Mounting Type

Panel Mount

Resistive Material

The resistive material is a combination of a Ceramic material and a Metal, and therefore these resistors are also referred to as Cermet. Just as with carbon film, the resistance value is adjusted by cutting a spiral pattern in the film. This can be done with an abrasive or a laser.

Packaging

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

Bulk

Tolerance

±15%

Temperature Coefficient

The resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. This factor is represented by the Greek lower-case letter “alpha” (α). A positive coefficient for a material means that its resistance increases with an increase in temperature.
