Through Hole Resistors (also known as through-hole mount resistors) are electronic components that are designed for use in hole-mounting assemblies. The OF202JE is a through hole resistor typically used in circuit boards and electronics products. It can be used in a variety of applications, including but not limited to power supply circuits, battery charging circuits, relay circuits, voltage regulators, and so on.

The OF202JE consists of a ceramic core encased in a flame-retardant epoxy coating. The material chosen for the core is a special ceramic compound that has a high electrical resistance and high temperature stability. The resistance of the OF202JE is determined by the size of its internal resistive element, which is typically made of nickel-chrome or copper-zinc alloy. The resistor is rated to a maximum power rating of 2 watts and to a temperature range of -55 °C to +105 °C.

One of the main benefits of the OF202JE is its ability to dissipate heat quickly. The resistor features an internal construction that enhances the rate of heat transfer, allowing the component to stay cooler and operate longer before needing to be replaced. Additionally, the design reduces the chances of mechanical failure, which makes the OF202JE a reliable and durable component.

The typical work principle of the OF202JE is based on Ohm’s law. According to this law, when the current flowing through the resistor is increased, the voltage drop across the resistor also increases. The voltage drop across the resistor is known as the resistance. The resistance value is determined by the surface area of the resistor and the type of material used in its construction. For example, a resistor with a larger surface area and made of an alloy material will have a higher resistance than a resistor with a smaller surface area and made of a ceramic material. The resistance value can also be varied by applying an additional voltage to the resistor.

The OF202JE can also be used as a voltage regulator. By connecting the resistor in series with a voltage source, it is possible to control the output voltage of the connection. This feature is particularly useful in applications such as powering an LED, or controlling the amount of power supplied to a motor.

As an example of a practical application of the OF202JE resistor, consider a circuit that controls the brightness of an LED. The resistor is placed in series with the LED and the voltage source, and the resistance value of the resistor is adjusted until the desired brightness is obtained. The LED will then receive the correct amount of voltage for the light output that you require.

The OF202JE has a wide range of practical applications and is a reliable and durable component. Its ability to dissipate heat quickly ensures that the component stays within its operating temperature range, and its adjustable resistance allows for easy control of the output voltage. Overall, the OF202JE resistor is an indispensable electronic component, which can be used to build a variety of circuit boards and electronics products.
