Capacitors
Capacitors are used to store electrical charges and can supress electrical noise and voltage spikes, smoothing any severe voltage fluctuations in the system.
They are constructed by two conducting, typically aluminum, plates separated by a dielectric such as plastic, paper, mica film, ceramic and even vacuum.
Their ability to charge and store charge allows timed circuits to delay electronic devices from turning on or off. This charging capacity can keep a circuit operating for a certain period of time after it has been shut down. Other than energy storage they can be used for power conditioning and correction, supression and coupling, sensing, oscilalting and more. Nowadays it is very hard to find any electrical product without one type of capacitor or another.

Epoxy Coating Powders for capacitors
DK18-05: An Industry Standard for Passive Electronic Components
Used for years for passive electronics, DK18-05 continues to fill a need with customers who are not yet ready to make the move to “environmentally green” products. Due to its wide processing window, DK18-05 can be manually dipped or automatically dipped into a fluidized bed. Though it is recommended for passive electronics, due to its versatile nature, DK18-05 is also used for (magnetic) cores, and other components. DK18-05 is available in blue, gold, green and black colors.
DK40 GR: Halogen-Free for Passive Electronic Components
DK40 GR is available in both Blue and Gold and is the next-generation epoxy coating powder for passive electronic components. Formulated as an “environmentally green” product, it is a halogen-free material, which means it has been formulated without bromine, antimony, or phosphorous additives. Launched in 2012 into the European market, it is being evaluated by all major passive electronic manufacturers.
