H4249RBCA is a type of through hole resistor, often utilized in military and aviation applications, medical devices and more.In this article, we’ll explore the application fields and working principles of H4249RBCA, as well as the properties and features that make it unique within the world of through hole resistors and related applications.

Application field and working principle of H4249RBCA

H4249RBCA is a through hole resistor that is often used in military and aviation applications. It provides electrical and thermal stability in high voltage and high temperature environments, making it ideal for harsh environments where a high degree of resistance accuracy is required. Its application field includes A-E test, automotive, commercial, energy, instrumentation, and medical applications.H4249RBCA takes a basic resistor structure and modifies it with unique features to ensure maximum performance in any application. The resistor is composed of a conductor made of a ceramic body which is surrounded by a non-conductive medium such as an oxidation inhibitor or a dielectric. A thin strip of metal, usually made from aluminum which is surrounded by a ceramic sleeve, is then placed over the body. This strip acts as the resistance, and as current flows through the strip, it produces heat which is dissipated through the oxidation inhibitor or dielectric medium.The working principle of H4249RBCA is simple enough. When the power supply is turned on, electric current passes through the tiny strip of metal. As the current flows, the metal strip heats up, which produces resistance. As the strip of metal heats up, it dissipates the heat through the dielectric or oxidation inhibitor through which it is surrounded. This dissipates the heat from the resistor and prevents it from overheating, ensuring that it maintains its resistance.
