The world's first chip square brick resettable fuse

SMD square brick fuse is a ceramic body, the structure of brass gold-plated/silver-plated caps on both sides, SMD package, automatic mass production. The voltage can be 32V 63V 72V 125V 250V 300V 350V 400V 450V 500V 550V 600V 650V 700V 750V 800V 850V 900V 950V 1000V, the current can reach up to 100A, the size is mainly 0603 (1.6*8.8mm) /6125/2410(6.1*2.5mm), 1025/1032(10.2mm*3.2mm), 4512/1245 (12.4*4.5mm), 2050(20.5*5.06*5.06mm), 3263(32*6.3*6.3mm), breaking capacity can reach 1000A, safety certifications include CCC, CQC, UL, CUL, PSE,VDE, TUV, KC, etc., environmental certifications include ROHS, REACH, halogen-free, etc.,but the fly in the ointment is that it is a one-time fuse, Not recoverable.

SMD Resettable fuse, the main material is high molecular polymer PTC, the resistance value changes with the change of temperature, which is proportional. Sizes are 0402, 0603, 0805,1206, 1210, 1812, 2018, 2920. Low internal resistance, recoverable, also known as 10,000-

time fuse, when the circuit fails, the fuse fuses to form an open circuit, and the fuse returns to normal resistance when the circuit returns to normal form a pathway. Safety certifications include CQC, UL, CUL, TUV, etc., and environmental certifications include ROHS, REACH, halogen-free, etc., but they are limited by structure and volume, and the current and voltage are relatively small, which cannot reach the parameters of the chip square head fuse.

Therefore, our company has developed a new product that can combine the characteristics of the two products - SMD square brick resettable fuse, which has the structure of the chip square brick fuse to achieve high voltage and high current, and also has the resettable fuse of the resettable fuse. Characteristics, the current production specification range is 500mA~15A, and the voltage is 250V. Next, we will gradually cover all voltages and currents synchronously to meet the needs of different customers. Consultation and sample testing are welcome.

Dongguan Amfort Electronics is a comprehensive company integrating R&D, manufacturing and sales. It adopts advanced management system, imported high-precision automatic production machines, strong R&D team, skilled technicians, and many international certifications to

ensure that every The manufactured fuses are all qualified and reliable. We will continue to work hard to improve product quality and be close to world-class brands. Welcome to consult.
