The OF821JE is a through hole resistor with many uses in different types of electrical and electronic hardware. The resistor is a passive two-terminal electronic component that offers electrical resistance as a form of electrical impedance to the flow of an electric current through it. It is used in different electrical circuits to regulate and control the current flow, voltage levels, and other factors. The component is usually made of a non-magnetic material, such as carbon, metal, or ceramic, and is available in various sizes and shapes.

OF821JE is a metal film resistor that provides a precision resistor with low noise characteristics. It is designed to meet the requirements of low noise applications, including audio projects. The resistor offers excellent stability, low thermal emissivity, and good temperature coefficient of resistance (TCR). The OF821JE is rated in the range of 0.5 to 4.5 W, with current ratings of 0.1 to 2 A. The resistor is ideally suited for use in precision circuitry, as it has low DC resistance. It is also suitable for pulse-width modulation applications, due to its low parasitic capacitance.

The OF821JE works on the principle of Ohm\'s Law. This law states that the current flowing through a resistor is directly proportional to the voltage applied to it, and inversely proportional to its resistance. In other words, the resistor\'s resistance determines how much current passes through it, when the same voltage is applied to the resistor. The reason for this is that the higher the resistance of the resistor, the more it restricts the movement of electrons through it. On the other hand, the lower the resistance of the resistor, the lesser it restricts the flow of electrons.

The application field of OF821JE includes power supply, amplifier, signal conditioner, audio, and filtering circuits. It is also used in automotive circuits, medical electronics, telecommunications and instrumentation. The resistor is commonly used in various power supplies, audio amplifiers, and other control applications, allowing user-configurable resistance. It is also used in various audio circuits, such as equalizers and amplifiers, to attenuate audio signals. As the resistor provides low current, it is suitable for circuit protection. The OF821JE is also used in scanners, digital cameras, and other imaging equipment, as well as in various motor control appliances.

The OF821JE is a reliable, accurate, and cost effective resistor, which is widely used in different types of applications. It is a through hole resistor that offers excellent electrical characteristics, good temperature coefficient of resistance, and low noise characteristics. The resistor is well suited to work in high temperature environments, making it an ideal choice for many different types of applications.
