EWT25JB5K00

Chassis Mount Resistors

Chassis mount resistors are an important element of the electrical system of a device or machine. They are used to regulate the flow of electricity in circuits, ensuring that current levels are kept at a safe level. This can be especially important in circuits where high currents are present, as excessive levels of current can cause damage to components.

The EWT25JB5K00 is a particular type of chassis mount resistor which is designed for very high power applications. It is a surface-mount device, which means it is designed to be placed directly on the surface of the circuit board. The resistor consists of a flat film of ceramic material between two metal plates. The plates are connected to the metal housing of the device, and the ceramic film is used to ensure good heat transfer. This allows the resistor to dissipate heat efficiently, allowing it to handle high power loads with low risk of overheating.

The resistor’s working principle is relatively simple. When applied voltage is applied across the resistor, current is forced to flow through the ceramic film. As the current passes through the film, it meets resistance due to the ceramic material’s physical properties. This resistance subsequently results in the conversion of electrical power into heat energy, which is then dissipated by the surrounding metal housing.

The EWT25JB5K00 specific features a power rating of 25 watts and a resistance tolerance of 5K. This makes it suitable for applications which require a high level of current, such as car audio systems, lighting systems, and motor drives. It can also be used in high voltage applications such as medical devices and power supplies. In addition, it is UL certified for use in various US and Canadian applications.

In summary, the EWT25JB5K00 is a chassis mount resistor designed for high power applications. It is a surface mount device which uses ceramic material to resist current and dissipate heat energy. The resistor has a power rating of 25 watts and a resistance tolerance of 5K, making it suitable for many applications ranging from car audio systems to medical devices. As a UL certified device, it is suitable for use in various US and Canadian applications.
