Through Hole Resistors

Through hole resistors refer to resistors with wires or leads extending from both ends of the resistor element. The lead is inserted into the printed circuit board (PCB) and soldered there to provide the desired electrical connection, often at the cost of added size and complexity of installation. The most popular type of through-hole resistor is the Axial Resistor, which has the resistance element sandwiched between two metal end caps with two wire leads extending from the caps in opposite directions.

CW0108R000KE12\'s application field mainly includes automotive, telecommunications and gaming industry where excellent performance and precision is required. In addition, its compact size and excellent power rating also make it suitable for use in high-speed digital circuits.

Working Principle

CW0108R000KE12 is a through-hole resistor, so it works according to the principle of resistive materials. This type of resistor utilizes the correct number of coils of either a metallic or oxide coating on a ceramic or glass core. As current flows through the resistor, it encounters the resistivity of the coils, which converts some of the power within the current to heat. This heat causes the resistance of the resistor to increase which, in turn, decreases the amount of current flowing.

By carefully controlling the number of copper coils wrapped around the core and the thickness of the oxide coating, it\'s possible to create a resistor with a specific resistance value. The resistance value is represented by the number stamped on the resistor\'s metal case, or by the resistor color code. The resistance value can be determined by measuring the voltage drop across the resistor with an ohmmeter.

The CW0108R000KE12 allows high-speed operation without the risk of high voltage breakdown. It has a very low temperature coefficient, providing the user a wide operating temperature range of -55°C to +125°C.
