We have launched Gold Copper Tube and Film for a while. JGX series is not only our high class level among our Audio capacitors but also got competitive price.
Also, we got the fast lead time of 2~5 weeks.

It is Gold Copper Tube and Film Metallized Polypropylene Capacitors and the type is Axial type with precise capacitance tolerance of +/-5%. JGX is designed for audio instruments, especially for Audio amplifiers. Though,if there is higher requirement on tolerance, it is possible to offer.

Below is its specification, need more information, please send an email to us.

JFQP Density MKP DC Link-High Power Film Capacitors are metallized polypropylene film capacitors that feature good self-healing properties. These products provide high reliability, low ESR with high current capability, as well as a long useful life.

DC-Link capacitor for DC-filtering and energy buffering, targets power electronics devices for frequency converters, industrial and high-end power supplies, and solar inverters.

jb has wide product range can cross to different capacitors brand, our JFQD is  Double Sided Box Type Met Polypropylene Film Capacitor. It can be crossed to Vishay MKP383, Wima MKP 10. Kemet R76 series. Its capacitance value is from 0.001 to 0.068uF with high precision of capacitance. And, the rated voltage range is from 630VDC to 2000VDC. Moreover, the tolerance can reach +/-5% and +/-10%. Its application includes high voltage, high frequency and pulse circuit.

Features:
Double sided metallized polypropylene structure
Low loss and small inherent temperature rise
Excellent active and passive flame resistant abilities.
Negative temperature coefficient of capacitance

jb Capacitors Company post new announcement for JFV and JFW series metalized polypropylene film capacitor.

JFV series has changed the shell color to yellow, compliant with VDE and UL.
JFW series climate temperature category has upgraded from 105℃ to 110℃, comply with VDE and UL certification standards.

Are you looking for the Foil and Film Metallized Polypropylene Capacitors for your Audio application? Some of our customer claimed that come brand stop the production of it. But don’t worry, we are now launching it for customers.

We have two series, one called JLX, the other one is JMX. They are all Foil and Film MKP and are designed for Audio application; they have High Precise Capacitance of +/-3% and +/-5%. Please find the below is the summary of them.

Are you looking for below Polymer capacitors?
We produce PSS & PSR series, with low ESR, high ripple current, 2000hours at 105C”, offer very competitive prices and smaller dimensions.

Pls. check your RFQs and send your request to us, you will receive very satisfied offer.

PSS-2000H-at-105C-Standard-Radial-Polymer-Aluminum-Solid-Electrolytic-Capacitors
PSR-2000H-at-105C-Low-ESR-Radial-Polymer-Aluminum-Solid-Electrolytic-Capacitors

jb's PSR series conductive polymer aluminum solid electrolytic capacitor has the advantages such as wide operation temperature range, compact, low ESR（equivalent series resistance), excellent noise reduction and high resistance against ripple current. Using a capacitor with low ESR is preferable for industrial and commercial applications, both to improve power efficiency and to increase safety in cases of overload and overheating.

PSR - 2000H at 105°C Low ESR Radial Polymer Aluminum Solid Electrolytic Capacitors Specifications：
Operating Temperature：-55°C~ +105°C
Voltage Range：6.3V ~16V.DC
Capacitance Range：180 ~ 1500μF
Capacitance Tolerance：±20% at 120Hz, 20°C
Leakage Current(+20℃, max)：≤0.2CV (μA, after 2 minutes)

The PSR series is ideally suited for LED driver power supplies, adapters, laptop power supplies and medical equipment.
