I. ESR overview of equivalent series resistorsESR is the abbreviation for the equivalent series resistance, the "equivalent series resistor". The ideal capacitor itself will not have any energy loss, but in fact, because the material that makes the capacitance has a resistor, the capacitance of the insulating medium is lossy. This loss is external and behaves like a resistor in series with a capacitor, so it is called an "equivalent series resistor". Some capacitors also have an ESR value (equiv

households with unique functions, greatly shortening the cooking time and saving energy, you can also make a general pot that cannot be made. However, some household accidents that cause improper use and damage and destruction often occur. Here, we summarize the nine taboos in use, hoping to attract your attention.Avoid improper use. The first is to purchase a pressure cooker selectively. Be sure to select a pressure cooker with a brand name, manufacturer, specification, and qualified quality.

sapphire, with IPhone6 mobile phone home Key's Touch ID protects the glass material. Sapphire is considered to be the hardest transparent material besides diamonds, and it is very good to prevent and scratch. 　　Sports version Sport 　　The Movement version Sport uses the anodized aluminum shell, this material is bigger than the standard alloy hardness 60%, It is also the Apple three intelligent watch model the lightest. Instead of using an expensive

quality, and higher costs, so we are currently very difficult to see the use of copper to produce heat sinks. Again in copper is iron and aluminum, these two are very popular metal, but both horizontal comparison, you will find iron rust, texture hard, difficult to process, quality and other weaknesses, and aluminum is not such trouble, so aluminum becomes the b

catheter, plastic catheter, or other protection with different Grounding Impedance. Therefore, there is only one solution to achieve permanent ground-to-ground performance: grounding with multiple layers of aluminum foil on all core wires. Aluminum Foil protects the fragile twisted pair core wires and creates a balance environment for UTP cables. This means that the FTP cable-based shielding solution is **

I must first declare that this article only speaks on personal experience and cognition, because I have not been in the circuit board manufacturing industry, for more information about the hardware, software, and flash on the circuit board, I have asked the relevant circuit board about the following for many years. If there is any error, please leave a message.There are a lot of friends who are working in the later assembly plant. The hard gold and soft gold on the circuit board have been unclea

whether the color, thickness, and gloss of the pipe are marked with trademarks, specifications, temperature, pressure, production batch number, production date, and actual place of origin, the aluminum-plastic tube also depends on the thickness and uniformity of the aluminum layer. Second, check whether there is a health permit. Water pipes without a health permit cannot be used for drinking water pipes.②

The chassis is strong to the stability of the host has a great impact, especially hard disk, optical drive such storage equipment, imagine if your chassis in a long time shaking state how to ensure safety. In general, a good chassis plate thickness should be at least one millimeter above, and the plate should be a special treatment of galvanized steel. Because galvanized steel plate with anti-static, not easy to rust and not easy to touch the advantages of fingerprints. There is also

Solid-State capacitors are all called: solid aluminum electrolytic capacitors. It differs from the ordinary capacitance (i.e. the liquid aluminum electrolytic capacitor) with different dielectric materials, liquid aluminum capacitor dielectric material as electrolyte, and the dielectric material of solid-state capacitor is conductive polymer.

don't need to change the code. It works in any case (assuming that all trash subclasses contain a builder to get a single double parameter). 1. Trash SubclassIn order to fit in with the prototype mechanism, the only requirement for each new subclass of trash is to include a builder in it that instructs it to get a double parameter. The "reflection" mechanism of Java 1.1 can be responsible for all remaining work.The following are different types of trash, each of which has its own file, but it i

heat dissipation effect. This type of radiator generally uses a combination of copper base and Aluminum Fins. The main advantage of this combination is the application of the fins, which greatly enhances the actual heat dissipation area. At the same time, because the fin and the base are also connected through welding, the direction of the fin is not too complex, usually made into a straight line air duct, in combination with a turbine fan with a la
