MF-R700-0-99

PTC Resettable Fuses provide protection for low-voltage products from short circuits and overloads. The MF-R700-0-99 is a maximally resettable fuse designed for applications in fields such as consumer electronics, medical equipment, automotive, and industrial control.The MF-R700-0-99 is specifically designed to provide the highest level of protection for products in these fields. It features an optimized time-delay that allows for resetting in the event of an overload situation. The fuse also features a high-current rating which makes it suitable for use in high-current applications. Additionally, the fuse is RoHS compliant and certified to the latest electrical safety standards.The main working principle behind the MF-R700-0-99 is the use of a Positive Temperature Coefficient (PTC) thermistor. The thermistor is a special type of resistor that has a very low resistance when cool and a high resistance when hot. The heat generated when a short circuit or an overload occurs, causes the thermistor to get hot, which increases its resistance. This increase in resistance limits the current flowing through the circuit and prevents it from becoming too high. The limiting of the current prevents the circuit from becoming damaged from the overload.Once the thermistor has cooled down, it returns to its low resistance state allowing normal operation. The character of the resetting is defined by the user and it can be configured from 1 second to several minutes. This allows the user to choose the most appropriate reset time for the application.The MF-R700-0-99 is designed to provide protection against short circuits and overloads. The thermistor used in the fuse is specially designed to have a very low resistance when cool, and a high resistance when hot. This provides the temperature sensitivity needed for the fuse to protect the circuit from short circuits and overloads. Additionally, the user can configure the reset time to ensure the best protection for the application. As a result, the MF-R700-0-99 provides reliable protection for low-voltage applications in fields such as consumer electronics, medical equipment, automotive, and industrial control.
