B<div><strong>Through Hole Resistors</strong></div><div></div><div>A through hole resistor is an electronic component consisting of a metal rod, usually metal, copper, or ceramic, that is mounted in a hole or bore through a board for cold soldering. Through hole resistors are commonly used for voltage divider circuits, temperature sensing, current sensing, power control and other basic electrical protection purposes. The most widely used type of through hole resistors is the WW3AJT220R.</div><div></div><div><strong>WW3AJT220R application field</strong></div><div>The WW3AJT220R is a type of through hole resistor and it is suitable for a wide variety of applications due to its low-profile design and passive design which helps reduce costs and maximize efficiency. It is typically used in power control and temperature sensing applications such as voltage divider circuits and current sensing applications. The WW3AJT220R can also be used in DC-DC converters, motor controllers, current sensors, and other applications where a compact, reliable through hole resistor is needed.</div><div><br /></div><div><strong>WW3AJT220R Working Principle</strong></div><div>The WW3AJT220R is a through hole resistor and is based on the principle of resistance, which is the opposition of an electrical current to the flow of electrons through a circuit. A resistor works by converting a part of the electrical energy passing through it into heat energy, which is released as a resistor is heated by the voltage flowing through it. The higher the resistance, the more voltage drop across the electrical circuit, and the more heat heat generated.</div><div><br /></div><div>The WW3AJT220R is constructed by arranging a metal rod into a thin cartridge with a contact on one end and the other end terminated with a cylindrical-shaped endcap. The resistor element is then wire wound onto the metal rod, with a water-soluble insulation such as silver or nickel-plated copper wire. The endcaps are then sealed to the board with a pressure fit, which helps to create a reliable electrical connection between the resistor element and the board.</div><div><br /></div><div>The WW3AJT220R is designed for use in low-profile applications such as motor controllers, current sensors, and temperature controllers. This type of through hole resistor offers a high power rating of 220 watts and a low ESR rating of 0.5 Ohms. The low ESR rating makes this resistor an excellent choice for high-power applications, as it can more easily dissipate heat and maintain stability.</div><div><br /></div><div>The WW3AJT220R features a very small size and a robust design. The resistor is able to withstand temperatures up to 125°C and can operate in a wide range of frequencies up to 33 MHz. The resistor is also RoHS compliant, making it an environment-friendly choice for a variety of applications.</div><div><br /></div><div>In conclusion, the WW3AJT220R is a type of through hole resistor that is perfect for a wide range of applications due to its design and ability to withstand high temperatures and handle high power. Its low ESR rating and RoHS compliance make it an ideal choice for a variety of electrical protection and temperature sensing applications.</div>
