Chassis Mount Resistors

Chassis mount resistors are electrical components designed for use within electronic circuits. They come in a variety of sizes and types and typically consist of a metal housing, a ceramic core, and a conductor that is wrapped around the core. These components are used to reduce current or voltage levels, act as voltage or current dividers, provide a known load, or to protect sensitive components. Specifically, the RER70F2490MC02 Chassis Mount Resistor is widely used in many industries such as automotive, HVAC, industrial, medical, and telecommunication.The RER70F2490MC02 Chassis Mount resistor is designed with a wide range of power ratings, high thermal conductivity, and excellent resistance stability and corrosion resistance. This component features a 0.157 x 0.0787 inch (4.00 x 2.00 mm) metal housing and a 0.984 x 0.243 inch (25.00 x 6.20 mm) ceramic core. It also features a further power rating of 0.5 W, operating temperature range of -55°C to +125°C (-67°F to +257°F), and resistance value range of 0.06 Ω - 22 MΩ. It also covers a wide range of voltage and current limits including 5V-4A, 10V-2A, 250V-400mA, 500V-200mA, 1000V-100mA, and 15V-4A. The working principle behind the RER70F2490MC02 Chassis Mount Resistor is based on the concept of electrical resistance. Basically, when a current passes through a conductor, it experiences a certain electrical resistance, which is proportional to the material used and the size of its diameter. The resistance of a conductor decreases as its diameter increases while its material affects the rate of current flow. The resistance value of the RER70F2490MC02 Chassis Mount Resistor is determined by the number and type of materials used and the overall size of the resistor.The RER70F2490MC02 Chassis Mount Resistor is commonly used in automotive, industrial, medical, and telecommunication applications. It is used in automotive applications to act as a voltage divider to reduce the current or voltage levels in order to protect sensitive components. It is also used in industrial applications to resist EMI and RFI interference, as well as in medical applications to regulate electrical signals. Additionally, it is used in telecommunications systems to supply a known load or to regulate current and voltage levels. In summary, the RER70F2490MC02 Chassis Mount Resistor is a wide-ranging component designed for various applications. It features a metal housing, ceramic core, and conductor that is wrapped around the core. The component works according to the concept of electrical resistance and is used to reduce current or voltage levels, act as voltage or current dividers, provide a known load, or protect sensitive components, depending on the type of application.
