SMD Fuse
Surface mount SMD fuse (surface mount fuses)
Thin film patch fuse(Electronic fuse)
The thin film patch fuse uses FR4 as the substrate, copper tin alloy as the fuse, copper nickel tin alloy as the terminal, and a layer of liquid photosensitive solder mask ink on the outer layer of the fuse. The working temperature is usually up to 90 ° C. For the thin film of WIA aerial wiring, its working temperature can be increased to 125 ° C.
Ceramic SMD fuse
Ceramic SMD fuse are similar to films, except that the substrate is changed to ceramic to increase its temperature tolerance to 150 ° C. Surface mount fuses, due to their small size, are commonly used on control boards as overcurrent protection for power or signal lines. They are often defined as direct current, and some fuses may add alternating current voltage. Considering that the breaking capacity is inversely proportional to the voltage, if there are AC and DC voltages that exceed the specifications defined in the specification book in practical applications, the manufacturer can be contacted for specific communication. Through testing and verification, products with sufficient margin can increase their operating voltage specifications.
AECQ automotive grade surface mount fuse
The special situation of automotive applications requires corresponding fuses to withstand greater mechanical impact, higher temperature and humidity cycles, and longer service life. Currently, there is no unified standard for fuses, and various manufacturers are tightening testing conditions on the basis of standard materials. I claim that the high and low temperature impact frequency of FBelec SMD fuses has increased from the standard 100 cycles to 1000, and the double 85 high temperature and high humidity experiment has increased from 504 hours to 1000 hours. At the same time, a high temperature 1000 hour test item has been added, and high-frequency vibration has also increased to 2kHz. With the development demand of electric vehicles, automotive grade fuses will become increasingly abundant.
Nano fuse
The Nano fuse adopts the WIA aerial wiring method, similar to the tubular fuse that is usually in contact with it. From the structure, it can be seen that this product has a larger heat dissipation area and a wider arc extinguishing space, which brings benefits such as improved working voltage, working current, and breaking capacity.
Therefore, Nano fuses have expanded their application areas to power port protection for mains 220Vac or even 380Vac, replacing common radial and axial tubular fuses, which can reduce board space and make the power structure more compact.
Typical case sharing of SMD fuses
Emergency call system, over-current protection for boost and buck circuits
BMS application, AFE chip power port overcurrent protection
Fast charging, adapter power input protection
surface mount fuses is a new variety with relatively high technical content in the small fuse industry. Patch fuse can be divided into smd current fuse and smd self recovery fuse
