Again, we check the resistor color code chart for red, violet and yellow, and the first, second and third bands give the significant digits of 2,7 and 4 respectively. The fourth band is black, giving a multiplier value of 10 0. Hence, we will get a resistance value of 274 × 10 0 = 274Ω resistor conversions (see Resistor Conversion Chart). These charts will be a great study guide to help you master the resistor inside and out, backwards and forwards.

To use this tool, simply click on a particular color and number and watch how the actual bands on the resistor illustration change The 120 ohm resistor has a value ranging between 110 and 130 ohms. Following this logic, the preferred values for 10% tolerance resistors between 100 and 1,000 ohms would be 100, 120, 150, 180, 220, 270, 330 and so on (rounded appropriately); this is the E12 series shown in the table below
Note: The metal film resistors now widely used for axial resistors and the surface mount resistors are normally available in 1% and 2% tolerance ratings even when included in the E24, E12, E6 and E3 ranges. The E series values are split into two groups which have slightly different numbering, although they follow the same basic numerology: Up to E24: For this lower end of the E series used for.

Standard Resistor Tables (Based on EIA Preferred Values) Where electronics engineers discover the latest tools. Hardware design made eas 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. So in the example of 0603 Imperial code, this indicates a length of 0.060 and a width. The Resistor Color Code Calculator identifies the value and tolerance of a color coded resistor given its bands colors. Supports resistors with 3, 4, 5 and 6 bands These resistors have two bands for the resistance value, one multiplier and one tolerance band. In the example on the left these bands are green, blue, red and gold. By using the color code chart, one finds that green stands for 5 and blue for 6. The value is thus 56·100 =5600 Ω. The golden band means that the resistor has a tolerance of 5% Use the Resistor Color Code Chart (below) to understand how to use the color code system. When looking at the chart, note the illustration of three round resistors with numerous color code bands. The first resistor in the chart (with 4 bands) tells you the minimum information you can learn from a resistor. The next (a 5-band code) provides a.
We've created a simple chart to explain resistor color coding for you. Resistors are available in many different values, shapes, and physical sizes. Practically all leaded resistors with a power rating up to one watt have a pattern of colored bands that are used to indicate resistance value, tolerance, and sometimes even the temperature coefficient Resistor Colour Code Calculator. Farnell's resistor colour chart gives you band colours, resistance, and tolerance for various types of resistors to help you identify components in your electronics projects Resistor Color Code Calculator decodes value and tolerance of 4 and 5 band resistors. Resistor Color Code Calculator. Use this website to convert resistor color codes into resistor ohm value and tolerance. Color banded axial lead resistors with 4 or 5 bands are supported There are two main types of resistors: Standard resistors have four color bands. Three of the bands tell you the nominal value, which means the value the resistor was designed to have.The fourth band tells you the tolerance of the resistor, which indicates how far off the nominal value the actual resistance could be. (The manufacturing process isn't perfect, so most resistors are a little off.
Resistor Values are read starting from the line closest to the end of the resistor. They will either have 4 bands or 5 bands. If there are four bands then the first two are the value of the two most significant digits, the third is the multiplier, and the fourth is the precision Standard Resistor Values ( ±5%) 1.0 10 100 1.0K 10K 100K 1.0M 1.1 11 110 1.1K 11K 110K 1.1M 1.2 12 120 1.2K 12K 120K 1.2M 1.3 13 130 1.3K 13K 130K 1.3
Resistor tolerance is a measure of the resistors variation from the specified resistive value and is a consequence of the manufacturing process and is expressed as a percentage of its nominal or preferred value. Typical resistor tolerances for film resistors range from 1% to 10% while carbon resistors have tolerances up to 20% Standard Resistor Value Calculator: 1%, 5%, 10%. This calculator will select the closest standard resistor value, from 1% 5% or 10% standard EIA values, calculates the error, and prints out a table of the standard values for the given tolerance Notes: an SMD resistor with a marking of 0, 00, 000 or 0000 is a jumper (a zero-ohm link).; a chip resistor marked with the standard 3 digit code and a short bar below the marking denotes a precision (1% or less) resistor with a value taken from the E24 series (these values are usually reserved for 5% resistors) Parallel resistor values table. The table below gives values for resistors in parallel for a variety of values in the various tolerance, E-series categories. Column A gives the required resistor value, and column B gives the first choice combination for the parallel resistors. A second choice is shown in column C
