Through hole resistors are a type of electrical component used to decrease the flow of electric current by creating an electrical resistance, hence the name resistors. The WCB10JBR300 is a through hole resistor specifically designed for surface mount applications. It has a small size and a low profile shape for easy fitting, and has both axial and radial lead connections. Despite its small size, it provides a noise-free performance and high reliability.

The WCB10JBR300 is typically used in communication circuit applications, EMI/RFI filters, and for general purpose resistors. It can also be used for switching applications such as power supplies, regulators, and motor control. Additionally, it can be employed in inverters, amplifiers, and other related electronics equipment.

The WCB10JBR300 has a high insulation voltage of 500VAC and its insulation resistance is a minimum of 1000MΩ. It is designed to operate in temperatures ranging from -55°C to +105°C, and humidity from 20%RH to 85%RH. Its power dissipation is 150mW. The resistor is rated for a composition of 5%-10% tolerance, and a maximum overload voltage of 500V.

The working principle behind the WCB10JBR300 is based on a simple, yet effective design. The resistor consists of a semiconductor material called a resistor chip, and two side contacts called “terminals”. The resistor chip is made up of a semiconductor material, such as carbon or polyimide, which acts as the primary resistance element. In general, the relationship between current and voltage can be expressed as V=IR, where V is voltage, I is current, and R is resistance. Thus, when the voltage across the resistor chip is varied, the current flowing through it will also change proportionally.

When the circuit is closed, the current will flow through the resistor chip from one terminal to the other, and the voltage drop is determined by the resistance value of the resistor chip. Also, as the current flows through the resistor chip, Joule heating will occur, producing a temperature rise in the resistor. This temperature rise is related to the amount of power dissipated, or the wattage of the resistor.

In conclusion, the WCB10JBR300 is a through hole resistor used for surface mount applications, and is suitable for a wide range of circuit applications. Its simple design is based on the working principle of varying the voltage and current flowing through the resistor chip to create an electrical resistance. With its low profile shape and small size, it provides a noise-free performance and high reliability.
