What is a chip resistor?
The chip resistor is a very compact, surface -mounted electronic component designed to offer known resistance to any electric current flowing through it. The mini resistor of this kind is designed to have the same physical properties or shape factor as other surface mounting devices (SMD) to match the geometry of the SMD circuit plate. It differs from conventional axial lead resistors only in physical form and fulfills the same functions in electronic circuits. The trade unions of the chip are available in several AS packages with a number of specialized features. It has a line at both ends designed specifically for surface mounting. This method of printed board (PCB) (PCB) allows not only more complex circuits in any given area, but also facilitates the multilayer PCB design. Older PCB design methods demanded that the components were inserted into the openings of the in board and soldered to the location on the back. In modern surface assembly technology, these compones areNTY soldered directly to conductive tracks on the same side as mounted.
Larger, cylindrical axial lead resistors would not allow this type of PCB construction, which led to the development of chip resistor. The chip resistors are designed using thin film or spray techniques, where the vacuum deposition is used to apply a resistance composite, ceramic or metal material on the insulating pad. A set of terminal conductors is connected to the resistant layer and the completed resistance is closed in the protective coating. The materials used to produce chip resistors usually adhere to most international safety standards and contain a minimum amount of lead, cadmium and hexavalnt chrome.
There are two of the most widely used chip resistor are the only resistance and fields of chip resistance. The only resistance is the passive component of the set value and the field of resistance consists of several resistors of identical values V isDNOM package. Individual resistors have one set of end wires, while the field of chips resistance is in-line packages with several pins representing one common pin and one for each field resistance.
There are several categories of chips resistor, all of which take care of the range of application requirements. These include the purpose of the proposed source of energy, telecommunications, high frequency, current sensing, automotive, medical and air components. Trade union resistors may also include unique features such as integral coolers, water cooling equipment, focal shelves or coatings and non -inductive shielding.
