Through Hole Resistors are a kind of resistor used to mainly control the flow of current in different circuitry. The WLAR050FE is one of the most advanced types of through hole resistors. It is designed with a built-in temperature dependence function, which enables it to adjust the resistance value according to the temperature.The WLAR050FE is of small size which means that it can be used in smaller circuit design, thus providing more flexibility for engineers. With a low power rating of 0.25W, it is suitable for use in a range of applications, such as LED lighting, telecommunication, EMC filters, instrumentation, control systems and much more.The WLAR050FE is an NTC (Negative Temperature Coefficient) resistor, meaning that its resistance value will decrease when the temperature increases. This can be used to great effect in temperature control systems, as it provides accurate temperature readings and allows for precise control.The WLAR050FE is also capable of operating in the -55°C to +125°C temperature range, making it suitable for use in a variety of environments and applications. Its high temperature stability also ensures that it provides reliable readings in even extreme temperatures.The WLAR050FE\'s working principle is based on the basic principle of Resistance, Voltage and Current (R-V-I). The Voltage is applied across the resistor, which causes a current to flow through the circuit. The current is then measured using an ohmmeter in order to calculate the resistance of the resistor as well as the power dissipation. The WLAR050FE also utilises a thermistor to further increase its temperature measurement accuracy. A thermistor is a resistor which has a temperature-dependent resistance value. It is the main part of the WLAR050FE and is responsible for measuring and adjusting the resistance value according to the temperature.The resistance values provided by the WLAR050FE depend on several factors, such as the temperature, the integrated thermistor and the bias current. If the temperature increases, the resistance value of the thermistor will decrease, resulting in a lower resistance value of the entire circuit. Similarly, if the temperature drops, the resistance value of the thermistor increases, resulting in a higher resistance value of the entire circuit.In conclusion, the WLAR050FE is an advanced type of through hole resistor that is designed to be used in a variety of applications. Its working principle is based on the basic R-V-I principle, and it utilises a thermistor to further increase its temperature measurement accuracy. With its small size, low power rating, and high temperature stability, WLAR050FE provides reliable performance in a range of temperatures and applications.
