NCE3080IA_NCEP4040Q Introduction

There are many well-known brands in the electronics industry, each brand is like a person's name, and its origin and naming have its own unique style. Their success today is due to the founders. When naming the company, the founders incorporated their nostalgia for the past and expectations for the future. A simple name with many untold stories behind it... .

MOS tubes like NCE80H12 convert the DC power in the battery into AC power when the electric vehicle is running normally, thereby driving the motor to run.

Why did Felix Zandman name his company Vishay? Because his grandmother was born in Vishay, the name of a small Lithuanian village in honor of family members who were killed in the Holocaust. Felix Zandman wrote in his memoirs , "A lot of people think the name sounds weird, but for me, every time I hear it, I think of my grandmother, the power she gave me and others, the things that were erased forever in Eastern Europe. Jewish community.

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.

For fine-tuning of Vantam's analog signal paths, including low-pass filters [LPF], negative feedback circuits [NFB], preamp ICs, IV converters, and headphone amplifier circuits, VentureCraft previously relied on thick carbon-containing diaphragms type resistor. . Last year, VentureCraft began specifying Vishay products after learning that Vishay's thin-film MELF resistors (shown in Figure 1) could provide excellent sound quality. Over the past few years, the company has turned to thin-film technology as it focuses on providing audio performance differentiation.
