Through Hole Resistors, such as the H87K87BDA, are among the simplest electronics components. They are primarily used for short-term current and voltage regulation or as part of a voltage divider circuit. The resistors are formed from a material with a high electrical resistance – usually a ceramic, metal, or semiconductor substrate. The primary purpose of these resistors is to absorb and dissipate excess electrical energy, to protect other components from an overload, and as part of an electrical circuit to regulate the voltage and current levels.

The H87K87BDA is an axial “through-hole” resistor, meaning it has an axial lead that passes through a cylindrical sleeve of insulating material to connect it to its printed circuit board. It is composed of a wire housing with a ceramic insulator, typically at a temperature rating of 85°C (or 185°F). There are three resistance values available for this type of resistor – 1.2K, 4.7K and 10K ohms. The 1.2K resistor is a cool-running type, and it is well suited for applications where high temperatures are not desired.

The working principle of the H87K87BDA is quite simple. It consists of two parts, a heatsink and an electrical current regulator. The heatsink dissipates heat generated during the operation of the resistor, while the electrical current regulator dissipates excess electric current. This resistor works by taking the input voltage and converting it into equal but opposite voltages, known as the output voltage. The output voltage is then regulated by the electrical current regulator, which keeps the output voltage constant regardless of changes in the input voltage.

The H87K87BDA resistor can be used for a wide range of applications, including electronic test and measurement equipment, RFID, automotive, and medical equipment. It is also suitable for use in circuits that require low inductance and have moderate operating temperatures. It is easily installed in most printed circuit boards or components, and its axial lead design allows for quick and easy installation. The H87K87BDA is an economical and reliable component for short-term voltage and current regulation.
