As one of the essential components in electrical engineering, resistors are used in almost all electrical products and systems. Therefore, through hole resistors play an important role in electrical engineering. Among various through hole resistors, CBT25J68R is a kind of resistor that has been widely used in many applications.

CBT25J68R is a toroidal wirewound resistor that is designed specifically for applications that require high power dissipation. The resistor has a maximum power rating of 25 Watts and a tolerance of +/- 5%. Its main advantage is that it can dissipate higher power than other through hole resistors, that is, it has a built-in heat sink. Thus, it can handle large wattage applications with better stability and reliability.

The dimensions of the CBT25J68R are 46 mm x 25 mm x 8 mm, so it can be used in confined spaces. Its rated operating temperature is -55°C to +350°C and its maximum operating temperature is +400°C. The resistance of CBT25J68R can range from 0.68 Ohms to 68.0 Ohms depending on its specification.

The CBT25J68R resistor works by limiting current flow, reduced voltage, voltage division and so on. It is a static component, and as such it does not require power to operate. It is used in a variety of applications such as power electronics, electromechanical devices, motor control, power supply, amplifiers, and voltage protection control.

In the power electronics application, the CBT25J68R is widely used as a power resistor. It is most often used in high-power circuits such as large motors, electroplating rectifiers and Peltier coolers. Its large power capacity and standard size make it ideal for these applications. In voltage protection control, CBT25J68R is used as a current limiting device in circuits that are susceptible to overvoltage conditions.

For motor control applications, CBT25J68R is used as a load resistor, along with other power components, to provide the required current for motor control. Additionally, CBT25J68R is used as a current sensing resistor for current control devices in power supplies and amplifiers. Finally, it’s also used to limit the voltage in various circuits.

In terms of working principle, CBT25J68R is a current-limiting device. This means that it is designed to limit the amount of current that can flow through it. When a current is applied to the resistor, a voltage drop is generated across it. The amount of voltage drop depend on the amount of current applied and the resistance value of the resistor. This voltage drop is used to control current and provide protection.

In conclusion, CBT25J68R is a through-hole resistor that can handle large wattage applications. It is used in a variety of applications, such as power electronics, motor control, power supply, amplifiers and voltage protection control. It works by limiting the current flow and providing voltage regulation and protection. The CBT25J68R is an essential component for many applications, and it is a reliable and cost-effective solution for power dissipation needs.
