EMI is an abbreviation of Electro Magnetic Interference. The word describes the negative effect caused on peripheral equipment by an electronic device, and it is also called emission. EMI consists of conductive noise that leaks to a power source, and radiation noise that is emitted as electromagnetic waves. For details, refer to Application Manual Chapter 10.
FAQ Categories: Description of Terms
-
What is EMI?
-
Is there any quality difference between products made in Japan and those made overseas?
Fuji Electric Corp. of America enforces the same quality standard for product management at all locations, regardless of where the manufacturing sites are.
-
Where are Fuji semiconductor products manufactured?
The semiconductor products of Fuji Electric Corp. of America are manufactured at its six sites in Japan (including Matsumoto Factory, Yamanashi Factory, Fuji Electric Power Semiconductor Co., Ltd., and Fuji Electric Tsugaru Semiconductor Co., Ltd.), and three overseas sites (Fuji Electric (ShenZhen) Co., Ltd., Fuji Electric Philippines, Inc., and Fuji Electric (Malaysia) Sdn. Bhd.).
-
What is the diode’s I2t?
I2t is a Joule-integral for overcurrent allowed within the range that does not result in element destruction. Overcurrent is defined in one cycle at commercially restricted half-waves (50, 60 Hz).
-
What is a NTC?
NTC (Negative Temperature Coefficient Thermistor) is an electronic component whose resistance decreases while the temperature increases.
-
What is the difference between Tj(max) and Tj(op)?
The maximum allowable temperature for the chip during conventional continuous operation is specified in Tj(op). Please ensure the maximum chip temperature stays at or under Tj(op) during conventional continuous operation. The maximum allowable temperature for a chip during short-term overload or abnormal operation is specified inTj(max).
-
What is the case temperature (Tc)?
Case temperature (Tc) is the temperature on the module copper base surface right under a semiconductor chip where the temperature is the highest.
-
What is the junction temperature (Tj)?
Junction temperature is the temperature at joints on a semiconductor chip.
-
What is the meaning of each item in the IGBT data sheet?
Refer to the description of terms in Application Manual Chapter 2-1.
-
How do I read IGBT module model types?
Refer to “Part numbers” in the Semiconductors General Catalog.
