RUSBF075-AP Circuit Protection

PTC Resettable Fuses are an innovative solution for overcurrent protection in electronic products and equipment. As the name suggests, these fuses are designed with a polymeric thermistor that can detect and respond to a current overload condition. The device will then open the circuit until the current returns to a safe level, and then re-close the circuit. This allows the fuse to continuously protect against overcurrent and helps reduce the risk of catastrophic damage to the device from surprize power surges or overloads.

The RUSBF075-AP is a PTC resettable fuse designed to protect a variety of electronic applications. This device offers superior thermal protection with a fast response time of 1 second. It has an operating current of 0.75 Amps (A), a maximum power dissipation of 1W, and a maximum tripping current of 7.5 A. Due to its small size, the device is especially suitable for use in portable electronic devices such as cell phones, tablets, laptops, etc.

The working principle of the RUSBF075-AP is as follows: when the current flowing through the fuse exceeds the maximum limit of 7.5 A, the polymeric thermistor within the device will heat up and expand, breaking the electrical connection. This will open the circuit and protect the device from further damage. Once the current drops to a safe level, the thermistor will cool down, and the circuit will re-close. This allows the fuse to continuously protect the device from overcurrent without needing to be replaced.

The RUSBF075-AP offers a variety of features and benefits that make it an ideal choice for a wide range of applications. It is especially well suited for mobile applications, providing superior thermal protection and fast response times. The device is also RoHS compliant and UL Recognized, making it safe and reliable in even the most demanding environments.

In summary, the RUSBF075-AP is an innovative PTC resettable fuse that offers superior protection in a variety of electronic applications. The device’s fast response time and RoHS compliance make it a reliable and safe solution for overcurrent protection.
