Your calculator is not correct! Notice that the number of zeroes is equal to the color's number as per the previous table. The 6th band for a 6-band type resistor is the temperature coefficient. Enter the first five colors. Yellow, violet, gold, gold, yellow --> 4.7 ohms, 5% - this resistor is calculated with the 4-band rule (the yellow band is ignored). As shown above, a carbon-composition resistor can have 4 to 6 bands. This gives the two-digit value 47. The printed colors gives an accurate representation on the value of the resistor. A Voltage divider calculator calculates the voltage drops on each resistor load, when connected in series. yellow - violet - orange - red. Resistor Calculator is an App developed by CherryJourney to help the user find the value of a resistor. Two first bands (first band is the one nearest the end of the resistor) indicates the value, the third indicates the multiplier and the fourth indicates tolerance. how do calculate the value of a resistor using the colour band is it from left to right or right to left ? A 5 band resistor is more precise compared to a 4 band because of the inclusion of a third significant digit. This calculator has not this option. 3.) Resistor Series. Can you explain the problem in a different way? It is too difficult to find the exact value of resistors that you have calculated. An example calculating the range of a resistor value is: If the nominal value was 34 Ohm and the 4th band of the resistor was gold (5%) the value range would be nominal +/- 5% = 32.3 to 35.7. Standard-tolerance SMD resistors are marked with a simple 3-digit code. Don't have an AAC account? The resistor calculator tool calculates the color code for 3band, 4 band, 5 band, and 6 band resistors typically in the range of ohms, Kilo Ohms, and Mega Ohms. Therefore, when in doubt (and when it's possible) don't hesitate to use your trusted, old friend -- the multimeter -- to double-check the critical components. You don't have to enter the 4th band, as 20% resistors don't have a tolerance ring. Standard-tolerance SMD resistors are marked with a simple 3-digit code. Related Products: Kits and Tools January 2, 2013 by Donald Schelle, Field Applications Engineer, Texas Instruments Comments 12. But This is the minimum required resistor value to ensure that resistor will not overheat, so its recommended that to double the power rating of resistor that you have calculated, therefore, choose 0.047W x 2 = 0.094W = 94mW resistor for this circuit. For example, if you’re calculated value of resistor power rating is 0.789W = 789mW, then you would select 1W Resistor.

A resistor is a perhaps the most common building block used in circuits. Most chip resistors are marked with a 3-digit or 4-digit code -- the numerical equivalent of the familiar color codefor through-hole components. Sometimes we need a resistor value more precice than what is offered in the standard series. This calculator can determine the resistance of up to 10 resistors in parallel. The correct tolerance limits should be 199.8K - 200.2K. An example calculating the range of a resistor value is: If the nominal value was 345 Ohm and the 5th band of the resistor was gold (5%) the value range would be nominal +/- 5% = 327.75 to 362.25. Resistor Calculator is an App developed by CherryJourney to help the user find the value of a resistor. Carbon composition 1/8, 1/4, and 1/2 watt resistors all come in the same basic form factor and have either 4, 5, or 6 color bands. Therefore, select the next higher value of power rating. Enter the total voltage supply, Resistance of first load, second load and third load and click calculate. When resistors are produced in accordance to military specifications, they will often include a band that indicates reliability. Resistor Value. Funny, I never heard that mnemonic, but something similar which I won’t repeat. Hi Jason. Download 8.5 x 11 PDF. The number of bands is important because the decoding changes based upon the number of color bands.

The calculator above will display the value, the tolerance and performs a simple check to verify if the calculated resistance matches one of the EIA standard values. To calculate the minimum and maximum resistance values, we multiply the resistance value by the tolerance percentage to come up with the following values: Minimum = 750000 - (750000 x 5/100) = 750000 - 37500 = 712500 = 712.5kΩ Hover above the tolerance for min. Each color represents a number if it's located from the 1st to 2nd band for a 4-band type or 1st to 3rd band for a 5-band and 6-band type. In this software, you have 8 color codes for tolerance level, which include brown, red, green, blue, violet, silver, gold, and grey. Mnemonics were created to easily memorize the sequence of the colors. A single black band on a resistor is called a zero-ohm resistor. The electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, and others. Although the program was tested rigorously, it still may have a few bugs. SMD resistor code . Quantization errors in resistor values are inherent to Javascript.

This resistor value of R2, is calculated by the formula, R2= (VOUT * R1)/(VIN - VOUT) . has a value of 47 kΩ with tolerance +- 2%. Where, ‘a’ represents the 1 st significant digit, which is the first band color of resistor. Hold the resistor with the closely grouped bands to your left and read the resistor from the left to the right. It is used as a wire ( act as a jumper) to connect traces on a printed circuit board (PCB). Who’d make these days a ±0.05% tolerance resistor and mark it with color bands? and max. The first 3 or 4 bands give the basic value in ohms, of the resistor. Create one now. If you calculate a 200K resistor with a tolerance of 0.1%, the calculator will give a tolerance floor of 180K and a ceiling of 220K, which is correct for 10% tolerance, not 0.1%. Resistor Color Code Calculator Resistor Color Code Calculator. For more information about this can be found in the US military handbook MIL-HDBK-199. You will get the results of voltage drops in volts. Enter the total voltage supply, Resistance of first load, second load and third load and click calculate. In order to prevent metal and other particles from getting in the coating of high voltage resistors, the gold and silver bands are often replaced with a yellow and gray band. roper_ni. Voltage Drop Across a Resistor Calculator . Arduino or Raspberry Pi tinkerer? For this task, use the Resistor Value Calculator. Resistor Color Code Calculator decodes value and tolerance of 4 and 5 band resistors. Resistors can have 3, 4, 5 or 6 color bands printed on them.
