Chassis Mount Resistors

Chassis mount resistors are widely used in automotive, HVAC, and industrial control applications. These resistors are designed to mount onto metal panels or frames and are constructed of rugged materials to avoid corrosion or wear. They can be attached directly to the devices they protect and simplify the installation process.

EWT225JB2K00 Application Field and Working Principle

The EWT225JB2K00 chassis mount resistor is a 1206 (0603 metric) chip resistor with a ±2% tolerance. This resistor is ideal for applications such as DC motors, fan controls, controllers, voltage regulators and power supply circuits. Its maximum dissipation power is 2.5 watts and it operates at temperatures ranging from -55°C to 125°C.

The main principle of this resistor is to reduce current. By introducing resistance, the current passing through a circuit is decreased. This is achieved by letting electrical energy dissipate into the environment as heat. Since current is inversely proportional to resistance, a higher resistance will result in a lower current. This makes the EWT225JB2K00 perfect for applications where a lower current is desired.

The EWT225JB2K00 features excellent heat dissipation with its 1206 footprint having a 275 °C/W thermal resistance. Additionally, it has a ceramic body which is crack and corrosion resistant. Its low profile construction makes it easy to mount on a frame.

The EWT225JB2K00 is highly reliable due to its high stability rating of 0.05%. It is also RoHS compliant and does not contain any hazardous substances which ensures its environmental friendly design. It has a rated power of 2.5 watts.

The EWT225JB2K00 is a cost-effective and reliable solution for applications such as motor controllers, voltage regulators and power supplies. Its small size, high power dissipation capabilities, and high reliability make it ideal for industrial, automotive, and HVAC control applications.
