PTC Resettable Fuses are resistor-like devices that are used to limit current in an electric circuit. The RUSBF110-AP is a reverse-polarity protection and overcurrent protection device for high-current applications. It is designed to provide reliable circuit protection against overcurrents and surges in industrial, automotive, telecom, and networking applications.

The RUSBF110-AP is a single-in-line, reverse-polarity-protected, overcurrent-protected, PTC resettable fuse. It is designed to limit overcurrents in an electric circuit while providing reliable protection against reverse-polarity connection. It features a unique, self-correcting system of active bi-directional protection, which continually monitors and limits the forward and reverse currents.

The RUSBF110-AP can be used in various applications, including automotive, industrial, commercial, data and telecom, and networking applications. Its unique design ensures reliable protection against overcurrents, short circuits, surges, reverse polarities, and a wide range of related causes.

The RUSBF110-AP works on the principle of self-resetting circuitry. When current passes through the device, the associated reactance value increases. When the current level exceeds the trip level, the fuse will open, which will reduce the current. After the duration time has passed, the reactance value will decrease, and the fuse will reset. During the reset process, the overcurrent protection is inactive and the device will continue to limit current through the main fuse.

The RUSBF110-AP features a built-in thermistor that is used to detect and limit the temperature of the device. When the temperature exceeds the trip level, the device will open and limit the current. The fuse also has a high-voltage withstand capability of up to 18 volts, which ensures reliable overcurrent protection. Additionally, it has a reverse current blocking capability, which prevents reverse currents from damaging the device.

The RUSBF110-AP is available in various package configurations, including through-hole and surface mount configurations. It is designed for use in harsh environments such as high-temperature, high-humidity, and high-vibration applications. It features a low profile, which allows it to be easily installed even in tight spaces. Additionally, the device is RoHS-compliant and AEC-Q101 qualified, which ensures it meets the highest quality standards.

In summary, the RUSBF110-AP is a reverse-polarity-protected, overcurrent-protected, and PTC resettable fuse. It is designed to limit overcurrents in an electric circuit while providing reliable protection against reverse-polarity connection. It is suitable for use in various applications, including industrial, automotive, data and telecom, and networking applications. Its unique design ensures reliable protection against overcurrents, short circuits, surges, reverse polarities, and a wide range of related causes. The device is highly reliable, and is available in various package configurations.
