General Specifications
   Potentiometer Type       
   Your choices are...         
   Standard Potentiometer       Standard potentiometers are mechanical devices in which the output resistance is set by a shaft. 
   Digital Potentiometer       Digital potentiometers are three-terminal resistors with an adjustable center connection. To set the output resistance, a digital signal is sent through an electrical interface. 
   Rheostat       Rheostats are potentiometers in which a third, "wiper" terminal is shorted to one of two fixed terminals. This wiper terminal has a resistance which varies with its position. The two fixed terminals are connected by a fixed resistance. 
   Trimmer       Trimmer-style potentiometers are factory-set devices that require infrequent adjustments. They feature a slotted, actuator style and can be adjusted with a special tool or screwdriver. 
   Other       Other unlisted or proprietary potentiometers. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Potentiometer Category       
   Your choices are...         
   Industrial Grade (Enclosed)       The potentiometer is protected by an enclosure, usually one that is NEMA-rated. Most industrial-grade potentiometers are gear-driven and have connector outputs. They resist the ingress of dirt and dust, and last longer than unenclosed potentiometers. 
   Discrete Board Component       Devices are discrete, board-level components.

   Actuator Configuration:       
   Your choices are...         
   Single Turn       The shaft rotation is limited to less than or equal to 360 degrees. 
   Multiturn       The shaft can be rotated multiple times. Some have as many as 15 or 20 turns from stop to stop. 
   Slide       Instead of rotating a knob, the user moves a handle, sliding the internal-contact mechanism linearly along the length of the potentiometer. 
   Other       Other unspecified configurations.

Physical Specifications
   Technology / Construction       
   Your choices are...         
   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. 
   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. 
   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. 
   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. 
   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. 
   Other       Other unlisted, specialized, or proprietary configurations.

   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. 
   Radial Leads       Radial leads extend from the sides instead of from the ends. 
   Screw Terminals       Terminals are designed for screw mounting on a circuit board. 
   Tab Terminals       Terminals are designed for direct mounting on a circuit board.  
   Other       Other unlisted, specialized, or proprietary configurations.
