Thick film technology pdf

The component is cut from the tape during assembly and the part is inserted thick film technology pdf the board. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Practical resistors as discrete components can be composed of various compounds and forms. The notation to state a resistor’s value in a circuit diagram varies.

SI prefixes corresponding with the part’s resistance. R” is used instead of the decimal separator. The total resistance of resistors connected in series is the sum of their individual resistance values. The total resistance of resistors connected in parallel is the reciprocal of the sum of the reciprocals of the individual resistors.

A resistor network that is a combination of parallel and series connections can be broken up into smaller parts that are either one or the other. Some complex networks of resistors cannot be resolved in this manner, requiring more sophisticated circuit analysis. This power is converted into heat which must be dissipated by the resistor’s package before its temperature rises excessively. Resistors are rated according to their maximum power dissipation. They usually absorb much less than a watt of electrical power and require little attention to their power rating.
