You will find many suppliers of electronic components who will sell them in small quantities. Suppliers of new components, or in a few cases “new and some used” components, include Digi-Key (having blue LEDs, prices reasonable), Mouser Electronics (Fast service, $20 minimum, $5 charge under $20, export orders $100 minimum), Ocean State Electronics (good collection of RF parts, especially air variables and B&W coils), Radiokit (lots of components), Circuit Specialists Inc ( no minimum with check or money order, or else $15, good RF collection), Active Electronics (many stores across the US and Canada, $25 minimum), Maplin Electronics Ltd. (UK), Newark Electronics ($25 minimum, prices on the higher side but have a lot of things that are hard to find elsewhere), Arrow Electronics, Inc. (minimum $25, accepts personal order also), MCM Electronics (minimum $20, mostly VCR parts and lots of useful stuff difficult to find elsewhere), and Fordham Radio Supply (tools for technicians).
Other companies include Jameco (computer parts and electronic components), JDR Microdevices (now no minimum order), Johnson Shop Products (new and some used electronic components), DC Electronics (good collection of ICs and electronic components), International Components Corporation (capacitors, diodes, ICs, potentiometers, resistors, sockets; transistors), Kelvin Electronics (minimum $20, lots of electronic parts and tools), H & R Company (Herbach and Rademan) (minimum $25), John Birkitt (good stocks of new components and tools), N R Bardwell (cheap, good stocks of ICs), Surplus Electronics ( resistors, capacitors, and some semiconductors),
All Electronics Corp. (minimum $10, new and surplus electronics), Alltronics (surplus electronics, $12 minimum), American Science and Surplus (formerly JerryCo),
Hosfelt Electronics (surplus electronics), and Marlin P. Jones & Assoc.(surplus electronics).

You can also consult wholesale directories to find details about suppliers of electronic components, compare prices and features, and finally make your choice.
Electronic items are loved by all. However, do you know about the precautions that you need to take while using electronics? Well, not many do know a lot about the precautions that need to be taken. Electronic items can be delicate and it is necessary that the proper precautions are taken to protect the device.
Understanding the basics
Electronics and electrical equipments are a very important and inevitable part of day to day lives. However, one needs to know how to handle and use these electronic items as well.
Precautions while handling electronics
All the electrical appliances and electronics are semiconducting devices and have circuit designs. So it is very important to handle them properly so as to minimize damage and malfunction. Circuits can malfunction under different circumstances. One of the most common causes of damage to these electronics is the application of stress like variation is temperature, the rate of current flow and the voltage applied. These variables should always be kept within the limits which are permissible by the manufacturer.
Protection of the pins
Pins are those minute things that connect the semiconductor devices present in the electronic appliances to the power supply or the input and output sources. When the pins are connected to the high output sources, care should be taken to prevent shortening of the circuit. This could lead to damage of the appliance and may decrease the life of the appliance. Also, the unconnected pins should never be connected to currents of high impedance as it can also lead to damage of the electronic appliance.
Precautions while using electronics
Most electronic devices come with some instructions which should be kept in mind while using them. The manufacturers as well as users should keep these instructions in mind and take precautions. For instance, if you buy a hand held game console, the precautions state that you should not expose the device to water and should take regular breaks while playing.
Precautions while storing and transporting electronics
Storing the electronic devices properly is also very important. Since all semiconductor electronics are made up of very minute and delicate electronic circuits, they should be stored with proper care. They should be kept away from moisture, extreme changes in temperature and heat. To avoid damage during transportation, these electronics are stored in big aluminum containers with silicon coating to prevent damage during storage as well as transporting the electronics.
Also, one other important thing which should be kept in mind is that electronic items made up of plastic bodies are highly susceptible to fire. Also, in case of an emergency, one should always call in for help and be cautious not to go near the appliances. Electronic items should be properly charged as well, like in the case of computers and mobile phones. At the end of the day, you need to understand that electronic items and electronic devices should be kept and stored properly in order to use them for long.
Understanding the world of electronics
Statistically, the number of electronic goods sold has gone up phenomenally in the last few years. With the industrialization of the world, it is simple to assume that the sale of electronic goods and items will just double or even treble in the coming years. Given this fact, it is absolutely essential that people know how to handle the electronic goods, especially electronic gadgets that need to be handled with utmost care. Not knowing how to take proper care of your electronic gadget can be costly and can lead to health problems as well as damaging the electronic device itself.
