   Technology / Construction       
   Your choices are...         
   Carbon Composition       Carbon-composition resistors consist of powdered carbon, an insulating material, and a resin binder. Their resistance value is determined by the ratio of powdered carbon to insulating material. Carbon-composition resistors usually have a precision of no greater than 5%. This means that a 100-ohm resistor can range from 95 to 105 ohms in actual value. 
   Carbon Film       Carbon-film resistors are relatively inexpensive and readily available. They have resistance values within ±10% or ±5% of their marked or nominal value. 
   Cermet       Cermet devices are made of cermet, a composite that consists of ceramic and metallic materials. They are often used in high-temperature applications. 
   Ceramic Composition       Ceramic-composition resistors are solid-body devices made of a high-temperature, ceramic resistive material. They have bonded metal contacts. The construction of ceramic-composition resistors concentrates nearly all of the component mass into the resistive element, resulting in a rugged device with high-energy capacity. 
   Coiled Wire Resistor       Coiled wire resistors are made by coiling wire on an insulated core. 
   Edgewound Resistor       Edgewound resistors are made of high-power wire that is wound on edge to form a helical, resistive element. 
   Grid Resistor       Grid resistors consist of high-power wire that is formed into grid. Several grids are then fitted into an enclosure. Grid resistors can withstand both high power and high current. 
   Metal Alloy       Metal-alloy resistors contain metallic elements. Varying these elements can alter the alloy's properties. 
   Metal Film       Metal-film resistors are produced by depositing a resistive element on a high-grade, ceramic rod. The metal film’s resistive element may be carbon, nickel chromium; or a mixture of metal and glass, or metal and metal oxide. The precise resistance is achieved by removing part of the metal film in a spiral pattern around the rod. Typically, the tolerance is within ±2% or ±1% of the nominal value. When a tolerance of 1% is achieved, a 100-ohm, 1% resistor falls in the range of 99 to 101 ohms. 
   Metal Foil       Resistors are made of metal foil. 
   Metal Oxide       Metal-oxide resistors are similar to metal-film resistors. Although there are some differences between these resistor types, none affect their use in simple circuits. 
   Ribbon Resistor       Ribbon resistors are power resistors made with metallic, ribbon-like elements. These ribbon elements are formed by folding a strip of metal back and forth. 
   Tantalum       Resistors are made of tantalum, an element that is also used in capacitors. Tantalum resistors are used in audio applications. 
   Thick Film       Thick-film resistors are made by stenciling a resistive metallic paste or ink onto a base in a process similar to silk screening. Usually, this resistive material is considered to be proprietary. 
   Thin Film       Thin-film resistors are formed by vapor-deposition of a thin layer of resistive material onto a base. They are trimmed to a specific value by lasering or sandblasting. 
   Wirewound Resistor       Wirewound resistors are made by winding thin wire onto a ceramic rod. Highly-accurate devices are used in multimeter, oscilloscopes and other measuring equipment. Wirewound resistors that can pass large currents without overheating are used in power supplies and other high-current circuits.

   Mounting / Packaging       
   Your choices are...         
   Surface Mount (SMT / SMD)       Surface mount technology (SMT) adds components to a printed circuit board (PCB) by soldering component leads or terminals to the top surface of the board. SMT devices (SMD) have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads. 
   Bolt-on (Chassis)       Chassis mounted devices bolt onto or within a structure’s supporting frame, typically in a metal-to-metal configuration for better heat dissipation. Some chassis types are designed to be mounted within a rack. 
   Panel Mount       Panel-mounted devices have a threaded bushing which surrounds the shaft. 
   Through Hole       Through hole technology (THT) mounts components on a printed circuit board (PCB) by inserting component leads through holes in the board and then soldering the leads in place on the opposite side of the board. 
   Axial Leads       Axial leads extend from the ends and along the axis of the resistor. They do not extend from the sides.   
   Gull Wing Leads       Gull-wing leads are used widely because they are relatively inexpensive to mold and form. Gull wings are flexible and can withstand thermal expansion and contraction. It is easy to inspect the integrity of gull-wing leads to circuit-board solder connections. 
   J-leads       J-leads are popular because they use less PCB real estate than gull wing leads; however, the J-lead to board solder connections are hidden from inspection and the leads are more difficult to form.

   3725       The package dimensions are 0.375" × 0.25" (9.5 mm × 6.3 mm). 
   SOIC       Small outline integrated circuit (SOIC). 
   SSOP       Shrink small outline package (SSOP). 
   SC-70       SC-70 is one of the smallest available IC packages. It is used in cellular phones, PDAs, electronic games, laptops and other portable and hand-held applications where space is extremely limited. 
   SOT23       SOT23 is a rectangular, surface mounted, small outline transistor (SOT) package with three or more gull wing leads. SOT23 features a very small footprint and is optimized for the highest possible current. Because of its low cost and low profile, SOT23 is used in home appliances, office and industrial equipment, personal computers, printers, and communication equipment.
