Through Hole Resistors are electrical components that are designed to provide a specific amount of resistance or to limit current flow in an electrical circuit. The H87K87BYA is a specialized type of through hole resistor that is designed to be used in commercial and industrial applications. This article will discuss the application field and working principle of the H87K87BYA.

The H87K87BYA is an inch-high, through hole resistor that is designed for use in PCBs. It is a non-ceramic, low-impedance resistor with low thermal resistance and high reliability. It is suitable for both analog and digital applications. The rated power dissipation of the H87K87BYA is three watts and it has a maximum operating temperature of 260 degrees Celsius.

This type of through hole resistor is typically used in power supplies, motor control, inverters, and other equipment where an efficient and reliable power resistor is needed. The H87K87BYA is also commonly used in high-powered amplifiers, high-voltage circuit boards, and switch mode power supplies.

The H87K87BYA has a tolerance of ±20%, meaning that the actual resistor value can be +/-20% of the specified value, depending on the type of resistor and the application. The H87K87BYA also has a low thermal drift, which means that its resistance remains relatively constant over a wide temperature range. This feature makes the H87K87BYA ideal for power supplies, inverters, and other applications where temperature stability is important.

The working principle of the H87K87BYA is based on Joule heating. When electrical current passes through the resistor, joules of heat are generated, which is why it is referred to as “Joule Heating”. Joule heating is an important factor to consider when selecting a through hole resistor. As the internal resistance of the resistor increases, joules of heat are generated and result in a higher operating temperature of the resistor.

The H87K87BYA has a high power dissipation rating, meaning it can dissipate up to three watts of heat without any problems. It also has a low thermal resistance, which allows for a more efficient heat dissipation. This makes the H87K87BYA an ideal choice for applications where heat dissipation is critical and must be controlled.

The H87K87BYA is a highly reliable and efficient through hole resistor that is suitable for a variety of applications. It is ideal for use in power supplies, motor control, inverters, and other equipment where an efficient and reliable power resistor is needed. It has a high power dissipation rating and low thermal resistance, which make it a great choice for applications where temperature stability and heat dissipation is important.
