A chip resistor is compact, surface mounted electronic component that is designed to proffer resistance to electric current through it. The mini resistor is designed to have similar characteristics or form factor as other surface mount. It differs from classic axial lead resistors in physical terms only and it fulfills the same function as in case of electronic circuits. Chip resistors are available in different package formats and it comes with a wide range of features. There are a wide range of companies that offers SMD Resistors and capacitors. Further, these are offered according to the specification and requirements of the clients. The SMD resistor is widely used in electronic industries at cost effective prices. A chip resistor tends to be slightly larger than a pin-head. It encompasses of a lead that is designed on the either end and is specifically used for surface mounting. The printed circuit board construction method allows more room for complex circuitry but it also facilitates multi-layer PCB construction. In the conventional methods of PCB construction the component leads are inserted through the method of holes in the holes and then it soldered on the reverse side. The modern surface technology has undergone a sea change; these components are soldered directly on the conductive tracks as they are mounted. The axial lead resistors donâ€™t allow this kind of PCB construction and this has led to the emergence of the chip resistor. A chip resistor is constructed using the sputtering techniques where the vacuum deposition is applied on a resistive carbon composite, ceramic or a metallic material that is applied on an insulating backing. There is a certain kind of resistors that is encased in a protective coating. Moreover, the materials used to manufacture the resistor are in strict
adherence to the international standards. These kinds of resistors have minimal amount of chromium, cadmium and lead. There are two kinds of chip resistors- single resistor and chip resistor array. The single resistor is passive and has a set value component, while resistor array has several resistors in a package. These resistors have battery of terminal leads whereas the chip resistor arrays are in line with several kinds of pin that are representing a single pin for each resistor in the array. The chip resistors can be classified on basis of its usage. For instance, some of the resistors are perfect for power supply, automotive industry, medical industry and some for aerospace industry. Above all, they are equipped with latest features like heat sinks, fireproof shield and watercooling facility. Above all, there are innumerable companies that offer a wide range of SMD resistors, which in turn finds application in a variety of industries. These resistors have high speed switching power supplies and snubber circuit.
