The Maximum Operating Temperature is the maximum body temperature at which the thermistor is designed to operate for extended periods of time with acceptable stability of its electrical characteristics.
The voltage level by which an electrical system is designated and to which certain operating characteristics of the system are related.
the angle at which a display can be viewed with acceptable visual performance.
Current which flows upon application of forward voltage.
the amount of voltage needed to get current to flow across a diode.
Power consumption is the amount of input energy (measured in watts) required for an electrical appliance to function. This is opposed to power output which is a measure of the level of performance, of a heat pump for example.
the measure of the perceived power of light.
IP (or "Ingress Protection") ratings are defined in international standard EN 6529 (British BS EN 6529:1992, European IEC 659:1989). They are?used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies?(tools, dirt etc) and moisture.
