These are being highly used since the introduction of surface mount technology. These can be termed as chip resistors, which means a resistive layer integrated on a ceramic chip.

These surface mount resistors are very small when compared to the normal resistors and hence occupy less space. They are effective and dissipate less heat. The invention of these resistors has changed the look of a PCB (Printed Circuit Board) and reduced its size greatly.

The advantages of surface mount resistors are −

• These are compact in size.
• These are very stable.
• They have good tolerance.
• They are effective in reducing heat dissipation.

The following figure shows the images of surface mount resistors.
