In response to HMD's rumor of launching a Nokia cell phone using a Carl Zeiss lens, the HMD public relations team said in an interview with the media that HMD will not use Carl-Zeiss optics on existing Nokia Android phones. The HMD team stated that the HMD official only announced the Nokia 3, Nokia 5 and Nokia 6, and the Nokia 3310, so Carl Zeiss was only used as an option for future Nokia Android flagship products.
The Nokia 3310 (2017) comes pre-loaded with Snake Games developed by Gameloft. When the media asked if HMD would pre-install the same games for other S30+ devices, HMD stated that there is currently no such plan, and the HMD team also reminded that it was developed by another company. Snake Xenzia games are pre-installed in the Nokia 150.
The HMD team also confirmed that Nokia 3, Nokia 5, and Nokia 6 all support VoLTE, but they declined to confirm whether an operator supports VoLTE capabilities of the three smartphones, such as Indian mobile operator Reliance Jio. The HMD team stated that before the specific confirmation, it needs to pass the official test.
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.
