Hi boys and girls!
In RF electronics, not only capacitances and impedances can change with temperature, time etc, but also resistances. As a rule of thumb, engineers do not use carbon film resistors but rather metal film etc.
Now my problem is that i have a batch of smd resistors that i would like to test their reactance on.
How do one know if a smd resistor is carbon film or metal film? How can one test the reactance of the smd resistor in a reliable way?
Any help would be appriciated.
