Some customers of us require the Metallized polypropylene film capacitors with 4 pins, and we do offer it as JFQP series. Of course, with best price, short lead time and the most competitive price as usual. Jb is specialized in production of all kinds of capacitors, with 40 years production experience. If you are interested in it, please feel free to send us RFQs: info@jbcapacitors.com

4 Pins JFQP FEATURES:
High ripple current, high dv/dt withstand capability.
Low ESL and ESR
Plastic case, epoxy resin sealing（UL 94V-0)
DC-Link and coupling/filtering for Inverter, Industrial and high-endpower supplies and Solar inverter

Recently the market lack of SMD Ceramic Trimmer Capacitor very much, and the delivery time is very long. 
We keep some stock for this series, and make sure high quality. Are you looking for this item? Please contact us asap.

JKA - SMD Ceramic Trimmer Capacitor 
Features:
• Ultra miniature size with external dimensions of 3.2(W) x 4.5(L) x 1.5(T)mm
• Color coded case permits easy identification
• Very good Q and high resonant frequency
• Designed for reflow soldering
• Lowest capacitance drift
• Sealed construction prevents the penetration of Flux and Dust

Screw type become one of our strong series recently. The lead time can achieve 3~5 weeks. With all the delay of current raw material situation, this is very fast lead time. We offer Fresh and Original products, not stock. jb is dedicated to offer the best service to our customers.

For JML series, it has wide range of temperature of -40°C~+105°C and -25°C~+105°C respectively. For low voltage of 10V~100V, the temperature is -40°C~+105°C, on the other hand, 160V~400V has the range of -25°C~+105°C. That is only standard specification. jb has the customized service.

The application of JML is used for computers, communication powers Hi-ripple circuit of electric vehicle, electric train, general-purpose inverter.

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 Capacitors Company launched new series this year—JFQP series - Metallized Polypropylene Film Capacitors DC Link-High Power. It is ideal for Inverter, Industrial and high-end power supplies, frequency converters and Battery chargers.

It includes below features: Plastic case, epoxy resin sealing. Low ESL and ESR. High ripple current and high dv/dt withstand capability.

We can make 2 pins and 4 pins for this product. JFQP series can be alternative for Epcos MKP B32774~B32778, Vishay MKP1848C etc.

jb Capacitors not only have stand tantalum capacitors, but also it has Ultra-Low ESR Conductive Polymer Chip Tantalum Capacitors. It is jb’s JTD series. This series contains the feature like below. 

 High frequency capacitance retention
 Volumetric efficiency
 High ripple resistance
 Extremely long life and polarized.
 Attractive to design-in engineers for space 
 Suitable for high frequency applications.
 High reliability and heat resistance.

Based on the above features, it can be used on DC/DC converters, notebook PCs , portable electronics , telecommunications (mobile phone and base station ), displays ,SSD,HDD and USB.
Though, this is a new series in jb Capacitors Company, but it also have the fast lead time, competitive price and high quality. jb can provide customized items too.

jb Capacitors launched a new series, called JFYY. It is a Y2 Metallized Polypropylene Film Capacitors. It has below features, and it can be used on line to ground, line-by-pass, antenna coupling interference suppression circuit, etc. It has withstanding overvoltage stressing, excellent active and passive flame resistant abilities.

Though this is new series in jb Capacitors, but the quality and lead time is all high class within the company. The lead time is from 5~7 weeks. We have strict quality control. And, as the same as other series, it also can customized, if you have any size requirement or capacitance requirement, please contact us directly.

A Super Capacitor is double-layer capacitors that are high-capacity capacitors. They have higher capacitance and lower voltage limits than other types of capacitors.
