PTC Resettable Fuses is a type of electric current protection device which is widely used in fields like power electronic, lighting, motor and instrument. The presence of these devices is used to protect the users and the equipment from hazards of electric shock and fire. MINIASMDC150F/24-2, which is one of the most popular PTC Resettable Fuses, is commonly used in applications such as AC/DC adaptors, switching mode power supplies, electronics transformers, CB radio, Rechargeable battery chargers and UPS (Uninterruptible Power Supplies).

The MINIASMDC150F/24-2 operates in accordance to the principle of self-recovery. It was designed with a ceramic disc containing a conductive adhesive and a metal plate. The conductive adhesive is connected to a resistor which, when electrified, produces a certain amount of heat which melts the solder on the metal plate, thus preventing the current flow. When the current surge is cut off, the fuse automatically resets and the solder cools down gradually, thus reconnecting the circuit.

When the current running through the MINIASMDC150F/24-2 exceeds the preset value, the temperature of the ceramic disc will start to increase gradually. This increased temperature will cause the metal plate and the solder to disconnect, thus cutting off the current flow. As the heat dissipates, the ceramic disc temperature will decrease and the conducting adhesive will reestablish the contact between the metal plate and the solder, thus resuming the current flow.

The MINIASMDC150F/24-2 offers a large range of features. Its maximum rated current is 2.4A and its maximum voltage at the rated current is 30Vdc. The rupture capacity is 75A/125Vac, which is much higher than the standard IC fuses. Its high cycling capability, superior aging characteristics and high electrical characteristics ensure that it can work under a wide range of temperatures. Its small form factor also makes it well suited for tight spaces.

The MINIASMDC150F/24-2 is a reliable solution for the protection of high-end electrical equipment and devices from overcurrent, short circuit and other abnormal conditions. Its advantages include long service life, high accuracy, wide temperature range, and low power consumption. Thanks to its self-resetting properties, it is becoming increasingly popular as a way to protect sensitive electronic systems from harm.
