Inrush current limiters (ICLs) are electrical components designed to reduce large inrush currents, which can be hazardous and cause circuit overloads. The MF72-005D20 is an inrush current limiter with a wide range of applications and various features. This article discusses the application field and working principle of MF72-005D20.

The MF72-005D20 is an inrush current limiter designed to protect circuits and surge suppressors from damage caused by large inrush currents. It is used in a variety of industries for various applications, such as automotive, aerospace, home electronics, industrial electronics, and telecommunications. The MF72-005D20 is designed to be durable and reliable, with its long-term mechanical and environmental performance rated at over 20 years. The device is also compatible with various power circuits and can be used in a wide range of operating voltages from 0-26V.

The working principle behind the MF72-005D20 inrush current limiter is based on the principle of self-limiting non-linear resistance (SLNR). SLNR technology uses an electronic circuit with the ability to continuously adjust its own resistance according to input current and voltage. On the MF72-005D20, the SLNR circuit is designed to limit the inrush current to a protected circuit by modulating its own resistance. During normal operation, when the input current is below a set threshold, the SLNR circuitry remains non-conductive, allowing for normal operation of the circuit. However, when the input current exceeds the set threshold, the SLNR circuitry becomes conductive and adjusts its own resistance, limiting the inrush current.

The MF72-005D20 is designed with adjustable limiters, allowing users to adjust the level of protection for different levels of inrush current. The device also features a wide operating temperature range from -40 to 125°C, making it suitable for use in a variety of environments. The MF72-005D20 also has numerous safety features, such as a slim surface-mount design, which minimizes the risk of electrical shock. Additionally, the device is RoHS compliant and UL listed, providing assurance that it is safe for use in various settings.

In conclusion, the MF72-005D20 inrush current limiter is a versatile and reliable device with a wide range of applications. It is designed to protect circuits and surge suppressors from damage caused by large inrush currents and features a self-limiting non-linear resistance (SLNR) circuit which adjusts its own resistance according to input current and voltage. The device is also compatible with various power circuits, features adjustable limiters, and has numerous safety features.
