Chassis mount resistors provide passive components for electrical systems, and are particularly useful for radio frequency (RF) applications. The RER75FR499MC02 is a type of chassis mount resistor which is designed for a range of applications that require high power handling, which generally require a high thermal capacity and a sturdy construction. The RER75FR499MC02 is a 500 watt rated, linear power resistor with a single-sided, flat-bottom construction.
The RER75FR499MC02 is designed to be used for a wide range of applications, ranging from as an RF load resistor to a heat dissipation device in audio/video applications, medical equipment, and power supplies. It is also used in high power switching applications, as well as in automotive applications.
The power handling of the RER75FR499MC02 chassis mount resistor is accomplished by using a ceramic substrate coated with an aluminum oxide insulation material which helps to reduce heat generated during operation. The device also features a large area, which reduces the risk of it becoming damaged by overheating. This large area also helps to reduce thermal resistance and allows for the device to dissipate large amounts of heat. The device is also constructed with two separate heat dissipation ports, which help to dissipate heat away from the device and its surrounding components.
The RER75FR499MC02 is also designed to have a good thermal shock capabilities and a wide temperature range. This is beneficial in applications where the temperatures may vary significantly. This device also offers a high voltage rating of 1500V, which helps to make it suitable for a range of high power applications.
The working principle of the RER75FR499MC02 involves the conversion of electrical energy to heat. This is accomplished through a combination of conduction and convection. The conduction of energy is achieved when an electrical current is passed through the resistor, and the convection of heat is generated from the thermal conductivity of the ceramic substrate. The large area of the device also helps to minimize the thermal resistance, allowing the resistor to dissipate more heat.
In summary, the RER75FR499MC02 is a highly efficient, high power handling, single-sided, flat-bottom chassis mount resistor. This device is designed to be used in a range of applications ranging from RF loads to heat dissipation in automotive and medical devices. It is capable of providing a good thermal shock capability and a wide temperature range, which is beneficial for applications which may require high temperatures. This device also offers a high voltage rating of 1500V, making it suitable for high power applications.
