Reasons for The Increasing Importance of Circuit Protection Components
In daily life, electronic products are everywhere, and circuit protection has become increasingly important. To make circuits safer, engineers are constantly studying the safety and reliability of products. The main reasons for the increasing importance of circuit protection components are as follows:
(1) With the demand for the development of electronic products, the functionality (integration) of ICs is also becoming stronger, and their "value" is naturally becoming more noble, so it is necessary to strengthen protection.
(2) To reduce power consumption, reduce heat generation, and extend service life, the working voltage of semiconductor components and ICs is getting lower and lower. According to statistics from the American Semiconductor Industry Association, the current working voltage is around 1.5V, which will decrease to a lower level in the following years. Therefore, its ability to withstand overcurrent/overvoltage needs to adapt to new protection requirements.
(3) There are more and more mobile electronic products, such as mobile phones, iPads, laptops, digital cameras, jukeboxes, etc. These electronic products require battery components as power sources and protective components must be equipped in both the battery components and chargers.
(4) In modern luxury cars, there are more and more electronic devices equipped, and the working conditions are worse than ordinary electronic products, such as the rapidly changing driving conditions and environment of the car, and the large instantaneous peak voltage generated when the car starts. Therefore, in the power adapters provided for these electronic devices, it is generally necessary to install both overcurrent and overvoltage protection components simultaneously.
(5) Many power products/electronic products require lightning strikes and interference between power and telephone lines to protect normal communication and user safety. So, with the development of power/electronic products, the demand for overcurrent/overvoltage protection components is on the rise.
