jb Customer's comment for jb film capacitors.

jb film capacitors use laser printing for marking, and due to advanced technology in epoxy coating, our capacitors' appearance looks much better than most of other vendor in China.
 
Many customers and lab's tested our quality, we received more and more feedback regarding our high quality film capacitors. 
 
Please check our website: http://www.jbcapacitors.com/ 
Please send your JFB metallized polyester capacitors and JFV X2 MKP capacitors inquiry to jb capacitors. Thank you.
 
From: Sergei
 
Dear May, 
 
We did tests as well with jb Capacitors from our foreigner colleagues, and we found that quality is very good, and one more thing--they Looks Nice which is also important!
So we decided to send you our order to see your proposition for full list, including items we asked you earlier, we will do this order at this time. 
 
 
Best Regards,

Introduction of Mr. SAM BENELBAZ

French, retired, have the hobby of TUBE do it yourself; used to work in IBM as a professional 
of electronics; after that for LASER a company involved in point of sales solutions and hardware maintenance, in that position, he bought a French company sic-safco. 

Mr. SAM BENELBAZ is member of some forums in US and France, some are AUDIOASYLUM.com and DIYAUDIO.com fun withtubes. com and some others.

Original letter from Mr. SAM BENELBAZ

Dear iris,
i hope you are ok. 
I have installed the JFX capacitors last Sunday and i can now give you my impressions.

But first i have to tell you what speakers and amps i used for the test:

The speakers are YAMAHA NS1000M well known in the market and very revealing .
The amps are two american CARY tube amps model 40M using 6SL7 and EL34 tubes.
In this test the EL34 are NOS Philips EL34 of the XF2 series (the best).

The Yamaha crossover was using mainly NICHICON capacitors using metalised paper .
I did replace every capacitor with the ones you send me.
The CDs i use for the test are very good Cds , classic music and jazz mainly.
I know them very well and can hear the differences well. 

Now lets come to the findings:
The JFX have good audio imaging and you can hear obviously more details than with the nichicon .
I think this is because they are wounded very tight.
Congratulations to the worker who did the job.

At this very moment i think that JFX are very good capacitors for cross overs and with their price-sound ratio you can go to the market without any shame.

My best regards
sam

jb RC Unit X2 Film Capacitors, Parallel Connection

We jb Capacitors can offer both insulated lead, and jb standard CP wire lead for RC unit X2 film capacitors.

jb Capacitors is ISO 9001:2008 certificated professional manufacturer for full range of Film Capacitors and standard SMD electrolytic capacitors.




jb Has Great Support for CBB61 Motor Capacitors -- JFS-6

Motor capacitors are operation capacitors for single-phase induction motors with auxiliary winding and three-phase motor in steinmetz circuits.

Motor capacitors are self-healing capacitors, i.e. a weak point in the dielectric would become ineffective by itself since the metal coating evaporates at the weak point.

We jb produce 18 types of Motor Start Film Capacitors, with high quaity, we also offer competitive prices and short lead time, we welcome your inquiries to info@jbcapacitors.com

Below are some main applications for motor start capacitors. and our JFS-6 series motor start capacitor picture.
Household and domestic appliances.
Office machines.
Heating and ventilation techniques.
Garden and recreational equipment.

jb Capacitors Dual Run Capacitors

A dual run capacitor supports 2 electric motors, such as in large air conditioner or heat pump units, with both a fan motor and a compressor motor. The dual capacitor has 3 terminals labeled "C", "FAN", and "HERM" for the common, fan, and hermetic compressor connections.

Round dual run capacitors (shaped as round cylinders) are commonly used for air conditioning, to help in the starting of the compressor and the condenser fan motor. Dual capacitors come in a variety of sizes, depending on the capacitance (µF), such as 40 plus 5 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, but not a 370 in place of a 440 volt. The capacitance must stay the same within 5% of its original value. An oval dual run capacitor could be used instead of a round capacitor, but the mounting strap should be changed to better fit the oval shape.

IEC/EN 60252-1 2001 specifies levels of protection for motor run capacitors
• P0 - no protection
• P1 - fail open circuit or short circuit
• P2 - fail open circuit only 

jb Capacitors Motor Start Capacitor

Start capacitors above 20 microfarads (µF) are always non-polarized Aluminum Electrolyic Capacitors with non solid electrolyte and therefore they are only applicable for the short motor starting time.

Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly. Start capacitors have ratings above 70 microfarads (µF), with four major voltage classifications: 125 V, 165V, 250 V, and 330 V. A start capacitor stays in the circuit long enough to rapidly bring the motor to 3/4 of full speed and is then taken out of the circuit, such as by a centrifugal switch that releases at that speed. The motor after that runs more efficiently with a run capacitor.

jb Capacitors Run Capacitors

Run capacitors are mostly polypropylene film capacitors and are designed for continuous duty, and they are energized the entire time the motor is running. Run capacitors are rated in a range of 1.5–100 microfarads (µF or mfd), with voltage classifications of 370 V or 440V.

Single phase electric motors need a capacitor to energize a second-phase winding. If the wrong run capacitor is installed, the motor will not have an even magnetic field, and this will cause the rotor to hesitate at those spots that are uneven. This hesitation can cause the motor to become noisy, increase energy consumption, cause performance to drop, and cause the motor to overheat.
