Through Hole Resistors

Through hole resistors are an electrical component consisting of a resistive element, terminals, and sometimes a packing element. These components can be used in a variety of electrical applications where a resistor is required. The H821K5BYA is a popular example of a through-hole resistor.

H821K5BYA Application Field and Working Principle

The H821K5BYA is a carbon film (sometimes called thick film) through-hole resistor. It is a popular choice among engineers because of its resistance range, high power rating, and long life. It is a 5 watt resistor with a maximum power dissipation of 3 watts. Its resistance range is from 1K ohms to 10K ohms and its tolerance is 5%.

The H821K5BYA is usually used in low-frequency applications. Typical applications include power conditioning circuits, audio amplifier stages, and power supplies. It is also used in filtering and radio frequency applications.

The working principle of the H821K5BYA is based on the amount of resistive material between two terminals, which consists mainly of carbon film. This type of resistor is called thick film to distinguish it from wirewound resistors. The resistive material is typically a ceramic substrate with a metal film layer on top. The combination of metal and ceramic substrate results in superior resistivity, high power rating, and a wide range of temperature coefficients.

The H821K5BYA is a through-hole resistor, which means that the leads of the resistor are inserted into the through-holes of the printed circuit boards (PCBs). The PCBs then conduct the electrical current through the resistor in order to achieve the desired resistance value and circuit connection.

The H821K5BYA is a dependable and cost-effective resistor for any low-frequency applications. Its versatility, reliability, and wide range of resistances make it a popular choice for manufacturers and engineers.
