CPW052K200KE31 Resistors

Through hole resistors are among the most commonly used components in electrical systems, and the CPW052K200KE31 resistor is no exception. Its uses range from basic power applications to more critical ones where high precision is required. The CPW052K200KE31 is classified as an EWR-type resistor, meaning it is a combination of a wirewound resistor and a thick film resistor. Wirewound resistors are made by winding metal wire around a core. Thick film resistor elements are also called ceramic resistors–because they are manufactured with a thick film of glass-ceramic material. Additionally, the CPW052K200KE31 is a non-inductive resistor, meaning it has low reactance–which makes it suitable for power-supply circuits with very high-speed switching pulses.

The traditional application of the CPW052K200KE31 is in power supplies, where its low reactance is important for the efficient operation of power-supply circuits. Its highly stable rating and its excellent thermal stability make it an excellent choice for load protection and overvoltage protection applications. Other uses for the CPW052K200KE31 include high-speed switching circuits, LCD backlighting, resistive bridge circuits, and for DC-DC converters, AC-DC converters, switching regulators, and other applications where precision and stability are essential.

The working principle of the CPW052K200KE31 is simple yet effective. It uses a combination of wirewound resistors and thick film resistor elements to accurately control the flow of current. In a typical setup, a wirewound resistor is connected between two points on the circuit board while the thick film element is connected between the negative end of the wirewound component and the circuit ground. This arrangement creates an electrical resistance that is not affected by temperature, humidity, or other environmental factors. This ensures that the output of the resistor remains accurate and reliable under all operating conditions.

The CPW052K200KE31 is a versatile through hole resistor with a wide range of uses in power supplies and other precision electrical systems. It combines a wirewound resistor and a thick film resistor element to create a highly stable, non-inductive resistor with excellent thermal stability. This makes it an excellent choice for load protection, voltage regulation, overvoltage protection, and high-speed switching circuits. It is also a useful tool in designing DC-DC converters, AC-DC converters, and switching regulators.
