How Do You Read Resistor Values?

Resistors range from huge multi-watt giants to sub-miniature surface mount devices (SMDs) and parts with different types of leads in between. The larger varieties do not pose much of a problem as they usually have a big-enough surface for printing the value of the resistance, its tolerance, and other necessary specifications. For smaller sizes, codes are generally used for letting the user know the details of the resistor. Two common methods are under use for identifying resistors – color coding Read more [...]

Do wirewound resistors suppress noise?

Specially designed wirewound resistors are used as noise suppressors in automotive ignition systems for reducing RFI or Radio Frequency Interference caused by electrical discharges. These resistors are usually placed in the leads and or caps of spark plugs and in the rotor of the distributor. A gasoline engine generates high frequency electromagnetic Interference or EMI. This is commonly referred to as RFI or Radio Frequency Interference that comes primarily from the high-voltage side of the automotive Read more [...]

Learn about metal film resistors

Resistors are a common passive item in any electronic assembly. They are used for restricting the amount of current flowing in a circuit; acting much as a valve does in a water pipeline. The most commonly in use are carbon, thick metal and thin metal film resistors. The film forms the resistive material of the resistor. The axial resistor is usually a cylindrical conductive film on a non-conductive ceramic carrier. Two leads projecting from both ends of the resistance help in connecting the item Read more [...]

More Allen Bradley carbon comp resistors now available!

We've updated our resistor inventory and added many more NOS Allen Bradley carbon comp resistors. Between the 1W values and 2W values, we now have over 150 different 1W and 2W carbon comp resistors on hand! Included in the selection are many Military (MIL-SPEC) Allen Bradley carbon comp resistors. The military resistors typically have a tighter tolerance than the standard resistors. Allen Bradley carbon comp resistors are valued for their consistency and uniformity. The Allen Bradley corporation Read more [...]

Application information for Allen Bradley resistors

Allen Bradley resistors are one of the best sellers on the West Florida Components web site with good reason. The following information has been compiled to aid in the everyday selection and application of Allen-Bradley hot molded resistors. The statements should be helpful in evaluating the use of all types of AB hot molded resistors in broad general terms, and are not to be interpreted to be precise or exact. A comprehensive list is made of the standard normal resistance values in their Read more [...]

Opening Up and Tearing Down an IPOD Shuffle

Opening up and tearing down an IPOD Shuffle to see what's inside... The 3rd Generation of the IPOD Shuffle is a wonder of technology....1000 songs stored in an aluminum case smaller than a disposable lighter. Did you ever wonder what electronic components make up the guts of an IPOD Shuffle? You might be surprised at what goes into the circuitry of the IPOD Shuffle. In descending order by percentage of cost, the main components are: logic, memory, metals, rechargeable materials, connectors, Read more [...]

Resistors In Series

Electronic components used in electronic circuits to regulate and limit the flow of electric current in the circuit are known as Resistors. Resistors can be connected in two basic configurations – in series and in parallel. When connected in a series connection, the resistors are connected in a line. The current flows through the resistors one after the other. When the resistors are connected in such a configuration, they exhibit the following properties: The current flowing through Read more [...]

Understanding Resistor Values

Resistors are available in a wide range of values, but if you observe carefully you will realize that certain values of these electronic components like 15k ohm and 33k ohm are easily available where as some values like 20k ohm and 40k ohm are hard to find. Let’s try and understand the logical reason behind this. Take a hypothetical situation, where you make resistors every 10 ohm, thus giving you 10 ohm, 20 ohm, 30 ohm, etc. But once you reach the value of 1000 ohm, a difference of 10 Read more [...]
