How do you determine the size of a resistor?

Read the 3 or 4 numbers on the resistor. The first 2 or 3 represent the significant digits and the last indicates the number of 0s that should follow. For example, a resistor reading 1252 indicates a rating of 12,500 ohms or 1.25 kilo-ohms.

What is the size of resistor?

The size of an axial resistor is relative to its power rating. A common ½W resistor measures about 9.2mm across, while a smaller ¼W resistor is about 6.3mm long.

How big is a 0805 resistor?

0.08 inches
SMD Resistors For example, an imperial 0805 resistor case will have a length of 0.08 inches and a width of 0.05 inches, while an imperial 0603 resistor package will have a length of 0.06 inches and a width of 0.03 inches. The imperial code is more commonly used in the PCBA industry.

What is a 1 4W resistor?

1/4W means – The maximum power dissapation should not exceed 250mW. 1/2W means- The maximum power dissapation should not exceed 500mW. U have to calculate the current through the resistor according to ur resistor value and find the power dissipation. P = I * I * R. If ur P is < 250mW then use 1/4W and vice vera.

How long is a 1/4 watt resistor?

6 to 7mm
Now there is certainly a common size for many resistors. Take for example 1/4 watt resistors. Of the 51,000 1/4 watt through hole resistors currently in our system you will find that 32,000+ of the options fall between a diameter of 2.29 and 2.5mm and a length of 6 to 7mm.

What is resistor wattage?

The Resistor Power Rating is sometimes called the Resistors Wattage Rating and is defined as the amount of heat that a resistive element can dissipate for an indefinite period of time without degrading its performance.

What is Watt in resistor?

The power rating of a resistor is measured in watts, and it’s usually somewhere between ⅛W (0.125W) and 1W. Resistors with power ratings of more than 1W are usually referred to as power resistors, and are used specifically for their power dissipating abilities.

How big is an 0201 resistor?

Surface Mount Resistors Size Chart

Size	Length (mm)	Height (mm)
0201	0.60	0.25
0402	1.00	0.35
0603	1.60	0.50
0805	2.00	0.50

What is 1W resistor?

What is a 1 2W resistor?

1/2W means- The maximum power dissapation should not exceed 500mW. U have to calculate the current through the resistor according to ur resistor value and find the power dissipation. P = I * I * R.

What is the dimension of voltage?

Voltage = Work / Charge (W/Q) Dimension of work = ML2T. Dimension of charge = IT (Current = charge / time). Which implies, the dimensional formula of voltage = ML2T-3I-1.

How big is a 5 watt resistor?

Resistors – 5 Watt, Wirewound, Power, 5% tolerance

Body Length	23.0 mm
Item Width	9.0 mm
Lead Diameter	0.8 mm
Lead Length	32 mm
Operating Temperature (TJ)	-55°C to 155°C

What does it mean when a resistor has a 1 watt rating?

The power rating of a resistor is the specification given with a resistor that serves to tell the maximum amount of power that the resistor can withstand. Thus, if a resistor has a power rating of 1/4 watts, 1/4 watts is the maximum amount of power that should be fed into the resistor.

What size are SMD resistors?

SMD resistors come in standardized sizes; usually either 0805 (0.08″ long by 0.05″ wide), 0603, or 0402. They’re great for mass circuit-board-production, or in designs where space is a precious commodity.

What is the size of a 1/2 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.

What is the size of a 3W resistor?

3 Watt Resistor – 6 x 17 x 35: It handles 0.4 A when connected to 9 V source 5 Watt Resistor – 7.5 x 24 x 38: It handles 0.8 A when connected to 9 V source Resistors above 5 watts are termed as power resistors and are usually available in different construction.

How much power can a 5 watt resistor handle?

5 Watt Resistor – 7.5 x 24 x 38: It handles 0.8 A when connected to 9 V source Resistors above 5 watts are termed as power resistors and are usually available in different construction.

What is the standard size of a surface mount resistor?

The shape and size of surface mount resistors are standardized, with most manufacturers using 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. So, the imperial code 0603 indicates a length of 0.060″ and a width of 0.030″.
