FHF540 field effect tube can avoid problems such as unstable speed regulation of electric sewing machine

With the market’s pursuit of craftsmanship, quality, and labor costs, many garment manufacturers have begun to switch to electric sewing machines. When purchasing sewing machines, garment factories obviously pay more attention to whether the speed is effective and whether it will lead to needle removal. Important reference. The electric sewing machine is controlled by a motor, and the motor uses a MOS tube to control the frequent conduction of the motor’s power supply voltage, so that the motor can adjust its speed by changing the effective value of the DC voltage of its power supply. Therefore, the manufacturer of the electric sewing machine The choice cannot be taken lightly. The IRF540N field effect tube is also the most used field effect tube in the motor speed control circuit of electric sewing machines.

The IRF540N field effect tube is also one of the most frequently used field effect tube models in the motor speed control circuit of electric sewing machines today.

Due to quality and technology issues, there are still many low-quality FETs on the market. And if the sewing machine manufacturer uses these inferior FETs to install on the circuit of the electric sewing machine motor, not only can the motor be unable to achieve precise speed regulation, it may also cause the motor to generate a large amount of heat due to excessive electric charge. These will not only affect As far as the performance and life of the motor are concerned, it will also cause product defects and other quality problems. In response to these problems of motor speed regulation, Feihong has developed this FHP540 / FHF540 low-voltage MOS tube, which can stably control the motor voltage.

Feihong Microelectronics’s FHF540 low-voltage MOS tube is an N-channel trench process MOS tube, and can also be used instead of 30N10 and IRF540N field effect tubes. It is mainly used for electric sewing machine motor speed control circuits and 72V→12V (5A) electric vehicles Voltage converter circuit.

The package form of FHF540 low voltage MOS tube is mainly TO-220/TO-251/TO-252, and the pin arrangement order is GDS, Vgs (±V) 25, VTH (V) 2-4, 28A, 100V, RDS (on ) = 37mΩ (max) @VGS = 10 V, and FHF540 low voltage MOS tube also has the advantages of low charge, low reverse transfer capacitance, fast switching speed, and low internal resistance.

Guangzhou Feihong Electronics has gradually expanded the use of MOS tube products to more Electronic fields through continuous research and development of new products, hoping to provide strong component protection for electronic product manufacturers. For example, this Feihong FHF540 low-voltage MOS tube is not only of high quality and low price, but also can replace the IRF540N field effect tube. In addition to providing free samples, Feihong can customize MOS tube products according to customer needs.
