Protect your electronics with miniature fuses

Fine-wire fuses are protective devices in electrical circuits designed to prevent damage from overcurrent. The cylindrically shaped fuses contain an element that melts and breaks the circuit when the current exceeds a certain value. Micro fuses are used in numerous electronic devices and systems such as computers, televisions, radios, home appliances and vehicles. They are critical to safety as they help prevent fires and damage to equipment due to electrical malfunctions.
