Introduction

Through hole resistors are a type of electronic component used in a variety of electronic circuits, primarily to resist the flow of current. The 83FR221 is a through hole resistor which is commonly used in many applications. This article will discuss the applications and working principles of the 83FR221.

Description

The 83FR221 is a through hole resistor and is classified as an axial-leaded resistor. As such, it is composed of two leads which extend from each side of the body and are designed to be inserted into a circuit board. Its construction is metal-film and its resistance is typically 221 ohms. It is given a power rating of 0.25W and a tolerance of +/-5%. The size of the resistor is 6.5mm long, 2.0mm wide, and 2.0mm thick.

Applications

The 83FR221 is a popular choice for a variety of applications, especially those where an accurate resistance is desired. It can be used in many different types of circuits including: power supplies, amplifiers, timing circuits, and voltage regulators. It is also often used in the protection of sensitive electronic components by reducing the flow of current. The 83FR221 is also commonly used as a part of radio frequency (RF) circuits, where its high accuracy is beneficial for maintaining the precise electrical characteristics of the RF signal.

Working Principle

The 83FR221 is an ohmic resistor. Therefore, its behavior is governed by Ohm’s law, which states that the current in a circuit is directly proportional to the voltage applied across it. The resistance value of the 83FR221 is determined by the size and composition of the metal film it is composed of. The metal film absorbs and stores energy, then releases it as electrical current. The shape of the resistor also plays a role in its functionality; the two leads of the resistor allow current to flow into and out of the device in a controlled manner.

Conclusion

The 83FR221 is a popular through hole resistor which is used in a variety of applications. It is an ohmic resistor, meaning its resistance is determined by the size and composition of its metal-film as well as its shape. This resistor is commonly used in power supplies, amplifiers, timing circuits, voltage regulators, and RF circuits. The accuracy of the 83FR221 makes it an ideal choice for many electronic circuits.
