WCB15FBR330 Through Hole Resistors: Application Field and Working Principle

When it comes to components that control and regulate electrical current in electronic circuits, resistors are an indispensable part of every system. Designed to control the flow of current in a circuit, these components can be either fixed or variable, depending on the required performace. Among the various types of resistors available in the market, through hole resistors, like the WCB15FBR330 model, are particularly popular due to their reliability, accuracy and ease of use.

What is a Through Hole Resistor?

A through hole resistor, or a through-hole component, is a cylindrical object used to control electrical current in an electronic device and is usually made of an alloy with a high resistivity such as nickel-cobalt, which is then coated in insulating material. While this type of resistor was traditionally larger than other resistor types, today’s through hole resistors are much smaller and can fit in the tightest of spaces.

Application Field of Through Hole Resistors

Through hole resistors can be found in virtually any circuit requiring current regulation, and depending on the required performance, they can be used as either volt-drop or time-delay elements. For instance, one of the most common uses of through hole resistors is in audio and video equipment, such as amplifiers, televisions and receivers. Another application is in medical equipment, where the resistor\'s high accuracy and quality is essential to ensure the equipment\'s reliability.

The WCB15FBR330 resistor from Yageo, or the RC ‘small series’ resistor family, is a great example of a through-hole resistor used in a variety of applications, ranging from industrial control to telecommunications. This resistor can handle up to 1W and can withstand temperatures up to 250°C. It’s made from a robust alloy such as nickel-chrome or manganese-copper, and features a small footprint, making it perfect for tight spaces and small areas.

Working Principle of Through Hole Resistors

When a current passes through a resistor, it experiences a reduced current and voltage drop, due to the resistance material in the resistor. This drop in voltage causes heat to be generated, which is dissipated through the coil of the resistor, thus protecting the circuit from dangerous overloads. A benefit of through hole resistors lies in the fact that the resistance of a through hole resistor can be easily adjusted. Inside the cylinder, which is filled with a resistive material, is a cylindrical contact that can slide up and down, changing the amount of resistance that the component offers.

Conclusion

Components like the WCB15FBR330 through hole resistor are an essential part of any circuit application, whether it’s audio equipment, medical devices or industrial machinery. With its small size, robust construction and adjustable resistance, it can provide great performance and reliability for many years to come.

Whether you need a simple voltage drop resistor or a more precise, adjustable option for your project, resistors like Yageo’s RC ‘small series’ can provide the perfect solution for your needs.
