RSA-20-50 Datasheet/PDFChassis Mount Resistors
The RSA-20-50 type of chassis mount resistors are widely used in the industry for various applications. These resistors have a wide range of benefits over other types of resistors, such as providing a high level of accuracy, durability, and reliability. They are also relatively easy to mount and maintain.
RSA-20-50s are ideal for applications that require reliable operation in extreme temperatures, such as those found in automotive, medical, aerospace, and military applications. In addition, they have been used in industrial plant control systems, railways, communications equipment, and power supplies. These resistors are also capable of handling voltage ratings up to 50 volts.
Design
RSA-20-50s are designed with flange mounting and features a snap-in chassis mounting with a base for up to 50V. A marked power rating of 1W is possible using an epoxy coating that prevents any mechanical damages to the resistor. The common mount points of an RSA-20-50 are a 1/4 inch width in the center, and a hole that supports a #2 sheet metal screw located at each end. This allows for a flexible mounting.
Working Principle
RSA-20-50 resistors work by limiting the current flow in a given circuit. When being used in a circuit, these resistors will restrict the current flow in the circuit, allowing the electrical components and the rest of the circuit to work properly. This restriction helps to balance the current load of the entire circuit and prevents any overloading or electrical failures.
RSA-20-50s are a type of fixed-value resistor, which means that they have a pre-determined resistance value. This value is calibrated onto the resistor with a colored banding system which indicates the value of the resistor. This allows for a consistent resistance value to be achieved, making these types of resistors reliable and accurate.
The resistance value of an RSA-20-50 can be adjusted slightly by using special resistive elements called ferrites. These ferrites are used to increase or decrease the resistance value without changing the physical structure of the resistor. This method is commonly used for calibration and testing purposes.
Applications
RSA-20-50s have various uses in industry, such as in automotive, medical, aerospace, and military applications. They can also be found in industrial plant control systems, railways, communications equipment, and power supplies. These resistors are also used for calibration and testing purposes, and in safety equipment as well.
Besides the typical applications above, RSA-20-50s have been used in the entertainment industry, for example in stage lighting and audio equipment. The benefit of using RSA-20-50s in this type of equipment is that they are very reliable and accurate, which makes them ideal for this type of application.
RSA-20-50s are also used in consumer electronics, such as computers and cell phones. These types of resistors can help to improve the performance and reliability of these devices, and can also increase the energy efficiency.
Conclusion
RSA-20-50 type of chassis mount resistors are ideal for applications that require reliable operation in extreme temperatures. They are designed with flange mounting and a snap-in chassis mounting with a base for up to 50V. The resistance value of an RSA-20-50 can be adjusted slightly by using special resistive elements called ferrites. And this type of resistor can be used for automotive, medical, aerospace, military, industrial, entertainment, and consumer electronic applications.
