NCE3013J_NCEP30T19G Introduction

The resistance of this current path is called the internal resistance of the MOS tube, that is, the on-resistance. The size of this internal resistance basically determines how much on-current the MOS tube chip can withstand (of course, it is related to other factors, such as thermal resistance). The smaller the internal resistance, the larger the current (because the heat is small).

So the stability of the tube is inseparable from the manufacturing process, and poor workmanship may result in the inconsistency of the parameters of these small tubes. Their various switching actions are almost the same. Of course, when they burn out, there must be a small tube that can't bear it first.

The company's founder, Felix Zandman, is a scientist, inventor and entrepreneur with 71 patents, author of four books and many papers, winner of the American Electronics Industry Medal of Honor, the French Medal of Honor and many other awards. Founded by Dr. Felix Zandman in 1962, Vishay has grown into a Fortune 1000 company listed on the New York Stock Exchange from his own $4,000 savings and funding from his cousin Alfred P. Slaner. .

There is parasitic capacitance between the three pins of the MOS tube, which is not what we need, but is caused by the limitation of the manufacturing process.

For 17 months without the light of day, Zandman's uncle taught him algebra, trigonometry, geometry and physics. Zandman was born in Poland in 1928. During the Nazi Holocaust in World War II, Zandman was taken in by an old housekeeper whom Zandman's grandmother had rescued. He and four others hid under the housekeeper's floor for 17 months before they were able to escape the Holocaust. . In 1956, Zandman immigrated to the United States and founded Vishay in 1962. . It can be said that what Zandman learned during those darker days laid the groundwork for him to start Vishay. After the war, Zandman immigrated to France, earning degrees in Mechanical Engineering, Applied Mechanics and General Physics, and a Ph.D. in Mechanical Physics at the Sorbonne University in Paris.

These two factors make Vishay's MELF resistors the choice for high-end audio applications with low noise requirements. Vishay's MELF resistors are produced using an advanced vacuum sputtering process that deposits a layer of a proprietary nickel-chromium alloy of extremely high microstructural quality on a very smooth aluminum substrate in an ultra-high vacuum chamber. This sophisticated internal structure provides the ideal foundation for low-noise performance, which is further enhanced by the cylindrical shape of the resistor. With a 3.14 times larger surface area than flat chip resistors for the same pad size, these devices can produce much higher aspect ratios, resulting in very low field strengths along the resistors. Be aware that the local electric field strength is the main source of current noise. Compared to thick film resistors, this typically provides a spectral density improvement of about -40 dB V/Hz, a figure of about -10 dB V/Hz in the case of thin film resistors, as shown in Figure 2.
