K resistor

Enter the characters you see below Sorry, we just need to make sure you’re not a robot. Typically, they k resistor manufactured using thin-film technology. There are two basic configurations for chip resistors: single resistor and resistor chip array. Single chip resistors are standard, passive resistors with a single resistance value. How to Use the Resistor Color Code Calculator Are you having trouble reading resistor color codes?

If your answer is yes, then this tool is specifically designed for you! Our Resistor Color Code Calculator is a handy tool for reading carbon-composition resistors whether it’s a 4-band, 5-band or 6-band type. To use this tool, simply click on a particular color and number and watch how the actual bands on the resistor illustration change. The resistance value is displayed on the field below together with the tolerance and the temperature coefficient. Resistor Band Colors As shown above, a carbon-composition resistor can have 4 to 6 bands.

A 5-band resistor is more precise compared to a 4-band type because of the inclusion of a third significant digit. 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. Mnemonics were created to easily memorize the sequence of the colors. The most popular mnemonic is “Big Boys Race Our Young Girls But Violet Generally Wins” where the first letter of each word corresponds to the first letter of the color. If the color is found on the 3rd band for a 4-band type or the 4th band for a 5-band and 6-band type, then it’s a multiplier. 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.

This indicates how much the actual resistance value of the resistor changes when the temperature changes. Five band resistors with a fourth band of silver or gold form an exception, and are utilized on specific or older resistors. Deviating Colors 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. Single Black Band or Zero-Ohm Resistor A single black band on a resistor is called a zero-ohm resistor. This packaging allows the zero-ohm resistor to be placed on the circuit board using the same equipment typically used to place other resistors. Reliability Band When resistors are produced in accordance to military specifications, they will often include a band that indicates reliability. This band is specifically for failure rate percentage per 1000 hours of service. This band is almost never used in commercial electronics.

4M7 or 100R. Sometimes include an extra band to indicate reliability. So that each value is greater than its predecessor by a fixed multiplier or percentage, commercial production of thermistors did not begin until the 1930s. The resistance of NTC thermistors exhibit a strong negative temperature coefficient, making sourcing much easier and the cost of the components much less. There is often no need for them to be marked.

Four band resistors typically use this reliability band. For more information about this can be found in the US military handbook MIL-HDBK-199. I’ll never forget the basics of this. Some of the stuff, though, is esoteric as hell. Funny, I never heard that mnemonic, but something similar which I won’t repeat. I would like a version that I can have on my computer because I don’t always have a connection.
