They may also have the manufacturers logo on them. There are many different types of diodes the most common are: Zener Diode: The Zener Diode allows current in reverse direction when the applied voltage reaches the breakdown voltage. good job for beginners like me. Doesn't a capacitor store a charge in the form of static electricity ? Now there are many different kinds of batteries such as lead acid or AGM batteries but i wont get into it to much as it doesn't really change the concept of the battery.

Just be careful not to jerk on the part or bump the board around and sent the molten solder flying everywhere! A few of them can be found at http://www.electronics2000.co.uk/ in the Calculators section. Fuses can be easy to identify, and typically have their voltage and amperage rating marked on them. 1 Diodes And now for a little test See how many components you can identify on the following board. thanks, I have retired from govt. Thanks for the information, I never thought of using the components before, untill I heard about your website by someone from instructables. The focus will be on common reusable through-hole components hobbyists will be most likely to scrounge and re-use. You can program them to do whatever you want. The characteristics of a diode closely match to that of a switch. hey nice info for a beginner like me,but it wud b advisable to add info about testing them in this or other articles…. on Introduction, Reply Thanks for taking the time to do this. The only reasonable way I can tell is take a soldering Iron and reheat the soder on the back of the board and pull the components off. 5 years ago, Hey this will help with some electrical designing I am doing, Reply Most are color coded, but some have their value in Ohms and their tolerance printed on them. 520M just went pop. it is quite beneficial and educative, THANKS THANKS THANKS YOU DONE A GREATE JOB. They are typically marked with an “VR” on a circuit board. This has been in my mind for a while maybe you can help me understand:Resistors, how do they limit I & V ?

Stepper Motors: The main difference between them and all the other motors, is the way they revolve. Thank you for any information. They are typically marked with an “X” or a “Y” on a circuit board.

There is also a chance of finding no information on a particular part. excellent… now i can start disecting all my electronics before i through them away. It is a vibrating device and that little round thing: G1. Retro Analog Audio VU Meter From Scratch! Something essential for hobbyists or new comers in electronics.

They may not be marked, but you can find some good general information on the web to help you out. http://www.classiccmp.org/rtellason/logos/semiconductorlogos.html, http://www.dialelec.com/semiconductorlogos.html, http://freespace.virgin.net/matt.waite/resource/logos/index.htm, http://hallaweb.jlab.org/tech/jackjack/public_html/manuals/chip_specs/Manufacturers%20of%20ICs%20and%20their%20logos%20-%202.htm, http://www.chipdocs.com/logos/logotypes.html?ReR=GG&ReR=GG. Any help? http://www.adobe.com/products/acrobat/readstep2.html, http://www.foxitsoftware.com/pdf/rd_intro.php, https://www.uchobby.com/index.php/2006/11/12/current-limited-pc-power/, https://www.uchobby.com/index.php/scrounging/how-to-heat-gun/.

on Introduction, This is great! (chip type) component foto for identify. thanks. This website will help you find the latest datasheet fast.

NOTE: I’ve written an updated guide to the basic electronic components. (if such an article exists,do let me know about it..) Answers can be found by scrolling below the board – No cheating! These are especially handy when it comes to designing portable devices. In your fridge, in your camera or in your phone. Search it and you will see the links for a datasheet usually go directly to the manufacturer. Heating the solder while pulling the components is tricky. The terminal marked positive is at a higher electrical potential energy than is the terminal marked negative. It functions as a two terminal current limiter. Motors is a device that converts direct current into mechanical power. 6 Inductors The latter being a very basic run down with lots of links to existing sites with detailed information. In this JFET acts as current limiter to achieve high output impedance. 2 Piezo Buzzer But how do you identify all those parts? The transistor acts either like an amplifier (Taking a small electric current at an input current and then produces a much bigger output current, you can see this at work in hearing aids or microphones) or like a Switch (taking a small current flowing through one part of a transistor can make a much bigger current flow through another part of it. Finding the manufacturer can be extremely useful as the most up-to-date information is usually available on their website. This article will give you some ideas on where to start. If they are color coded, the resources listed for resistors can help, otherwise a good meter that can measure inductance will be needed. Please try out the service and provide your feedback to support -at- datasheetpro [dot] com.”, “DSP Innovations has recently launched a FREE data sheet search site. different resistors can resist more than others the way you work out a resistors resistance is by looking at the 4 stripes on the main body of the resistor the different colors show the resistance, to work out the color code you can use a resistor calculator like this one: http://www.dannyg.com/examples/res2/resistor.htm.
