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 [...]

Book for electronics beginners

If you are new to electronics and want a good book to learn about circuits and electronic components, then I recommend that you check out this book: Getting Started in Electronics by Forrest M Mims III I've had my copy so long that it is almost time to replace it but even though it is an old, worn out copy, the information is still as good today as it was 15 years ago when I got my book. Of course, there are some things that won't be found in here, but for the beginner, you can't go wrong with Read more [...]

Android smartphone sales up a whopping 886%

Research firm, Canalys, reports that Android platform smartphone sales increased an amazing 886% in the 2nd quarter. An even bigger accomplishment is the fact that Android based phones now account for 34% of the market - topping all other platforms including Apple's popular iPhone platform. The press release from Canalys also reports that Android devices combined reached almost 475,000 units in Q2 2010 from no presence in the country a year ago. The Google-backed Android is available in phones Read more [...]

HTC Incredible’s real price tag: $163.35

iSuppli's Teardown Analysis Service conducted a study of the cost of materials for the HTC Incredible. The total was $163.35 for the parts and electronic components used to build the smartphone. Nearly 20% of the cost of the handset is from the processor which cost $31.40. Right behind the processor was the display and touch screen which is manufactured by Samsung. The display, which is an advanced Active Matrix Organic Light Emitting Diode (AMOLED), cost $31.20. In third place was the memory 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 [...]

Turn your old PC fans into mini wind generators

Here's a great project that you can do either to experiment with wind turbines or to generate some energy! While the amount of energy produced is not overwhelming, this project can sure get your brain moving in the right direction. The best thing about this project is that you probably already have everything you need lying around: Thick plastic bottle Old PC fan, bigger the better! A few feet of small wire A piece of wood about 1.5" square and around 20cm long Two lengths of steel 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 [...]

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 [...]
