About This Product
The box holds 12 resistors on a printed circuit, and the rotary switch selects which one is connected to the two 4mm terminals. The terminals are yellow to show that the connections are non-polar. Resistance values have a 5% tolerance, although actual values are often closer to nominal.
Frequently Asked Questions
What is the tolerance of the resistors?
The resistance values have a tolerance of 5%, though in practice they are often closer to their nominal values.
What power can the resistors handle?
All the resistors have a maximum power rating of 1W.
