Fuses provide an important form of overcurrent protection in electrical systems.

The BK/MDA-20NX is a specially designed fuse that offers reliable overcurrent protection for electronic circuits. It is designed to prevent the risk of short circuits, overvoltage and other faults. It features a slim design with an internal ‘S’ shape construction which helps to reduce the contact impedance between the fuse conductors and the fuse body. The fuse also has a very low contact resistance, making it ideal for protection of sensitive electronic circuits.

The BK/MDA-20NX is a low voltage surface mount fuse. Its small size allows it to be used in a wide range of applications such as consumer electronics, automotive, industrial and medical devices. Its contact resistance is very low, which makes it an ideal choice for applications which require protection from high currents. The fuse is also rated for fast-acting current interruption, meaning it can quickly detect and disconnect the supply current when a fault occurs.

The BK/MDA-20NX is designed to operate within a certain range of operating voltages. Depending on the application, the recommended operating voltage range can vary from 1.5V to 20V. As a safety measure, the fuse will break the circuit when the voltage exceed the maximum rated voltage. This helps to ensure that the circuit is not damaged by accidental overvoltage.

The working principle of the fuse is based on the property of a wax pellet which is embedded inside the contact tip. The fuse functions as a switch that will open once the current exceeds the rated current values. The embedded wax pellet melts when the overcurrents exceed the rated current of the fuse, and this interruption leads to the opening of the contacts and the disabling of the circuit. This ensures that circuit parts are not damaged, and the fault is prevented from propagating further down the line.

The BK/MDA-20NX offers reliable overcurrent protection for a wide range of applications, including consumer electronics, automotive, industrial and medical electronics. Its slim design and low contact resistance make it ideal for use in these applications. Its fast-acting current interruption ensures that the circuit is disconnected quickly if a fault occurs, and its operating range offers the necessary protection against overvoltages.
