## What is the value of SMD resistor?

The value of SMD resistor code 100 is 10 Ohms. Check why?

### What is a SMD resistor?

A surface mount resistor is a tiny rectangular ceramic body with silver conductive edges on either end. Also referred to as surface mount technology, an SMD resistor offers advantages in saving space on printed circuit boards (PCBs). It features the resistance value code printed onto it, where there is space.

How do I know what wattage resistor I need?

It’s calculated by multiplying the voltage difference across two points by the current running between them, and is measured in units of a watt (W). Light bulbs, for example, power electricity into light. But a resistor can only turn electrical energy running through it into heat.

How do you read the value of a SMD resistor?

For a three-digit SMD Resistor Code,

1. the first two numbers indicates the significant digits for the resistance, e.g. “22” indicates 22 ohms.
2. the third number will be a multiplier that must be multiplier by the first two numbers, or will indicate how many zeros should be added to the first two numbers.

## What is the tolerance level of SMD resistors?

Tolerance: In view of the fact that SMD resistors are manufactured using metal oxide film they available in relative close tolerance values. Normally 5%, 2%, and 1% are widely available. For specialist applications 0.5% and 0.1% values may be obtained.

### What does a resistor color code mean?

The resistor color code indicates the electronic value of a resistor. Manufacturers devised the universal electronic color code rating system in the early part of the twentieth century because the bands of color were much easier to read on a small resistor than tiny print, and were also cheaper to produce.

What is the color code for resistor?

Resistor color code Practically all leaded axial resistors up to one watt are marked with the electronic color code (international standard IEC 60062). The resistor color code is a marking system with colored bands that are painted on the resistor body. Together they indicate the resistor value and tolerance.

How do identify resistor values?

First Step. The Red band of the resistance value is 2 and the brown band of the resistance value is 1 from the table. Second Step. From the table, the third orange band has value 1000. Multiply this value to 21 i.e. Third Step. Last is the Gold band having tolerance value in 5% (0.05) from the table.
