain amount of current passes through it. The resistance value of the resistor determines the amount of current that can pass through it and, thus, the voltage that’s applied to it. The higher the resistance value of the resistor, the more current it takes before the voltage is applied to it.

In terms of its applications, the YR2B649K is ideal for currents that are <=2A and voltages that range from 25 to 400 volts. It is mainly used in electronic circuits such as amplifiers, power supplies, light dimmers and various other circuits. It is also useful in many automotive and industrial applications. It is also ideal for use in television sets and radios.

To sum it up, YR2B649K is a type of through-hole resistor that is primarily used for regulating the flow of electric current in an electronic circuit. It has 2 watts of power rating and is often used in automotive and industrial applications. Additionally, it works on the principle of ohm’s law that states that the voltage across a resistor is directly proportional to the current passing through it. Thus, it is useful in many circuits and electronic devices for the restriction of current and adjustment of voltage.
