PCB Resistor

The resistor is one of the basic electronic components for printed circuit boards. It can be broken down into the actual material they are made from, which has a huge effect on how they resist an electric current. These materials include: carbon composition, carbon film, metal film, thick and thin film, foil, wire wound.

Carbon composition is an older technique that has been around for a while and produces a resistor with a low degree of precision. You still can find these for use in applications where high energy pulses occur.

The older carbon film resistor, still in use when precision is not a concern.

Of all the resistor material types, wire wounds are the oldest of them all, and you’ll still find these in use when you need precise resistance for high power applications. These ancient resistors are widely known for being reliable even at low resistance values.

The wire wound resistor, the oldest and most precise resistor available.

Today, metal and metal oxide resistors are the most widely used, and are better for providing a stable tolerance and resistance, while also being less influenced by changes in temperature. 

The most widely used metal oxide resistor provides a stable tolerance and resistance, so you can easily find them in printed circuit boards.
