Isabellenhütte FMx Series

The new FMx resistor family from Isabellenhütte fills in the gab from 0.006Ω to 0.0015Ω.  This resistor series will be offered in chip sizes 1206, 1210 en 2512. the construction of this serie is well designed to create the best possible heat transfer without using big Cu-plates in the component, this make it possible to cool this compent via airflow or transfer it via Cu-plates in your PCB.

Application more and more require high power in a limited amount of space where hot spots are a no go. To measure the currents a low Ohmic resistor with a small possible footprint is a designers wish. A lot part are already available and the FMx is in test for many more please contact our specialist if you need a solution. Isabellenhütte can this serie an many more to fill in your application.
