Panasonic New Product Brief: ETQ PAMR33JFW Power Inductor

Me today: *must overcompensate by purchasing every version that ever becomes available from every known seller*

Electricity is getting more and more advanced every day, but certain things can never change. A few devices are the reason electricity works and operate smoothly without any danger. Many things make up an electrical system.

A fuse is an electrical device used to protect circuits from overcurrent or overload and even protect the circuits. Fuses come in a lot of different designs and colors, but their functioning is the same. Here are electrical fuses and their types:

1.Cartridge Fuses

Cartridge fuses are used to protect electrical appliances such as air conditioners, motors, refrigerator pumps, etc. this is best where high voltage rating and currents are required. They are available up to 600A and 600V AC which are even nicer. 

They are used in industries and commercial areas also as home distribution panels since they are efficient and work best for bigger sizes. Fuses help make it smoothly work without causing any danger. 

2.D-Type Cartridge Fuse

D-type fuses contain an adapter ring, cap, base, and cartridge. Here the fuse base is connected to the fuse cap, where the cartridge is kept inside the fuse cap. The circuit is completed when the tip of the cartridge makes contact with the help of the fuse link conductor.  

These fuses are efficient and help with the smooth functioning of the whole system since they are so safe and strong. 

3.High Voltage Fuse

HV fuses are used in power systems to protect the power transformer, instrument transformer, and distribution transformer where circuit breakers might not save the whole electrical circuit.

High voltage fuses are rated for more than 1500V and go upto 13V. The element of this fuse is made out of copper, silver, or tin. The chamber should be filled with boric acid in case of expulsion type. 

4.Bolted Type Fuses

These fuses, also known as plug-in fuses, come in a plastic body and two metal caps to fit in the socket. They are mainly used in automobiles for wiring and short circuit protection purposes. 

Glass tubes are widely used in the automotive industry. The ratings of these are as low as 12V to 42V. In these types of fuses, the fuse base is directly connected and helpful in many ways.

5.Surface Mount Fuse

SMD fuses, also known as electronic fuses, are mainly used in DC power applications, like hard drives, cameras, DVD players, etc. They are put where space playing is an important part because SMD fuses are tiny and hard to replace.

These fuses are very helpful and make the whole system function without risk of any failures or short circuits. 

The packages are classified into two kinds on the basis of how they are mounted on a circuit board.

Through-Hole Mount Packages

They are designed in a way that the lead pins are stuck through one side of the board and soldered on the other. They are bigger in size as compared to the other kind. These are majorly used in electronic equipment to compensate for the board space and cost limitations.

Surface Mount Packaging

Surface mount packaging follows the technology of mounting or placing the components directly on the printed circuit board surface.  Although this process of fabrication helps do things quickly, it also increases the chances of defects. This is because of the miniaturization of components and also because they are mounted extremely close to each other.
