We just get back from Chinese Lunar Spring Festival. We wish you a prosperous new year 2017, and may I say "Kung Hei Fat Choy" to you.

Dear, we jb capacitors company hereby sincerely address our highly appreciation for your kindness and cooperation for the years past. Constantly we'd like to offer you the stronggest support on high quality products with competitive prices. 
So dear, if you have any project that needs film capacitors or SMD/Radial/Large Can aluminum eletolytic capacitors, please fell free to send us your RFQ for my cross, let me help you cost down. Great thanks.

Electrolytic Capacitors

Electrolytic capacitors differ from other capacitors. One of the plates in an electrolytic capacitor is a liquid. 
The liquid is an electrolyte (an ion bearing liquid that conducts electricity, which is what gives the electrolytic capacitor its name. 
During the manufacturing process, a thin layer of oxide builds up between the electrolyte and the plate. 
This thin layer of oxide forms the insulating dielectric. Because the plates are large and the dielectric is thin, the capacity to store electricity is larger in electrolytic capacitors than in any other type. 
This makes electrolytic capacitors the capacitor of choice when building power supplies.

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have an aluminum plate and the dielectric is aluminum oxide. 
This type of electrolytic capacitor is inexpensive and is found in many power supplies. 
Their range in value from 1 farad down to less than a microfarad. E-caps can work voltages up to several hundred volts. 
Aluminum electrolytic capacitors can break down if they go through long periods of no power (the oxide breaks down.) 
Elco caps can be rejuvenated if connected to a power supply and a resistor--the long low current restores the oxide.
Elco caps are not suitable for working with high frequencies, and they're also used in radio frequency amplifiers or anywhere there are high currents and low frequencies.

In order to show a comprehensive product scope to our customers, jb updated Sample Box once again.

New Sample box part one is for Film Capacitors, which included with Motor Capacitors, Class X2 Film Capacitors, Premium & Superior Audio Capacitors, Metallized Polyester Film Capacitors and Metallized Polypropylene Film Capacitors

New Sample box part two is for Aluminum Electrolytic Capacitors, which included with SMD Aluminum Electrolytic Capacitors, Radial Aluminum Electrolytic Capacitors and Large Can Aluminum Electrolytic Capacitors (Snap-in Type, Screw Type, Lug Type)

If your business falls in one of the above two fields, you can ask our sales person to send the designated sample box to you.
We suggest to ship the sample box with your products to save the shipping charge at both of our side.

For one important notice, all the samples in the samples box are for display only and not for testing purpose.
If have interesting in testing our jb capacitors real samples. Please do not hesitate to contact our sales and send your samples request at our earlist.

jb capacitors company not only produce film capacitors, but also produce high quality aluminum electrolytic capacitors.

We mainly prdoduce SMD type, Radial(THT) type, Large can type (I.E. snap-in, screw, lug type).

We will not offer you the lowest prices, but we offer you the best quality;
We would like to explain to you for a period of time due to the prices, but don't like to say sorry to you due to the quality for a lifetime.

If simply for sake of  profit, absolutely can sell quickly by decrease the cost(quality), but we think, we will only pround of our  perfect quality and service !
