Through Hole Resistors (H861K9DCA)

Through Hole Resistors are used in a variety of applications, from circuit boards to motors, amps, and speakers. The H861K9DCA is just one type of through-hole resistor that is available for designs of various power and performance specifications.

This component has a higher power rating compared to some other through-hole resistors, being able to withstand up to 20 Watts of continuous power. It is also less likely to suffer damage due to vibration or movement, making it an ideal choice for applications such as motor control and automotive electronics.

The H861K9DCA Through Hole Resistor has a unique construction, which has a large hollow ceramic (aluminum oxide) body and a metalized center electrode. This construction creates a higher power dissipation capability when compared to other through-hole resistors. It also minimizes the number of components needed in a design and can act as a thermal breaker to help limit the current. The H861K9DCA Through Hole Resistor is typically used in circuits where carries up to 20 Watts of power, such as audio amplifiers, automobiles, and electronic ignition controls.

In addition to the higher power rating, the H861K9DCA also features a low resistance value and a good TCR (Temperature Coefficient of Resistance). Its resistance range is 0.260 Ω to 3.3 kΩ and its E-24 (±10%) tolerances are as detailed in the datasheet.

As a through hole resistor, the H861K9DCA is designed to be soldered into a through-hole PCB, making it a popular choice for industrial and high power applications. It’s also a cost-effective solution because you don’t need to buy additional wire for the connection, as the H861K9DCA consist of a single-piece construction.

The working principle of the H861K9DCA is based on Ohm\'s law, the physics principle describing the relationship between current, voltage, and resistance. Ohm\'s law states that the current I flowing through a resistor R is directly proportional to the voltage V and can be found using the equation I=V/R.

The voltage across a resistor, V, is equal to the current I multiplied by the resistor\'s resistance, R. The current in the resistor is determined by Ohm\'s law, which states that the current is proportional to the voltage in the resistor.The power dissipated in a resistor is given by the equation P=VI, which means the total power dissipation will be equal to the product of the voltage across and the current through the resistor.

Finally, the H861K9DCA Through Hole Resistor has a high thermal resistance and a low voltage coefficient. Its thermal resistance varies with power rating and can range from only 0.80 C/W at 5 Watts to 1.75 C/W at 20 Watts. Its voltage coefficient is also low, which is important in applications such as electronic valves, variable speed drives, motors and transformers.

In summary, the H861K9DCA Through Hole Resistor is a highly reliable component that is well suited for a wide range of industrial and high power applications. It has a high power rating, a low resistance value, and a low voltage coefficient. As a through hole component, it is easy to install onto your circuit board and its unique construction minimizes the number of components needed in your design. Plus, its high thermal resistance and good TCR make it well suited for high-temperature applications.
