Performance Specifications




   Resistance Range
 
     The device's resistance range. 
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Tolerance
 
     Resistance tolerance is usually expressed a percentage.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Temperature Coefficient (TCR)
 
     Temperature coefficient of resistance (TCR) measures the rate at which the nominal resistance changes as a function of temperature. TCR is expressed in parts per million (ppm) per degree Celsius (C), or ppm/C.

   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.
