Our JFG film capacitors have 4 types, JFGA (round type MKT), JFGB (flat oval type MKT), JFGC (round type MKP), JFGD (flat oval type MKP).

They are our very strong series, we have unbeatable prices offer, short lead time support, and excellent quality guarantee.

For JFG series lead construction, there are various choice, such as Straight Axial Lead (longer & cut type), Kink lead, Copper terminal as lead etc.
We are very professional in Axial lead MKT, MKP film capacitors, with more than 34 years production experience, we are very proud to tell you "jb Capacitors is your best choice for capacitors".

Below picture for your example: JFGB Flat oval type, metallized polyester film capacitors, with Copper terminal as lead.

The primary purpose of a motor start capacitor is to briefly increase the motor starting torque as well as to allow a motor to be cycled on and off very quickly. It operates in the circuit by staying active long enough to allow the motor to be brought to 3/4 of it's full capacity. It is removed at that point by a switch in the circuit. You will find that the voltage rating is often one of these 110/125VAC, 125VAC, 220/275VAC, 250VAC, 330VAC.

jb produce AC motor starting capacitors for years, we have rich experience in film capacitors as well as Aluminum Electrolytic Capacitors.

We put JSW in our Aluminum Electrolytic Capacitors part, do you know why ? As motor starting capacitors use Aluminum foil as dielectric.

Below is our JSW series size table, if you need other capacitance or voltage, please feel free to contact with us, we can customize for you.

lMotor Starting Capacitor with cylinder shape and Aluminum case, normally the case will be covered by blue plastic material as the last process.

lCD60 Motor Starting Capacitor: Using aluminum foil as dielectric, which is the core, then fixed core asphalt filler.

lCD60 Motor Starting Capacitor: Helping A.C single-phase motor starting.

Electrical apparatue use metalized film with precisely quality control.

Low D.F. (dissipation factor), lower temperature rise.

High I.R. (insulation resistance) and small size.

Good capacitance stability, Excellent self-healigh property.

The specific type of capacitors with high electrical characteristics are widely used in single phase A.C. motors with rated voltage of 110V-330V and the frequency of 50Hz-60Hz to get high rotary torque at low starting current, and also the motor at a lower starting current under high torque.

jb Capacitors developed more production lines for motor capacitors since last year, now we have 28 types of JFS motor running capacitors, and JSW motor starting capacitors.

CBB60: Motor Running Capacitor (JFS-10~21)
CBB61: Motor Running Capacitor JFS-A~D, JFS-5~7, JFS-9)
CBB65: Motor Running Capacitor (JFS-22~24), and JFS-20, JFS-21 are fully encapsulated by retardant epoxy resin. No need the case cover anymore. By doing this, the products will have high reliable and smaller size.
CD60: Motor Starting Capacitor (JSW)

Well, what is the difference between motor running and motor starting capacitors? here below we summarize for you.

1. Different Performance: running mean keep working, while starting purpose just let the machine to start, and the working time only last for few seconds actually.
2. Different Stuffing: CBB60, CBB61 are filled with epoxy resin, CBB65 are filled with refined castor oil and wax, and CD60 are filled with asphalt.
3. Different Dielectric: The dielectric of starting capacitors is Aluminum foil, while in running capacitors, it is metallized polypropylene film.
4. Different Capacitance: Running capacitors is started from 1uF (1uF~150uF), while Starting capacitors is started from 50uF (50uF~1500uF).

Also different outer case (Plastic case, and Aluminum case), application, inner construction...

jb Capacitors produce good quality Axial MKT & MKP Film capacitors, 4 types,  JFGA~JFGD, axial leaded, cycloidal, flat shape. 
Widely used in instruments and the DC& AC circuit of the household equipment and the fractional frequency circuit of acoustics systems.

Firstly, we want to make a test with you . Do you know what is 2+2 terminals, 2+4 terminals, 4+4 terminals?
Well, from the name of terminal we know they are refering to CBB65 Motor Running Capacitors.

2 means 2 pins terminal, 4 means 4 pins terminal. Very interesting, right?
JFS - 22 : 2+2 terminals type, JFS - 23: 2+4 terminals type, JFS - 24: 4+4 terminals type

At the same time, we also can make different terminals at customer request. All we want to do is to provide most comprehensive products to jb customers.

Please refer to below picture, if you need more information, please feel free to contact with us.

In China, most factory produce CBB60 motor running capacitors with plastic case and with a cover. Why so ? 
Firstly is cost down, secondly is most factories are selling the products to domestic market, most people should know domestic market do not need high requirement compared with overseas market.

However, we jb Capacitors Company main maket is Euopen countries. We must export superior quality to our customers. So we make CBB60 different with most China factories.

Our JFS - 20 and JFS -21 are fully encapsulated by retardant epoxy resin. No need the case cover anymore. By doing this, the products will have high reliable and smaller size.
