What is Capacitance ?

The capacitance of certain capacitors decreases as the component ages. In ceramic capacitors, this is caused by degradation of the dielectric. The type of dielectric and the ambient operating and storage temperatures are the most significant aging factors, while the operating voltage has a smaller effect.

The aging process may be reversed by heating the component above the Curie point. Aging is fastest near the beginning of life of the component, and the device stabilizes over time,electrolytic capacitors age as the electrolyte evaporates. In contrast with ceramic capacitors, this occurs towards the end of life of the component.

Our jb capacitors has various capacitance.Such as our JFA-Mylar Polyester Film Capacitors, capacitance range from 0.001 to 0.47μF.

jb capacitors is our favorite suppliers

My name is Peter Sivak. I am electrotechnical engineer. I work as head production. Our company has many suppliers of many components include electrotechnical materials.

As you know, the production us very sensitive for quality ,delivery time and dependent of flexibility suppliers and last but not least the price. The jb capacitors is our favorite suppliers,

because they fulfill the previous condition.

The jb capacitors company really want keep a promise, or the request of customers. Their dealers are very kind , helpful and friendly. It is good advance how to be successful.

It will be very good if every of our suppliers will be as good as jb.

Mylar Polyester Film Capacitors --JFA (CL11)

jb capacitors produce film capacitors since 1980. Have a very good reputation in use with consumer&industrial electronics.

Our JFA Mylar polyester film capacitors (CL11) are widely used for energy saving lamps (CFL), ballasts.. many lighting products.

JFA series Mylar polyester film capacitors, CL11 series, many customers also called green capacitors, with very small size, low price.

jb capacitors company offer very short lead time for mylar film capacitors.

customer comments for X2 Met polypropylene film capacitors

From: Tony Szullo

To: JB

Attn.: Sophia

Dear Sophia,

Here is our statement about the X2 capacitors:

We are testing all incoming batch of X2 polypropylene capacitors for breakdown voltage. According to our internal quality standard, this must be minimum 2000Vdc. The shipment which we received from JB Capacitors is consistently well above this threshold on all purchased values from 0.022uF to 1uF. According to our QA reports, we have not experienced a single failure in the past 12 months period.

Best Regards,

Tony Szullo
