The best value TV set in 2017 is the best value for money!

When winter comes to spring, spring is a romantic season. I wonder if there are many pairs of affectionate men and women. There is a home to live in. Even though housing prices are soaring today, not all people can have a “living place”. But...the poor people have more (jiu shi wo) and the rich have more (fan zheng bu shi wo). When a monk marries, the parents behind himself want to help them get married... In short, for a long time... When you have a home, you must have an electric appliance.
As one of the family's important electrical appliances - TV, naturally have to choose some, the price has been so expensive, for the hard to pay for the room every month, of course, to buy a value smart TV, 3,000 yuan, not expensive is not cheap, just it is good.
So, about 3,000 yuan smart TV, in the end some of the more quality and quality protection? If you are cheap and good, you have to pick more.

TO-220 package

TO-220 Transistor Outline Package is a type of in-line package often used in high-power transistors and small and medium-sized integrated circuits.

It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also connects to the pins of the package shell with wires through the contacts on the chip, and these pins pass through the wires on the printed circuit board. Connect with other devices to realize the connection between the internal chip and the external circuit.Because the chip must be isolated from the outside world to prevent impurities in the air from corroding the chip circuit and causing electrical performance degradation. On the other hand, the packaged chip is also easier to install and transport.

TO-220 package is a kind of in-line package that is often used for fast recovery diodes. TO-220AC represents a single tube with only two pins and only one chip inside.

The diodes are packaged in TO-220AC and can be used in switch mode power supplies (SMPS), power factor correction (PFC), engine drives, photovoltaic inverters, uninterruptible power supplies, wind engines, train traction systems, electric vehicles and other fields.
