Through-hole resistors, sometimes called leaded resistors, have traditional cylindrical metal cases and wire leads. The resistance element is usually made of ceramic but other materials such as carbon are sometimes used. The wires or leads protrude from the sides of the resistor body and are commonly bent into “leads” or “hooks” for easier mounting in a circuit board. One of the most popular through-hole resistors is the ER74R05GT resistor.

The ER74R05GT resistor is a leaded component, which is specifically designed for use in high-frequency applications, and can also be used in telecoms and other applications that require active components such as capacitors, inductors, and transistors. The ER74R05GT resistor uses a small ceramic body filled with an oxidized, high-conductivity material. This ensures that the resistor absorbs minimal heat and is highly resistant to both mechanical and thermal stresses.

The size of the resistor is also designed to be convenient and space-saving. The leads are extended from the sides of the cylinder and bent at a 90-degree angle to ensure easy insertion into through-hole circuitry. The resistor is coated with a layer of epoxy to protect against shorting and further increase its mechanical strength. The ER74R05GT resistor is designed to handle currents of up to 5A with a maximum dissipation of 1.0W.

The working principle of the ER74R05GT resistor is based on its ceramic encapsulation. This encapsulating material serves to reduce the circuit losses and prevent the voltage and current from dropping. The ceramic also helps to reduce leakage currents. The resistor typically has a nominal resistance of 200 Ohms, although its resistance can vary depending on the application. The resistance is also affected by temperature, meaning that the resistor can be used in temperature-insensitive circuits.

In summary, the ER74R05GT resistor is a popular through-hole resistor designed for use in high-frequency applications. The resistor uses a small ceramic body filled with an oxidized, high-conductivity material and is designed to handle currents of up to 5A with a maximum dissipation of 1.0W. The resistor also has a nominal resistance of 200 Ohms, although its resistance can vary depending on the application. The ceramic encapsulation of the resistor serves to reduce the circuit losses and prevent the voltage and current from dropping.
