The CBT25J680K is a type of through hole resistor. Generally speaking, these types of resistors are fixed component devices that have two contacts, one of them being an adjustable contact, while the other one is a grounded contact. They provide resistance to electric current flowing through them and are designed to limit current, divide voltages, and dampen electronic signals.

The CBT25J680K targets applications such as general purpose AC or DC motor control, power adjustment or heaters. This through-hole resistor has a power rating of 680K and is also rated for a voltage drop of 25. It is capable of dissipating thermal power up to 8W with an operating temperature range of -55°C to 155°C.

The working principle of the CBT25J680K is based on the fact that electric current flowing through the device has to meet certain immersement, such as high resistance. A through-hole resistor made up of a combination of materials, usually graphite and resistive metal, works by acting as a barrier which restricts the current flow. This type of resistor works by utilizing Ohm\'s law, which states that voltage is equal to the current times the resistance.

Additionally, the CBT25J680K also follows the Joule effect, which states that energy is dissipated as heat when charges flow through a conductor with some resistance. This type of resistor has a rectifier which helps to reduce the current induced by the flow of current. The resistive element is located between the two contacts, which helps to reduce the voltage or current.

The CBT25J680K is designed to have good thermal stability and noise suppression. Its self-heating feature ensures that the resistor is not damaged by overheating. Moreover, it exhibits temperature coefficients of -100 PPM/°C, which provides additional protection against voltage or current variations caused by temperature changes.

In summary, the CBT25J680K is a through-hole resistor that targets applications such as general purpose AC or DC motor control and heaters. Its working principle is based on the fact that current flowing through the device meets certain immersement, such as high resistance. In addition, the CBT25J680K also follows the Joule effect and has a rectifier which helps to reduce the current induced by the flow of current. Finally, its self-heating feature and temperature coefficients of -100 PPM/°C provide additional protection against voltage or current variations caused by temperature changes.
