Through Hole Resistors are an essential class of electronic components in modern electronics. Millions of these devices are produced for use in a variety of applications, from micro-controllers to household appliances. The RL20S303JB14 is a type of through hole resistor that is capable of handling both very low and very high currents. This article will discuss its application field and working principle.

Application Field

The RL20S303JB14 is a robust through hole resistor designed for reliable operation over a wide range of temperatures. As such, it is suitable for use in a variety of applications. These include DC and AC circuits up to 500kHz, semiconductor circuits, and high-frequency automotive electronics. It is particularly recommended for use in motor drive and power supply circuits. It has also been used in applications requiring high pulse current handling, such as motor microcontrollers and solar panels.

The RL20S303JB14 is designed for use on printed circuit boards and meets all of the relevant industry standards, including IEC 60134-1 and IEC 60134-2. Additionally, it has excellent long-term reliability and resistance to thermal shock and dynamic vibration. This makes it well-suited for use in a wide range of applications.

Working Principle

The RL20S303JB14 is a through hole resistor with an aluminum oxide layer. This is the key component of the device, as it is what determines how it will behave in a circuit. The aluminum oxide layer ensures excellent heat dissipation, allowing it to handle large currents without significant power loss.

As with all resistors, the RL20S303JB14 works by creating a voltage drop across a resistor when a current is applied. The amount of voltage drop is determined by the resistance of the resistor, which is determined by the aluminum oxide layer. The RL20S303JB14 is designed to have a low resistance, allowing it to handle large currents without excessive voltage drop.

In addition to the aluminum oxide layer, the RL20S303JB14 also features an air gap between the terminals. This air gap helps to reduce the inductive reactance of the resistor, helping it to handle higher frequencies. Additionally, the air gap prevents arcing between the contacts, making it suitable for use in higher voltage circuits.

Conclusion

The RL20S303JB14 is a robust through hole resistor that offers excellent performance over a wide range of temperatures and frequencies. With its low resistance and high current handling capabilities, it is suitable for use in a variety of applications. Its aluminum oxide layer and air gap ensure excellent thermal dissipation and inductance characteristics, making it well-suited for use in high-frequency automotive electronics and other applications requiring reliable operation over a wide range of temperatures.
