The H815R4BCA through hole resistor is a key component in any electrical system design, providing control and stability in a range of applications. The H815R4BCA provides protection against overloads, excess voltages, and electromagnetic interference, and is used in commercial, industrial, and military applications.The H815R4BCA comprises a four-terminal metal oxide film resistor (MOF) that is sealed in a 1/4-inch colour-coded ceramic/plastic cap. It has a current capacity of 4A and a power rating of 25W when operated at a maximum temperature of 250°C. The resistor also features internal fusing, which provides additional protection against thermal runaway and electric overloads.The H815R4BCA is designed for use in harsh industrial and military environments, and is resistant to mechanical shock, vibration, and extreme temperatures. This feature makes the resistor an ideal choice for applications that require reliable performance under harsh conditions.The working principle of the H815R4BCA is based on the resistive film technology, which utilizes a metallic film of molybdenum-tungsten or nickel-chromium. The film is applied to a non-conductive substrate and then heated to form a metallic bridge between two electrodes. In this way, an electrical resistance is created and used to control the current flow.The resistance of the H815R4BCA can be adjusted by a variable voltage supply, enabling the user to control the power output. It can also be used in pulse transformer applications, which can be particularly useful in radio frequency transmission and reception.In addition, the H815R4BCA can be used in circuits that require shielding from external electromagnetic interference. The resistor provides a resistance to high frequencies that prevents the device from being affected by external radiation.The H815R4BCA is also widely used in the automotive and aerospace industries. Its ability to withstand extreme temperature ranges, vibration, and shock makes it well suited for use in tight spaces, such as engines, motors, and fuel cells.The H815R4BCA provides excellent protection against overloads, excess voltages, and EMI. Its reliable performance and wide range of applications make it a key component in all types of electronics systems.
