Through Hole Resistors

A through hole resistor is an electronic component used to measure, control, or regulate electrical signals in various electronic circuits. Through hole resistors come in a variety of forms, shapes, and types, and each type has its own unique characteristics such as resistance, voltage, and current ratings. The most common type of through hole resistor is the H844R2DCA.

H844R2DCA Application Field and Working Principle

The H844R2DCA is a through hole thick film resistor with a maximum power rating of 0.250 watts. It is designed for general purpose use in high frequency circuit applications, and can tolerate up to 250 volts. The H844R2DCA is constructed of thick film resistive elements and multiple layers of epoxy coating for maximum durability. The resistor has a low temperature coefficient of around 2%, meaning it can maintain consistent resistance even when exposed to extreme temperature fluctuations.The H844R2DCA is designed for use in a variety of circuit needs, from low-level signal conditioning applications to high-voltage and high-current applications. It is often used in power supplies, amplifiers, audio circuits, and industrial control equipment. The resistor\'s low temperature coefficient ensures that the signal being sent remains consistent even when ambient temperatures change.The working principle of the H844R2DCA is simple: electrical current is forced to pass through the resistor, which then converts some of that electrical energy into heat energy. This heat energy is dissipated away from the resistor, reducing the amount of electrical energy in the circuit. The amount of resistance is determined by the thickness of the resistor\'s film and the material used in its construction, and can range from a few ohms to many megaohms.The H844R2DCA is an innovative yet simple type of resistor that is highly reliable and accurate, making it ideal for a wide variety of applications. Its temperature coefficient and low-noise performance make it particularly well-suited for audio-related applications, while its durability and compact size are useful for industrial settings. The H844R2DCA is also often used in medical equipment, due to its accuracy and reliability.
