Chassis Mount Resistors

Chassis mount resistors are a type of electronic component specifically designed to be mounted and used inside the metal chassis frame of an electronic device. They serve to reduce or limit electrical current or voltage in a circuit, and are used to provide precise, reliable, locations for components such as transistors, capacitors, and other soldered assemblies. The term "chassis mount resistor" generally refers to a coated metal element that is designed to embrace the chassis frame itself, or an internal component connector.The RER75F1211RC02 is a typical example of a chassis mount resistor. Featuring a durable machined aluminum case, and a single-turn trimming element, the RER75F1211RC02 has a 12 K ohm resistance, and is rated at a maximum power handling capability of eleven watts. The case size is 75 x 12 mm, with a maximum operating temperature of +150 °C.The RER75F1211RC02 is designed primarily for use in automotive, industrial and commercial apps. Capable of handling high currents in a small, reliable package, the RER75F1211RC02 can be used for a variety of applications, such as temperature sensing, current limiting, and voltage regulation. In addition, the RER75F1211RC02 is compatible with robot systems, and is designed to fit in thin-slab chassis applications as required.The working principle of the RER75F1211RC02 is fairly simple. When the power is applied, the resistor creates a low-impedance barrier which limits the amount of current that can flow through it. This prevents overloading or damage to sensitive components such as transistors and capacitors. In some cases, a series-based trimming element can be used to adjust the resistance value to match the exact needs of the application.In addition to its power handling and temperature control capabilities, the RER75F1211RC02 offers excellent electrical characteristics. It features a lower thermal coefficient, making it well-suited for applications that require long-term reliability and precise temperature control. In addition, it has an excellent pulse power energy dissipation rating, making it a great choice for applications where precision and efficiency are key.Overall, the RER75F1211RC02 is a versatile and reliable chassis mount resistor that is well-suited to a wide range of automotive, industrial, and commercial applications. It offers superior electrical characteristics, temperature control, and durability, making it ideal for those looking for a reliable solution for their system.
