Through Hole ResistorsA through-hole resistor is a type of resistor designed to be mounted to printed circuit boards (PCBs). Through-hole resistors are large cylindrical components that are soldered to the board, rather than being placed on the surface of the board via soldering or surface mount technology. Through-hole resistors are often used in industrial and military applications, where their solid construction and reliability make them ideal for harsh environments.The H812R1BCA is a through-hole resistor developed by Bourns. This resistor has a high power rating of 12W, a high voltage rating of 2500V, a wide tolerances value of ±2%, and a low temperature coefficient of -200ppm/°C. These features make it suitable for a range of applications, including high-voltage power supplies, motor controllers, and other industrial and military applications.The working principle of the H812R1BCA is simple. When an electrical current flows through the device, a certain amount of resistance is created which limits the amount of current that is allowed to pass. This prevents sensitive electronics from being damaged by over-loads and provides a way to control the amount of current in a circuit. The amount of resistance created by the H812R1BCA can be adjusted by choosing the appropriate size of the components, which allows for fine-tuning of the current levels in a circuit.The H812R1BCA is often used in automotive, telecommunications, and industrial applications. In automotive applications, the device is used to control the flow of current in several components, like starter motors, spark plugs, and lighting systems. In telecommunications applications, it is used to limit the amount of current that is allowed to pass through wires in order to avoid damaging sensitive equipment. In industrial applications, the device is used to precisely control current levels in robotic systems, motor controllers, and other components that require exact current control.The H812R1BCA can also be used for other applications, including household electronics. By limiting the amount of current that is allowed to pass through a device, it can protect other sensitive components, like printed circuit boards, from over-voltage or over-current conditions. The device can also provide protection against power surges and other electrical disturbances, ensuring that sensitive devices do not become damaged.The H812R1BCA is a reliable and cost-effective option for a range of applications. The resistor offers a wide range of adjustment, a high power rating, and reliable performance in the most demanding conditions. Its combination of features make it an ideal device for both industrial and commercial applications, and its robust construction ensures that it can withstand extreme conditions.
