Chassis mount resistors are an important part of most electronics systems. They provide passive electrical resistance for a variety of uses, including readout in the form of voltage, current, and power. They are also known as fixed value resistors, as they provide a fixed, predetermined resistance regardless of the power supply, or load, that is applied to them. EWT100JB250R is an example of a chassis mount resistor.
Application Fields of EWT100JB250R
EWT100JB250R is a part of the EWT product line, which stands for “Extended Wear Technology”. The intention of this technology is to increase the life and temperature range of the resistors, making them suitable for a variety of applications. Due to their high reliability, EWT100JB250R can be used in applications which have limited space and require extended life expectancies. Due to their compact design, they are particularly well suited for use in the automotive industry.
It is also often used in a wide variety of general-purpose electronic applications, ranging from power supply regulators, active and passive filters, Isolation amplifiers, and remote control systems, among others.
Working Principle of EWT100JB250R
EWT100JB250R is a two-part design, with an insulating case and an electrical conductor. The electrical conductor is typically made of a highly conductive material such as gold, platinum, or copper. When a current is applied to the resistor, the electrical conductor is heated to produce a resistance between it and the electrical conductor, creating a resistance. This resistance depends on the type of conductor and its size. In EWT100JB250R, the resistance is usually adjustable using a screwdriver, allowing users to adjust the resistance to match the desired output.
One of the main advantages of this design is that it is relatively unaffected by temperature and humidity, meaning the resistor can be used over a wide temperature and humidity range. The EWT100JB250R also has a low power dissipation, which makes it particularly suited to applications which require low power draws, such as automotive electronics.
Conclusion
EWT100JB250R is an example of a chassis mount resistor which is suitable for a wide range of uses and applications. Its compact design and adjustable resistance make it a popular choice for automotive and general-purpose electronic applications, and its high reliability ensures that it can be used in applications which require extended life expectancies. The resistor’s low power draw and temperature and humidity resistance also make it particularly well suited for specific applications.
