What are Through Hole Resistors and H840R2DYA?

Through hole resistors are an essential part of PCB design. They are used to reduce voltage and current fluctuations in electrical circuits and are made up of a resistor and a wire, which is usually copper or gold plated. The resistor is usually made of ceramic, metal and plastic and the wire is usually made of a metal alloy such as silver, gold, titanium or platinum.The H840R2DYA is a through hole resistor specifically designed for 220 ohms and below. It is a low power device with a low impedance of 2.2 ohms. It has a tolerance of 5%, a temperature coefficient of 100ppm/C and is rated at a maximum voltage of 25v.

Features and Benefits

The H840R2DYA offers several advantages over other through hole resistors. It has a very low impedance making it ideal for reducing voltage and current fluctuations. The low power design allows for reduced consumption and smaller components. The 5% tolerance allows for more accuracy and a longer life span. The temperature coefficient of 100ppm/C ensures that it can withstand up to 105°C with no adverse effect.

Application Field of H840R2DYA

The H840R2DYA can be used in a variety of applications. It is commonly used in consumer electronics such as TV’s, monitors and headphones. It can also be used in automotive electronics such as radios, amplifiers and motors. Medical devices such as thermometers, pacemakers and defibrillators also make use of this type of resistor.

Working Principle of H840R2DYA

The H840R2DYA functions by reducing the amount of current and voltage that flows through the circuit. This is done by providing resistance to the flow of electrons. This resistor works by providing a specific amount of resistance that you can set by adjusting the value of an external resistor. When the current flows through the resistor, it is converted into heat, which is then dissipated away from the circuit.

Conclusion

The H840R2DYA is a durable and reliable through hole resistor with an array of features and benefits. It is a low power device with a low impedance and a temperature coefficient of 100ppm/C. It can withstand up to 105°C with no adverse effect. The 5% tolerance allows for more accuracy and a longer life span. It is commonly used in consumer electronics, automotive electronics and medical devices.
