Arcol, 4Ω 25W Aluminium Chassis Mount Resistor HS25 4R F ±1%
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 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.
Tolerance is the percentage of error in the resistor's resistance, or how much more or less you can expect a resistor's actual measured resistance to be from its stated resistance. A gold tolerance band is 5% tolerance, silver is 10%, and no band at all would mean a 20% tolerance.
There are 5 types of mode of operation, Electronic CodeBook (ECB), Cipher Block Chaining (CBC), Cipher feedback (CFB), Output Feedback (OFB), Counter Mode (CTR).
