Why Does a Capacitor Smell Like Fish?

The fishy smell in capacitors comes from the electrolytic chemicals that are used to make them. This smell can be unpleasant, but it does not mean that the capacitor has burned out or gone bad.

Some people believe that the smell of fish is a result of the capacitor burning up. This is not true, though. It is just an old wives’ tale.

What is a capacitor and what are its uses?

A capacitor is an electrical component that can store a charge. It is used in many types of electronics like radios, televisions, and computers.

To understand how a capacitor works, we need to know what an electric field is. An electric field is a force exerted by the electric charges on each other. A capacitor stores energy in the form of an electric field between two plates with opposite charges on them.

What causes capacitors to smell like fish?

A capacitor is an electronic component that stores energy. It can be in the form of a solid dielectric or a gas, and it can also be in the form of an electrolytic cell with a liquid electrolyte.

The capacitors are used to store electric energy and to maintain electric potentials. The capacitors are usually made up of two metal plates that are separated by an insulator, and when the dielectric is charged, it stores electric charges in the space between the plates.

Capacitors are used in many electronics such as computers and televisions because they have a quick response time, they can store more charge than batteries, and they don’t wear out as quickly as batteries do.

Why do electronics sometimes have a fishy smell?

The most likely explanation is that the smell comes from the solder paste used to attach components to circuit boards. The solder paste contains a mixture of lead and tin, which emits a fishy odor when heated.

The smell is not harmful but it can be very annoying for some people.

Electronic devices are often associated with being new and clean, so the idea of them having an odor is unsettling for many people. But this smell is harmless and doesn’t pose any health risks.

How do you remove the fishy smells from your electronic devices?

Whether it’s a laptop, smartphone, or tablet, electronic devices are prone to getting a fishy smell. One of the reasons for this is the accumulation of dirt and dust particles on the device. To clean your device and remove that fishy smell from your electronic devices, you need to use a vacuum cleaner or compressed air to remove all the dust and dirt from your device’s vents. You should also use a cotton swab dipped in rubbing alcohol to clean out any vents that you can’t reach with compressed air or a vacuum cleaner.


Electronic devices might seem like they are indestructible, but they do have one weakness. They start to smell like fish over time. This is because the capacitors inside the device are leaking and emitting a fishy odor.

The solution to preventing your electronic devices from smelling like fish is to replace the capacitors with ones that don’t emit a fishy odor. You can either buy new capacitors or find some on eBay or Amazon for much cheaper prices.


What do capacitors smell like?

Capacitors are typically made of two metal plates that are separated by an insulating material. The plates are connected to the other components of the circuit by wires. When electricity is applied to the plates, a charge builds up on the surface of each plate. The charge on one plate repels electrons from the other plate, which builds up a negative charge on that side.

The smell of capacitors is caused by ozone gas, which is released as a result of electric discharge and may be detected as soon as 5 minutes after the capacitor has been discharged.

What does a blown capacitor smell like?

A blown capacitor will have a very distinctive smell to it. It is usually described as “acrid” and “sour.”

The smell of a blown capacitor is not the only thing that will be noticeable. There will also be an acrid, sour taste in the air. The metal can also get very hot to the touch and may even start to melt or burn.

Do capacitors smell when they fail?

The smell of a capacitor is caused by the burning of insulation material. The smell is usually a sign that the capacitor has failed.

Is a blown capacitor toxic?

A blown capacitor is not toxic by itself. However, if it has been leaking electrolytes, then it can be. This is because the electrolyte is a corrosive substance that can cause burns and other injuries when ingested.
