The H81K47BCA series of through hole resistors is a general-purpose component used for a variety of applications. These resistors are designed for use in both consumer and industrial electronics. The H81K47BCA is a valued component when building any electronic device as it offers high reliability, high stability, and low cost.

The H81K47BCA is a carbon-film through hole resistor, a type of resistor which has been widely used for applications such as power supplies, motors, inverters, switching circuits, and low power DC circuits. This resistor is designed with four contact holes for mounting to a PCB and features a power rating of 1 watt at an operating temperature up to 125°C. The H81K47BCA is available in multiple resistance values and tolerances ranging from 10 ohms up to 10 megohms with tolerances of ±1%, ±5%, and ±10%. The lead wires are 100 mm long and made of Tin plated copper wire.

The H81K47BCA uses carbon film to provide resistance in its construction. This is achieved by depositing a thin film of carbon material onto a resistor body. This material has a known resistance per unit length so the resistor’s resistance is determined by the length of the carbon film on the body of the resistor. The size of the resistor is kept as small as possible for space saving while still having the power rating required for the application. It has a grey body made from a phenolic material and has a solderable finish.

The working principle of the H81K47BCA through hole resistor is fairly simple. When a voltage is applied, a current flows through the resistor body and out the contact holes. The resistor works by introducing resistance to the circuit, thus limiting the current that passes through it. This allows the current to be regulated and thus voltage controlled. The resistance value that can be provided by the resistor depends on the size of the resistor and the amount of carbon film deposited on the body.

The H81K47BCA through hole resistor is part of a group of components known as passives which are essential for circuit design and control. Resistors are used in many applications such as in motors to control the speed, in communications to filter out unwanted frequencies, or in audio circuits to adjust the volume. They are also used in power supplies to regulate the voltage and current, and they are used in timing circuits to precisely control the timing of an operation.

In short, the H81K47BCA through hole resistor is an invaluable part of any electronic system. They are highly reliable, stable, and cost-effective. They have many applications in industry and consumer electronics. And they provide the necessary resistance to help regulate and control the power and voltage in the device in which they are used.
