What are the dimensions of surface mount resistors?
SMD resistor sizes. The shape and size of surface mount resistors are standardized, most manufacturers use the JEDEC standards. The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the width and height of the package.
What kind of voltage do I need for a 5 Ω resistor?
These are the typical voltages used by hobbyists for their projects. Just use the standard resistor values chart to find the nearest highest value available. Example 1: The blue LED has a typical forward voltage drop of 3.2 V, therefore a 5 Ω resistor is required when using a 3.3 V supply voltage.
What is the spacing on a four band resistor?
Which of these the color refers to is dependent on the position of the color band on the resistor. In a typical four-band resistor, there is a spacing between the third and the fourth band to indicate how the resistor should be read (from left to right, with the lone band after the spacing being the right-most band).
What are the specs for a resistor in a car?
Resistor Specifications: Resistors have two main parameters. The first is its resistance in ohms. The second is its power rating in watts. There are other specs such as maximum working voltage but its power rating and resistance value are the most important in car audio systems.
How big is a 1 / 4 watt resistor?
1/4 Watt Resistor – 2.5 x 6.5 x 28: It handles 27.77 mA when connected to 9 V source 1/2 Watt Resistor – 3.2 x 8.5 x 28: It handles 55.55 mA when connected to 9 V source 1 Watt Resistor – 5 x 11 x 28: It handles 111.11 mA when connected to 9 V source 2 Watt Resistor – 5.5 x 15 x 35: It handles 222.22 mA when connected to 9 V source

How big of a resistor should I use?
Typical sizes for small resistors are 1/8 Watt, 1/4 Watt, 1/2 Watt, 1 Watt, and so on. So in our case a 1/4 Watt (0.25) might be on the small size, but a 1/2 (0.5) Watt resistor should be fine. Using a larger Wattage resistor is almost always OK.
