Through Hole ResistorsThrough hole resistors are components that are commonly used to limit and control the flow of electrical current in an electronic circuit. These resistors are installed on a circuit board by drilling holes in the board and inserting the appropriate resistors. They are then soldered into place to create an electrical connection.The WW2BB120R resistor is a through-hole type resistor manufactured by United Automotive. It is configured in a two-pin TO-18 package. The resistor is constructed from a ceramic tube filled with a special thermal compound to ensure optimal heat conduction. The two external pins provide circuit board connection and grounding.The WW2BB120R is a high-power, high-stability resistor designed for use in a wide variety of applications. It is rated at 120 ohms, with a maximum operating temperature of 175°C. The wattage rating for the WW2BB120R is 6.5 watts, which makes it well-suited for applications requiring high-level power dissipation.The main application field of the WW2BB120R is power supply and switch-mode power supplies (SMPS). It is used in these types of circuits to limit the current flowing through the circuit, which can help prevent damage from electrical surges. The resistor can also be used to control power output in circuits where the efficiency of a switching regulator is important, such as in switching LED drivers.The working principle of the WW2BB120R is fairly simple. It consists of an electrically resistive material, usually carbon, that can resist the flow of current. When current flows through the resistor, an opposing voltage is generated that is proportional to the amount of current flowing through the resistor. This opposing voltage is a characteristic of the resistor\'s resistance value. In other words, the greater the resistance value, the greater the opposing voltage produced.The thermal design of the resistor is also important for its operation. The resistor body is filled with a special thermal compound that helps to dissipate heat away from the component, allowing it to operate at higher temperatures without being damaged. The maximum operating temperature of the WW2BB120R is 175°C, and it is designed to handle up to 6.5 watts of power.The WW2BB120R is a robust, high-power, high-stability resistor that can be used in a variety of applications where reliable current limiting and power dissipation are required. It is well-suited for applications such as SMPS circuits, switching LED drivers, and voltage regulation circuits. Its thermal design ensures that it can handle higher temperatures without damage, making it an ideal choice for power-intensive applications.
