This article will continue to introduce the FUZETEC PPTC fuses surface adhesive and battery fuses series, to help users more fully understand the characteristics and application scenarios of these products, so that they can make the right decision when selecting.
Surface adhesive PPTC fuses are popular because of their small size, lightweight, and easy integration on circuit boards. The main series include FSMD2920, FSMD2016, FSMD1812, FSMD1210 and FSMD1206. These numbers usually represent the size of the fuse, such as FSMD1206 indicating a fuse with a length of 1.2mm and a width of 0.6mm. In the selection, the user needs to choose the appropriate size according to the space and layout requirements of the circuit board.
In addition, parameters such as the working current, rated voltage and rated current of surface adhesive PPTC fuses are also important factors to be considered when selecting. Users should choose fuses with appropriate parameters according to the actual needs of the equipment and the working environment to ensure that they can provide effective overcurrent protection.
Battery fuses are PPTC fuses specifically designed for battery protection. It can quickly cut off the current and protect the battery from damage when the battery is overcharged, overdischarged or short circuit. Battery fuses typically have a low internal resistance and a high current rating to ensure minimal impact on the battery under normal operating conditions.
When selecting battery fuses, users need to pay attention to the following aspects:
Different types of batteries (such as lithium-ion batteries, nickel-metal hydride batteries, etc.) have different working characteristics and safety requirements, so it is necessary to choose a matching fuse. The capacity of the battery will also affect the choice of fuses, and high-capacity batteries usually require fuses with higher current ratings. The lower the internal resistance, the smaller the impact on battery performance; The rated current needs to be selected according to the actual working current of the battery, both to ensure that the current can be cut off in time under abnormal circumstances, and to avoid misoperation during normal operation. Battery fuses may generate a certain amount of heat during operation, so it is necessary to ensure that they can work properly within the operating temperature range of the device.
