Question 1

What is the Surface Mount ?

Accepted Answer

having leads that are designed to be soldered on the side of a circuit board that the body of the component is mounted on.

Question 2

What is the Operating Temperature ?

Accepted Answer

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.

Question 3

What is the Packaging ?

Accepted Answer

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.

Question 4

What is the Part Status ?

Accepted Answer

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

Question 5

What is the Terminal Form ?

Accepted Answer

Occurring at or forming the end of a series, succession, or the like; closing; concluding.

Question 6

What is the Terminal Pitch ?

Accepted Answer

The center distance from one pole to the next.

Question 7

What is the Max Supply Voltage ?

Accepted Answer

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

Question 8

What is the Min Supply Voltage ?

Accepted Answer

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

Question 9

What is the Nominal Supply Current ?

Accepted Answer

Nominal current is the same as the rated current. It is the current drawn by the motor while delivering rated mechanical output at its shaft.

Question 10

What is the Quiescent Current ?

Accepted Answer

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

Question 11

What is the Synchronous Rectifier ?

Accepted Answer

Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).

Question 12

What is the RoHS Status ?

Accepted Answer

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
