Chassis Mount Resistors (CMRs) are resistors mounted to the chassis of electronic devices. The 850FR70E series of CMRs is specifically designed to provide reliable, high-performance operation for a wide range of applications. The 850FR70E is constructed from a combination of high-temperature resistant materials, and features a high thermal range along with superior vibration and mechanical shock resistance.

Application Field

The 850FR70E series of CMRs are designed for many different types of applications, including: Automotive electronics, Military electronics, Medical electronics, Aerospace electronics, Industrial electronics, and Telecommunications.

In automotive and military electronics, the 850FR70E series is well-suited to providing reliable and efficient power control in harsh environments. The series’ superior temperature range makes it a great choice for controlling both hot and cold temperatures. The high vibration and mechanical shock resistance of the 850FR70E make it a great choice for applications requiring that type of protection.

In medical electronics, the 850FR70E is an ideal choice, due to its low leakage current and high temperature range, making it suitable for any medical device operating in a wide range of temperatures and other conditions. In aerospace and industrial applications, the 850FR70E provides reliable, uniform resistance, making it ideal for systems that require precise and high-accuracy resistors.

Telecommunications is another area where the 850FR70E series is ideal. The series is designed to provide superior noise and surge protection, making it a great choice for protecting telecommunications equipment from interference and other external threats.

Working Principle

The 850FR70E series of Chassis Mount Resistors is based on a simple principle: that of resistive heating. This is the process of passing an electrical current through a resistor to heat it up, in order to reduce its resistance value. The 850FR70E’s heat output is very uniform and controlled, allowing for consistent and reliable performance in any application.

The 850FR70E is made up of two parts: a metal contact block and a metal resistor. The contact block features two or more contacts connected to a metal resistor, which is made up of multiple layers that resist heat in the form of resistive heating. The contact block passes an electrical current through the resistor layer, creating heat which is then transferred into the surrounding environment. This heat is then used to reduce the resistance value of the resistor layer. The 850FR70E is designed to be extremely durable and reliable, and can handle high temperatures without any issues, making it an ideal choice for many industrial and automotive applications.
