jb JFX Audio Film Capacitors--Best Capacitor on Sound Application

Dear Purchasing Manager,

Hello! This is Ms. Lilian from jb capacitors company, so nice to write to you. We are professional 
manufacturer for MKT MKP film capacitors since 1980. visit our website: www.jbcapacitors.com  

Today, I bring you our most strong series Film capacitors----JFX series Axial type premium metallized polypropylene film capacitor, pls. check below our datasheet and photo. 
This JFX series Axial type MKP film capacitor, widely used in Passive Crossovers, Loud speakers, amplifiers etc...high end audio equipments. 


Compare with Mundorf, Auri cap, Mallory, Jantzen, Erse audio, our lead time is much better, and  more important, our price is very good. 

Here we have 4.7uF 250VDC +/-5% stock samples, welcome to check prices and ask for samples.

Добрый день!

Это мисс София из компании JB capacitors.

Могу ли я пригласить Вас посетить наш стенд на 2012 год EXPO Electronica в Москве 11 апреля ~ 13?

Компания JB capacitors занимается производством пленочных и электролитических конденсаторов с 1980 года. Если Вы нуждаетесь в высококачественных конденсаторах для производства или торгуете пассивными компонентами, наша компания может предложить хорошие цены, отличное качество продукции, а также быстрое изготовление заказа.

Могли бы Вы рассмотреть JB capacitors как своего нового поставщика?

Ниже перечислены основные, самые популярные виды производимых нами конденсаторов:

JFA – Полистирольные пленочные конденсаторы (CL-11)
JFB -- Металлизированные пленочные конденсаторы ( CL-21, K73-17)
JFL-- Металлизированные полипропиленовые конденсаторы CBB-21
JFV--< Class X2 > Помехоподавляющие полипропиленовые конденсаторы 275VAC
JFP-- Высоковольтные полипропиленовые конденсаторы (CBB81)

jb Promote JFV X2 MKP Film Capacitors

Keywords: X2 film capacitors, MKP capacitors, Interference suppression film capacitors.
 JFV X2 film capacitors are produced by jb capacitors company, a ISO 9001:2000 certificated factory.
 JFV X2 film capacitors advantages:
 1. JFV X2 is safety capacitors, with safety approvals, UL, TUV, CE approvals. datasheet:
http://www.jbcapacitors.com/pdf/JFV-X2-Metallized-Polypropylene-Film-Capacitor.pdf
2. Our JFV X2 is with good quality under " jb capacitors " brand.
3. Many customers use our JFV X2 instead of Epcos B81 130, Vishay MKP3382, EVOX RIFA PHE840M, Panasonic ECQU, Arcotronics R46...
4. JFV X2 capacitors have very short lead time, around 3-6 weeks. Some popular items like 104K and 224K, stock availble.
5. Good sales support, reply to customers within 30 mintues after receive your emails.
6. Good experience in power supply, lighting, white goods.
7. Good samples support. 
 
Thank you for helping promote our JFV X2 film capacitors to your customers, especially those power supply, lighitng and white goods projects.

jb Tell You How to Test A Capacitor with An Ohmeter

You can use your multimeter as an ohmmeter to test the capacitor.

1) Discharge the capacitor by shortening its leads. that is - use a wire and connect the leads of the capacitor together. this will discharge it.
2) Put your multimeter in the high ranges 10k-1m
3) Connect multimeter to capacitor leads(observe the polarity if electrolytic). at soon as the leads make contact, the meter will swing near zero. it will then move slowly toward infinity. finally the meter would come to be infinite ohms because the capacitor is being charged by the battery of the multimeter.
4) If the capacitor is bad, it will go to zero ohms and remain there. this is called a shortened capacitor
5) In the case of an open capacitor there will be no ohmmeter indication.
6) Some capacitors have a low dielectric leakage. you will know this if the ohmmeter comes to rest at a point lower than infinite. test a known good capacitor of the same type to be sure.

This test works for large capacitors. Tiny capacitors can only be checked with a capacitance meter, or by using them in an AC circuit and checking for variation from calculated voltage drop.
Pls. focus on jb most strong series:  JFB--MKT (Metallized Polyester ) Film Capacitors &JFV--X2 MKP (Metallized Polypropylene) Film Capacitors.
