Quote" Have you guys tried the jb JFX caps yet? Excellent and super cheap. Pretty sweet sounding. Several of the guys on the Audiogon thread use the copper cast Duelands and think these things are really good. They are not marked for outside foil so you will need to test and mark each one. Chinese caps for everyone!!!! So, we may have a new World's best cap coming."

Quote" Interestingly I also found out that Mundorf approached them to manufacture the JFX as OEM part for them so they could create a new premium brand to sell under the Mundorf branding. jb decided not to pursue this as it did not add value to their own brand which they want to promote with the JFX. The JFX caps display signs of a near perfect capacitor. +Total harmonic and IMD distortion and phase distortion are virtually immeasurable, while all losses are near zero in every aspect. jb JFX caps will allow your music to be accurate and uncolored in every way. Initial observations they seem well made no obvious flaws they arrived quickly, well packaged.

Quote" Whilst searching the web, I came across jb Capacitors, a Chinese manufacturer, I ordered a couple of their Premium capacitors and they arrive swiftly within a couple of weeks from China. 

After installing them I did notice an increase in clarity and treble response over the Blackgates that were previously installed. Overall very pleased with these capacitors and will not be going back to reinstalling the Blackgates."

Your feedback and advice will be highly valued. We will try our best to provide the best service and quality. We are sure jb Capacitors Company is your trusted choice.

jb Most Popular Three Types of Axial Lead Film Capacitors

Film capacitors adopt polymer films having a thin, aluminum metallization layer. This construction is very durable and stable, with excellent electrical characteristics. Axial and radial lead types are available.

About jb Axial lead film Capacitors, the series of JFG (JFGA, JFGB, JFGC, JFGD), JFXJSX are the most hot seller types among customers. Compared with their product performance, JSX is the best, JFX is better than JFG. They are all widely used in the field of audio equipment, exhibiting very low ESR and inductance and handle high audio current pulses extremely well. Other features are very low dielectric absorption and dissipation factors. Moreover, excellent Handling of High Current Audio Pulses with RoHS Compliant.

If you need Axial Lead Film Capacitors, welcome to try jb products JFG, JFX, JSX three series, we are sure one of them will suit your application. Any question or enquiry, please feel free to contact us!

jb Latest Test Report of JFX Premium Polyprolene Film Capacitors

We would like to share the latest test report of jb JFX Premium Polyprolene Film Capacitors to 
you. Welcome to try our capacitors and let us know your thinking.

Reporter: Mr. Lee. Riccio from United Kingdom, a member of the Pinkfish forum (Leeoh) 
Project: Upgrading a CD players Rotel RCD955AX.
Samples: jb JFX 4.7µF 250V +/-3% Bulk RoHS, 2 pieces
Datasheet:http://www.jbcapacitors.com/Plastic-Film-Capacitors/JFX-Premium-Metallized-Polypropylene-Film-Capacitors-Axial.html

Below is the Original letter from Mr. Lee. Riccio
Hello Iris, 
This is just a short letter to say thank you for the capacitors which arrived safely and my feedback having now installed the JFX Premium Polyprolene film capacitors in my Rotel RCD 955AX CD player as part of a series of upgrades to the player. 
Here they are installed in my CD player. They replaced two Blackgate F series electrolytic’s. 

Bigger than the Blackgate originals, but very easy to fit as legs were same diameter as Blackgate’s so they fitted through the pcb holes with absolutely no problems.



Aesthetically they look really nice and match very well with the remaining Op Amp decoupling Blackgates. 

Mods performed to my Rotel CD player:
Replace all power supply capacitors with Panasonic FC. 
Replaced all Transport, Filter, Decoder, DAC capacitors with Panasonic FC. 
Replaced all DAC Decoupling capacitors with Wima MKS series. 
Replaced Op Amps for HiFi audio grade from Texas Instruments. 
Isolated Filter chip and gave it its own independent regulated +5V power supply. 
Performed Filter Non Oversampling Modification. 
Replaced final audio output DC decoupling Blackgate F series capacitors for JFX Premium. 

How does it sound ?
I am very happy with the improvements bought with all the mods I made. So happy in fact I removed my Naim CD5i II CD player from my system which sounds considerably less good now and am keeping the Rotel in its place instead ! 
After then installing your JFX Premium capacitors the sound has opened up a little more and vocals seem to have slightly more but very clean treble. The noise floor is very low, which gives way to a very wide dynamic range probably why it seems the treble has increased slightly. 
Whilst is still early days, each time I play a CD the sound does seem to be improving with time, not huge differences, just more of the same clearer, wider, more dynamic. If the capacitor could be made a little warmer sounding would be ideal for CD replay. 
After nearly 2 weeks running of our JFX capacitors, I am pleased with the performance of the capacitors and have since we last communicated installed a very low jitter clock with its own dedicated power supply to replace the simple crystal clock in the CD player. 
This bought an immediate noticeable warmth and smoothness to the sound. So looks like your capacitors were always warm and rich sounding but the CD Player as standard wasn't allowing them to perform at their best !

Overall I am very happy with the quality of your product, service and delivery and have no hesitation in recommending to anyone seeking a sensibly priced, but high quality alternative to the usual well known, but in comparison can be very expensive American and European audiophile capacitor brands ! 

Kind Regards. 
Lee.

Some Feedback from jb Customer about JFX Capacitors and X2 Capacitors JFV

Hi Lilian, Our last amplifier was very well received and JB played a big role in this result. We tested several capacitors and chose to use the JFX in 2 parts of the amplifier (220nF and 330nF) and the X2 capacitorsin the grounding section. We are delighted with the quality of them all. 

I send you some photos of our lastest amp during a demonstration last August.

jb JFX and JSX Audio Capacitors are Non Polarised Type

Sometimes, customer will be confused by the so-called "outer foil" or the "inner foil"of our audio capacitors.
Today we would like to tell you more about this point. I am sure you will understand by below customers explanation.

" I have all my JFX caps soldered in at the moment, but plan to try some Jensen caps in place o them, so i will try to do the test as well. 
With a sensitive millivolt AC meter i think you could see the difference just by connecting it one way and touching the cap. 

The induced mains hum will be higher when the outermost foil is connected to the anode of the meter(maybe).

I think more and more that this is an example of "audiophile", which means that people searcing for better and better sound, and not always exactly knowing the technical aspects of it, they will assume one way is better because another cap manufacturer said so.

I feel that the JFX is a solid performer in either direction used(after all it is a bipolar cap as you stated), and i feel that the price/performance ratio is excellent."
