Polarity of Resistor

Polarity of Resistor

Resistors have no polarity.

Therefore, when mounting resistors on a board, it does not matter in which direction they are mounted. There is no need to be aware of positive (+) and negative (-) as with electrolytic capacitors.

However, aligning the orientation of the resistors makes the color code easier to read.

For example, when the resistor is mounted upright, the color code should be read from top to bottom. When the resistor is mounted lying down, the color code should be read from left to right and from top to bottom.

It is easier to check the circuit if the resistors are oriented in the same way on the board.

Polarity of Network Resistor

Polarity of Network Resistor

We said that resistors have no polarity, but there is an exception.

Network resistors that have a common terminal at one end have an orientation.

When using the network resistor, reversing the orientation of the network resistor will result in different the resistance value.

For example, suppose there is a 6-pin group resistor with each resistance value of 100Ω.

If the resistor is mounted in the reverse orientation, the resistance value between pins 5 and 6 will be 200 Ω, while the value between pins 1-2 will be 100 Ω if the resistor is mounted in the normal orientation.
