Resistors can be connected in series, why are diodes not suitable for series connection?

“In a static state, due to the different manufacturing deviations of the off-leakage current of each element in series, the element with the smallest leakage current bears the largest voltage, and even reaches the locked state. However, as long as the components have sufficient hold-up stability, there is no need to use grading resistors in the line. Only when components […]

Can Carbon Fiber Products Be Injection Molded?

First of all, carbon fiber products can of course be injection molded. There is no doubt about this, that is, it is similar to the molding of plastic products. In the production and machining of carbon fiber products, many processes are evolved from plastic products. Can carbon fiber products be Injection molding is actually related to the raw materials of […]

The cost of Mini LED-backlit displays is declining year by year, and it is expected to be more price competitive than OLED in 2022

With the introduction of Mini LED backlight technology into the 12.9-inch iPad Pro that Apple may release in 2021, the market has been hotly debated. According to the latest survey by LEDinside, a TrendForce, the production cost of Mini LED backlight displays is still higher than that of traditional LCD and OLED screens. It will decline at a rate of […]

Successful use of DC-DC buck/boost regulators in systems

The role of a DC-DC switching converter is to efficiently convert one DC voltage into another. High-efficiency DC-DC converters use three basic technologies: buck, boost, and buck/boost. Buck converters are used to generate low DC output voltages, boost converters are used to generate high DC output voltages, and buck/boost converters are used to generate output voltages that are less than, […]

Dry goods | Comparison between gateway redundancy protocol HSRP and VRRP technology

Comparison between Gateway Redundancy Protocol HSRP and VRRP Technology A redundancy protocol generally refers to a protocol that prevents network equipment from failing. Now there are three redundancy protocols: VRRP of IETF, HSRP of Cisco, and NSRP of JUNIPER. Today, let’s compare the differences between Cisco’s HSRP and Huawei and H3C’s VRRP protocols. HSRP: (Hot Standby Router Protocol) – Hot […]

This small device becomes the next battlefield for semiconductors

2021 was supposed to be the year of AMD’s explosion. Relying on the TSMC process, which is one generation ahead of Intel, AMD will continue to push Intel step by step. Bernstein Securities optimistically predicts that AMD’s market share in CPU this year will further surge from 10% in 2020 to 13%. It is expected that it will become the […]
