DF3D18FU,LF Circuit Protection

DF3D18FU,LF or microFuse is a uniaxial bidirectional overcurrent protective device with an efficient protection function. It is a type of TVS(Transient Voltage Suppressor) diode, which is widely used in the field of computer, communication, automobile and consumer electronics.

The working principle of DF3D18FU,LF is based on its ability to quickly suppress the voltage reversal. It has two terminals-anode and cathode- and when excessive voltage is detected, an electric bridge caused by the breakdown of the pn junction is formed between the cathode and anode. This leads to the conversion of the excessive voltage to heat, which is then dissipated safely.

DF3D18FU,LF microFuse can be used in various electronic applications due to its low capacitance, fast turn-on time and low power dissipation. It can be used in the electronic devices such as:

• Uninterruptable Power Supplies(UPS)
• Solar energy panels and control systems
• Battery charging and discharging systems
• Communication equipment
• Automobile electronic systems and audio systems
• Consumer electronics(smartphones, laptops, etc).

DF3D18FU,LF microFuse has a superior current interruption capability. It is designed to have a very low thermal resistance for quick response time to overcurrent and overvoltage condition. It also has a higher insulation resistance for higher reliability. This makes it suitable for use in various industrial applications. Furthermore, this microFuse also has a very low leakage current for better energy efficiency.

DF3D18FU,LF microFuse is designed for overcurrent protection, so it can also protect against overvoltage. It has a working voltage range from 5V to 46V and operating temperatures ranging from -40℃ to 85℃. This makes it ideal for automotive, industrial and consumer applications.

DF3D18FU,LF microFuse is a very efficient protection device and has excellent performance in the field of computer, communication, automobile and consumer electronics. It can provide superior current interruption capability and high reliability in various electronic facilities and systems. Its low capacitance, fast turn-on time, low power dissipation, low thermal resistance and higher insulation resistance make it an ideal protection device for various applications.
