Through Hole Resistors (THRs) are one of the most commonly used electronic components in industry today. They are widely used in applications ranging from consumer electronics to industrial machinery and heavy-duty machinery. The CCR218KKB is one of the most common THR configurations and is commonly used for DC voltage circuits as well as in high-frequency electronic circuits. It is a type of surface-mounting resistor that is composed of two metal leads, an insulating substrate, a terminal locking screw, and an internal resistor element. It is constructed from aluminum-nitride-based ceramic substrate to provide superior thermal resistance, high stability, and good electrical insulation.

The CCR218KKB is a way of denoting the physical size of the THR, and the C stands for "connector" while the R stands for "radial" and indicates the type of mounting. The 218 indicates the physical diameter of the part, which is 18mm, and the two K\'s indicate the resistance value of the part, which is 2000Ω (2KΩ). The B indicates the tolerance; in this case, it is ± 20%.

The CCR218KKB is typically used in applications where a small form factor is desired, allowing it to fit in tight spaces where other, larger THR configurations cannot. It is commonly used in DC voltage circuits, for example in power supply circuitry, where a small amount of resistance is needed to maintain correct voltage levels. It can also be used in high-frequency circuitry, such as in radio-frequency amplifiers and transmitters, where it can be used to modify signal levels.

The working principle of the CCR218KKB is relatively simple. When voltage is applied to the device, a current flows through the resistor element, producing heat, which in turn causes the resistance to increase. This increased resistance reduces the amount of current that can be drawn from the device, thus providing the desired voltage level. The amount of resistance provided by the device is determined by the size of the resistor element and the resistance value of the part, which is typically indicated by the two K\'s in the part number.

In summary, the CCR218KKB is a common THR configuration used in industry for applications requiring a small form factor and high-stability. It is commonly used in DC voltage circuits, as well as in high-frequency electronic circuits, where it can be used to modify signal levels. The working principle is simple; it employs an internal resistor element that increases in resistance when a voltage is applied, thus providing the desired voltage level.
