Fuses Unlimited

Electronic fuses are current sensitive devices designed to serve as an intentional weak link in an electrical circuit. They are typically rated at 300 volts or below and are designed to protect circuits in the limited space requirements of electronic equipment such as consumer electronics, computers, instrumentation, power supplies and telecommunication equipment. Electronic fuses are classified as either subminiature or miniature type fuses. The subminiature fuse, category includes the Pico, , , Micro, , 2.3 x 8mm, cartridge, , 3.6x10mm cartridge and the surface mount fuses. Surface mount fuses come in industry standard 0402, 0603, 1206 package sizes as well as some larger non-standard sizes. Miniature electronic fuses refer to the typical cartridge-style fuse types such as the 1AG, through 8AG, size, 5x20mm, 5x15mm and midget size fuses

Semiconductor fuses are very fast acting, current limiting, fuses that offer low melting integral (I2t) values and peak let-through currents. Voltage, ratings range from 130 to 1, 500 volts. These fuses are designed to protect power supplies, rectifiers, diodes, thyristors, triacs, transistors and other solid-state power semiconductor devices. They are offerred in ferrule, bolt-in, blade and hockey puck casing styles.
