WW3AFT47R0 application field and working principleThrough Hole Resistors are very widespread and form an integral part of many simple electronic devices such as radios, television sets, toys, computers, and more. In some cases, high-power resistors may be too large for a complete device or need to be connected to other components that cannot handle the large power demands required of the resistor. In such cases, Through Hole Resistors such as the WW3AFT47R0 can be used. These resistors have a higher current capacity than most other types of resistors, making them suitable for use in more demanding applications where temperatures can reach up to 200°C and power ratings of up to 7 watts.The WW3AFT47R0 Through Hole Resistor is an economical and reliable component for most electric or electronic applications. The resistor is coated in a ruggedized epoxy coating, and its contacts are high-temperature resistant, thus making it suitable for extreme environments. Its terminals are triple-clad in Nickel-Chromium alloy and have a rated life of 25,000 hours at 80°C. The resistor features low-temperature coefficient (LTC) resistance and is RoHS- and REACH-compliant.The working principle of the WW3AFT47R0 is quite straightforward. Essentially, the resistor uses electrical resistance to reduce the flow of current. It does so by limiting the flow of electrons through a material, usually an organic compound such as carbon, which is usually sandwiched between two sets of metal contacts. By adjusting the distance between the two contacts, the current is forced to travel a greater distance, thus reducing the flow of electrons. In this way, the resistance can be adjusted to meet the desired power output and current carrying capacity of the device.In conclusion, the WW3AFT47R0 Through Hole Resistor is a reliable and cost-effective component which can be used in many electronic devices and applications. Its high current capacity, RoHS- and REACH-compliance, and robust construction make it ideal for use in demanding environments where temperatures can reach up to 200°C and power ratings of up to 7 watts. With its well-documented working principle and high reliability and endurance, it is no wonder why the WW3AFT47R0 is such a popular choice across industries.
