jb Tells You How To Pick Audio Capacitors

So, you’ve decided to repair/upgrade your vintage audio equipment by replacing the capacitors. When you go to Mouser or Digikey, however, you are presented with tens of thousands of choices. Even after drilling down to the specified capacitance and voltage, you have dozens of candidates, differentiated by such esoteric terms as Tan Delta, Q Value, ESR, etc, etc, etc. Here I recommend to you a type of product designed for ultimate musical performance, that is jb Premium Metallized Polypropylene Film Capacitors - JFX.

jb Capacitors JFX series high end audio capacitors are widely used in high end audio equipments, cross overs, amplifiers, loudspeakers etc. The following is the evaluation of our customers.

Your JFX line is a very good speaker crossover cap and at its attractive pricing should be replacing most caps in all the hi-end speakers. All competing caps which aren't as good as the JFX. 
----Paul Weitzel

Our advantages: Competitive Prices , Short delivery, high quality, lower MOQ, good customer service, free samples etc..

jb JFX Series Caps are Designed for Ultimate Musical Performance

jb JFX caps are a premium audiophile grade capacitor designed for quick transient response and ultimate musical performance. Every attention to detail was put into the JFX capacitor line to insure premium performance.

A premium grade of “defect free” aluminum metallized polypropylene film was chosen from an industry leading film supplier. All leads are lead free (RoHS Compliant), oxygen free 99.99% pure copper. Each lead is attached to the body of the capacitor with ultrasonic welding. To further reduce equivalent series resistance and improve long term reliability, the leads are then soldered with lead free silver solder. JFX caps are then wrapped in flame proof polyester tape and the ends are epoxy filled. Before final packing, each JFX cap is tested with certified premium quality Wayne Kerr capacitance bridges to insure the ±3% ~ ±5% tolerance nominal value.

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.
