With various kinds of original materials prices keep increasing today, we jb capacitors take a surprised news to our customers! 
Yes, you are not seeing wrong, our price of SMD aluminum electrolytic capacitors much decreased, very low!

We have strong and hot item such as JCS- SMD aluminum electrolytic capacitors 2000 hrs at 85°C and JCK- SMD aluminum electrolytic capacitors 1000 hrs at 105°C etc.
Happy? Excited? Thrilling? Please just calm down and send inquiry list to us for detailed quotation to see.

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), JFX, JSX 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!

We will exhibit at Munich again this year.
Now we are preparing samples, leaflets and some gifts for the exhibition.

If you are interested in our samples, promotion materials or small gifts, please contact us and check a meeting time with our sales, you can get the materials free at our Booth. 

Looking forward to see you at Munich fair in November. Our booth No. B6.560/14.

jb is specialized in production of different type capacitors, offering our customers the best quality products with fast delivery and the best after sales services.

As you know, normally, JSX Superior Metallized Polypropylene Film Capacitors biggest capacitance value is 100uF. Good news to enjoy with all of our jb customers that we are capable of manufacturing capacitance value up to 150uF Audio Capacitors. And not only that, owing to our good production capacity, we can product even larger capacitance to 300uF, it just be based on your specific requirements. We hope jb professional manufacturing ability will leave deep impression to you.

jb Capacitors will exhibit the Munich Electronica Fair on November 8~11th, 2016, booth No. is  
B6.560/14.

Welcome all of our old customers or new customers come to visit us, take back the samples you want, discuss with our sales for the cooperation,or ask for other questions you hope to know about us.

We aim to be a international brand in the capacitors industry, in jb Capacitors, you will find Profession, Efficiency, Trust and Sincerity.

We are glad to share a piece of good news with jb faithful customers. jb JFV - X2 Metallized 
Polypropylene Film Capacitor has adopted Laser Marking printing instead of Ink printing.

With great flexibility of the process, Laser marking makes high quality, fast making speed. What’s more, it is RoHS compliant. The appearance of capacitor becomes better and we confirmed it will not impact any functions.

The specifications of jb JFV - X2 Metallized Polypropylene Film Capacitor:

A motor run capacitor is used to continuously adjust current or phase shift to a motor’s windings in an effort to optimise the motors torque and efficiency performance. 
All run capacitors are designed for continuous duty, and as a result, have a much lower failure rate than start capacitors.

Main Feature:
Motor run capacitors utilize low-loss Metallized polypropylene Zinc aluminum film for dielectric. 
The motor run capacitors are encapsulated with resin and housed in a self-extinguishing plastic case which allows for superior reliability and a high mechanical shock and vibration strength. 

The motor run capacitors is ideal for start and run applications in single-phase asynchronous motors and general A.C. applications at industrial frequencies. 

The motor run capacitor is small in bulk, has long life-span and good self-healing characteristic. 

The motor run capacitor is widely used as the start up and running capacitor that is special for micro water pump, cleaning machine, washing machine, and single-phase water pump motor.

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.
