A chassis mount resistor is a resistor that is mounted onto a surface. The chassis mount resistor usually consists of a ceramic core with wire-wound wound coils, encased in metal such as aluminum or stainless steel, and mounted on the surface using rivets or bolts. Chassis mount resistors are used in a wide variety of applications, including electrical circuits, radio frequency, lighting, and others. The F20J7K5E is one such chassis mount resistor, and is popular in many commercial, military and industrial applications.
F20J7K5E Application Field
The F20J7K5E is a popular chassis mount resistor used in many industrial applications. It is widely used for power supply circuits, as a low-power and high accuracy resistor, and has excellent heat dissipation characteristics. The F20J7K5E can also be used in radio frequency and lighting applications such as RF amplifiers, switch mode power supplies, radio receivers, LED drivers, loudspeaker amplifiers and pre-amps.
F20J7K5E Working Principle
The F20J7K5E is a wire wound resistor, and its working principle involves a wire coil wound around a ceramic core. The wire coil is typically made of copper wires, and the ceramic core is coated with a dielectric material to enhance insulation. When current flows through the F20J7K5E, it causes electrons to flow, creating a resistance. This resistance is proportional to the length of the wire, as well as the number of turns in the coil. The resistance can then be adjusted by varying the number of turns in the coil or the length of the wire.
The F20J7K5E is also designed for maximum heat dissipation, which helps protect it from overheating and other damage. It is usually mounted onto a chassis to increase its heat dissipation capability, and to prevent subjection to mechanical stress. Its size and shape can vary, but it usually has a 1/2” or 1” square form factor.
Conclusion
The F20J7K5E is a type of chassis mount resistor with excellent heat dissipation characteristics and is suitable for industrial applications. Its working principle involves a wire wound coil being wound around a ceramic core, and its resistance can be adjusted by varying the length of the wire or the number of turns in the coil. It is usually mounted onto a chassis to increase its heat dissipation capability and to prevent mechanical stress, and its size can vary.
