PTC (positive temperature coefficient) resettable fuses are among the most reliable and effective protection devices on the market. Designed for circuit protection, these devices allow circuits to return to their original operating conditions after experiencing short-circuit or overload conditions. The MF-R185-2-99 is a type of resettable fuse which features a PTC device which is capable of resetting itself after the fault condition is eliminated. The device is ideal for applications requiring reliable circuit protection and a small footprint.

The MF-R185-2-99 resettable fuse is based on a PTC device. This device is made up of two main components: the PTC and a contact switch. The PTC works by providing a small resistance when heated, which causes an increase in the current flowing through the circuit. This causes the contacts to heat up, providing a temperature activate switch. When the temperature reaches a certain threshold, the contacts open, and the circuit is disconnected.

In cases of short-circuit or overload, the PTC will experience an increase in current. This causes the temperature to rapidly increase, tripping the contacts and disconnecting the circuit. The device has the built-in capability to self-reset once the fault condition has been eliminated. When the current flowing through the device decreases, the PTC cools and the contacts close, allowing the circuit to resume normal operation. This makes the device an ideal choice for applications where circuit protection is vital but where space is limited.

The MF-R185-2-99 is designed to be used in a wide range of applications. It is often used in consumer electronic devices such as computers, cell phones, tablets, TVs, power supplies, and other sensitive electronic equipment. The device is also popular in industrial, automotive, medical, and aviation applications. The device is highly reliable, with an operating temperature range from 0 to +65°C and a rated voltage of 250V AC/DC.

In summary, the MF-R185-2-99 is a PTC resettable fuse which is designed to provide reliable circuit protection. The device features a thermal switch which trips in cases of short circuits or load overloads. Once these fault conditions are eliminated, the device is capable of self-resetting and restoring normal operation. The device is suitable for a wide range of applications and is often used in consumer electronic devices, industrial applications, automotive applications, medical applications, and aviation applications.
