The most commonly used types of fuses in amateur radio equipment include glass-tube fuses, ceramic fuses, and blade fuses. Glass-tube fuses are compact and provide reliable protection against overcurrent conditions. Ceramic fuses are known for their high breaking capacity and are often used in high-power applications. Blade fuses, on the other hand, are popular in automotive radio equipment due to their compact size and easy installation. Regardless of the type, fuses play a vital role in safeguarding the equipment and should be selected based on the specific requirements and power ratings of the amateur radio setup.
Factors to consider when selecting fuses for amateur radio equipment
When selecting fuses for amateur radio equipment, there are several factors that need to be considered. First and foremost, the current rating of the fuse is crucial. It is important to choose a fuse with a current rating that matches or exceeds the maximum current that will be flowing through the circuit. Additionally, the voltage rating of the fuse should be taken into account. The fuse should have a voltage rating that is equal to or greater than the maximum voltage of the circuit. Another important factor to consider is the type of fuse. There are various types of fuses available, such as fast-acting, slow-blow, and time-delay fuses. The type of fuse chosen should be suitable for the specific application and provide the necessary protection. Finally, it is essential to consider the breaking capacity of the fuse. The breaking capacity refers to the maximum current that the fuse can safely interrupt without causing damage. It is important to select a fuse with a breaking capacity that exceeds the maximum fault current of the circuit to ensure proper protection.

Electronic Fuses to Protect Sensitive Circuits.
Thermal fuses have been used successfully for over 150 years as a basic circuit-protection device. They are effective, reliable, easy to use, and come in a range of values and variations to meet different design objectives. However, they have unavoidable shortcomings for designers looking for extremely fast current cutoff, the ability to self-reset, as well as the ability to function at relatively low current values. For these designers, electronic fuses—often written as eFuse or e-Fuse—are an excellent solution, sometimes replacing but usually supplementing the thermal fuse. eFuses are based on a simple concept of current sensing by measuring voltage across a known resistor, and then turning off the current flow via a field-effect transistor (FET) when it exceeds a design limit. The eFuse offers features, flexibility, and functions which a thermal fuse cannot provide.
