WebPassive trimming involves the adjustment of a single resistor to a required value, while active trimming alters the entire circuit output, traditionally voltage, switching threshold or frequency. Both can be used with all three lasers (IR, Green and UV). WebJul 31, 2024 · So you can “trim” the value of a resistor up connecting a second resistor in series: to trim up, choose an available resistor value below the target value, then add a (much smaller) series resistor to make up the difference." For the series case, the equivalent resistance of two resistors in series will be the sum of the two resistor values.
