sony bravia tv fuse location.Discussion on the Testing Method of Chip Fuses
We know that there are many series of fuses in the electronic component market, including patch fuses. This series of fuses is commonly used in factories, with few being used by individual users. But what should we pay attention to when testing patch fuses? Today, editor Dai Liang, let's take a look together. Firstly, The detection method for patch fuses is recommended to be based on the following aspects: normal current, fusing current, open circuit voltage, short circuit current, impulse current, and ambient temperature. 1. Normal current: Firstly, we must know the normal current flowing through the fuse in the circuit used. Usually, we need to pre-set a derating amount and choose according to the following principle: the normal current must be less than the product of the rated current and the derating coefficient. 2. Fusing current: According to UL specifications, the fuse should quickly fuse at twice the rated current. But in most cases, to ensure reliable fusing, we recomm
