jb Occupy Market Share of Fine-Tuning Capacitors(Ceramic Trimmer capacitor)

Ceramic Trimmer capacitor is a semi-fixed adjustable capacitor, and its electrostatic capacity can be changed freely.

The working principle of JKA trimmer capacitor: Change the overlapping area of electrodes. One of the electrodes is fixed to sandwich the dielectric, and the other is made as a variable electrode. The change in the overlapping area of the two electrodes (the area of the opposite electrode) can change the electrostatic capacitance.

jb Capacitors Company’JKA series: surface mount ceramic trimmer capacitors with mini size, five kinds of capacitance values, different color is easily identified.

jb Capacitors Company To know the Class-X Capacitors, and the Reason of Their Safety

When it comes to safety, normally, there are two types, one called Class-X, the other called Class-Y. Today we are going to talk about Class-X. This is jb capacitors company’s strongest series. We have unbeatable advantage on price and lead time. Most importantly, our quality is stable and reliable with assurance. Our X2 capacitors has certified with VDE, ENEC and UL.

They are generally designed and used in AC line filtering in many electronic device applications. X2 capacitors is also called EMI/RFI suppression capacitors and AC line filter safety capacitors. The generation of EMI/RFI and the negative effects associated with received EMI/RFI can be minimized by Class-X capacitors. They are directly connected to the AC power input, that is, the AC “line” and the AC “neutral”, to achieve the task. So, why X2 capacitors is safe? The reason is that the direct connection to the AC voltage, the capacitors may be subjected to overvoltage. Therefore, this kind of failure will cause a protection, and will not cause any electrical shock hazards.

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.
