Operating Temperature

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

-20°C~150°C TJ

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.

Motor Type

Stepper

Ambient Temperature Range High

This varies from person to person, but it is somewhere between 68 and 77 degrees F on average. The temperature setting that is comfortable for an individual may fluctuate with humidity and outside temperature as well. The temperature of an air conditioned room can also be considered ambient temperature.

85°C

Motor Type - Stepper

Bipolar

Step Resolution

Servo motor resolution is determined by feedback device of motor. I.e. 1000 PPR (pulses per revolution) quadrature encoder yields 1/4000 revolution resolution because 1000 PPR equals 4000 counts per revolution after standard 4X decoding.
