Through Hole Resistors

Through hole resistors are an important type of electrical component that is widely used in various industries today. They are designed to provide electrical resistance to either reduce or limit the current in a circuit. A typical through-hole resistor is composed of metal-oxide layers or an element such as carbon or metal. These resistors are usually created with a circular or square shaped body and can be made in a variety of sizes and shapes.

B20J200 Application Field and Working Principle

The B20J200 through hole resistor is one of the most popular resistors used in a wide variety of applications. It is often found in high power electrical applications, such as in vehicle wiring, domestic appliances and communication systems. These resistors provide low equivalent series resistance (ESR) at high frequencies, and are generally used as current limiters or voltage absorption devices. The structure of the B20J200 consists of a ceramic cylinder body with the added metal electrodes.

As the resistor is designed for high-frequency RF signals, the metal electrodes provide a low inductance path for the signals. The ceramic body also acts as an insulator, isolating the signals from the external environment. The ceramic body has a very low dielectric constant, which means that it does not absorb much energy when signals pass through it. As a result, the ceramic resistor can block high frequency noise without causing distortion.

The working principle of the B20J200 is relatively simple. When a current passes through the ceramic body, it creates a magnetic field surrounding it, which creates a voltage drop. This voltage drop is proportional to the current passing through the resistor, so this type of resistor is called a “constant current” resistor. The B20J200 also has a certain power rating, meaning it is able to handle a certain amount of energy before it fails.

The B20J200 through hole resistor is a great choice for applications that require a high power level, but a low voltage drop, such as in power supplies and amplifiers. It also offers superior noise immunity, making it great for high frequency noise, such as in wireless applications. As the B20J200 is constructed from a ceramic body, it also offers excellent thermal and mechanical durability, making it highly reliable in demanding applications.

Conclusion

The B20J200 through hole resistor is a reliable and efficient choice for many applications. It is designed to provide low equivalent series resistance (ESR) at high frequencies, and offers low voltage drop and superior noise immunity. It is also constructed from a ceramic body, making it thermally and mechanically robust. Thanks to its high power rating, it is suitable for a wide range of applications, from power supplies and amplifiers to wireless applications.
