Chassis Mount ResistorsEVFL252EP4K7JE is a type of chassis mount resistor, used for controlling current, signal, and power in electrical circuits. It is an advanced resistor that is actively cooled and secured. This ensures that the resistor is able to handle high power loads without suffering from thermal overload.The EVFL252EP4K7JE consists of a base metal frame, which supports the conductor elements. The conductor elements are typically made of silver metal foil on a dielectric substrate. This combination gives the resistor excellent resistance and power properties. The conductor elements are also insulated with Kapton, a high strength polyimide film. This insulation prevents the elements from shorting out, and also helps to maintain good electrical performance over time.The EVFL252EP4K7JE has a rated power of 2W, and a resistance rating of 4.7k Ohm. It can operate from -55°C to +150°C, making it suitable for a wide range of applications. The resistor features low inductance, high current capability, and high frequency handling. It also has excellent thermal performance, as it is able to dissipate heat quickly and efficiently.The EVFL252EP4K7JE is typically used in power electronics, including motor control, power conversion, lighting, and automation. It is also used in radio, television, and satellite applications, as well as in military and aerospace applications. It is well suited for these applications due to its high power rating and excellent thermal management.The working principle of the EVFL252EP4K7JE is similar to most other resistors. It employs a J-FET (junction field-effect transistor) to control current. When a controlled current is applied to the J-FET, it creates a voltage drop across the resistor. This voltage drop is proportional to the resistance of the resistor. As the current increases, the resistance of the resistor also increases, creating a linear relationship between the current and the resistance.In addition, the EVFL252EP4K7JE features an active current limiting device. This device ensures that the maximum current that can flow through the resistor does not exceed the rated power. This helps to ensure that the resistor operates safely, even when loaded with high power.The EVFL252EP4K7JE is a reliable, highly efficient chassis mount resistor. Its excellent power rating, high resistance, and excellent thermal management capabilities make it ideal for a range of applications. Its active current limiting device helps to ensure safe operation in high power loads. As such, this resistor is an excellent choice for a variety of power electronics and military and aerospace applications.
