If you are using SCR, Mundorf MKP, Jantzen, welcome to try our audio capacitor, you would be surprised for our good performance, especially save lots of cost.

We have cooperation with many famous Audio manufacturers, please trust our high quality standard. Please feel free to send us RFQs to info@jbcapacitors.com

jb offers different type of passive component including capacitor and varistor. Not only capacitors, we can provide high quality for Varistor.
It is Zinc Oxide Varistors JVA Series, A varistor is an electronic component with an electrical resistance that varies with the applied voltage.

Its features are on below:
* Round Varistor element, leaded.
* Low leakage current.
* Excellent Voltage ratio, Wide Voltage & energy ratio.
* High performance in clamping voltage characteristics.
* Low standby power and no follow on current.

It can be used on Multi Meter, LED Driver, application in protecting power and signal level electrical circuits against dangerous voltage surges. If you have more questions, please contact jb sales directly.

We design and manufacture high quality Zinc Oxide Varistors Series.  A varistor is an electronic component with an electrical resistance that varies with the applied voltage.
Varistors currently have widespread application in protecting power and signal level electrical circuits against dangerous voltage surges.
Zinc oxide varistors are electronic ceramic materials whose electrical behavior is dominated by grain-boundary interface states.

They exhibit a highly nonlinear current-voltage relation with a 5% change in voltage serving to increase the current flow an order of magnitude or more.

If you need this products, please mail us freely. We will be glad to offer you the price information and the most suitable products for you.

A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes.
The composition of the ceramic material defines the electrical behavior and therefore applications.

What are the benefits for using multilayer ceramic capacitor? One of the advantages is that multilayer ceramic capacitors have excellent frequency characteristics, thanks to their low equivalent series resistance (ESR). The term “ESR” refers to the resistance component of a capacitor’s internal electrodes, etc.

Multilayer ceramic capacitors (MLCCs) are generally the capacitor of choice for applications where small-value capacitances are needed. They are used as bypass capacitors, in op-amp circuits, filters, and more.
How are multilayer ceramic capacitors made? A multilayer ceramic capacitor is completed as a chip, mainly through the following eight forming processes.

Processes:
• Printing of the internal electrodes on the dielectric sheet.
• Stacking of the dielectric sheets.
• Pressing process.
• Cutting process.
• Sintering process
• Applying and baking the outer electrodes.
• Plating process.

As usual, jb Capacitors Company offers wide range capacitors. One of jb’s strong series is JFW - X2 Metallized Polypropylene Film Capacitor (310VAC). It is continually being a strong series with unbeatable price and quality on this market. Further, JFW is upgraded, it can meet +105C originally. But, now, it can meet +110C.

The quality of JFW is very good, it has it has safety approval of VDE, ENEC and UL approvals. In other words, there is certain quality assurance. Furthermore, it has fast delivery time with stable supply. JFW can be used on Across-the-line, interference suppression circuit, Fire Alarms, Call systems, induction loops and so on.

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.

Do you know that we have Polymer Chip Tantalum Capacitors? Our JTD is SMD Conductive Polymer Chip Tantalum Capacitors. jb is trying to expand our market share, so we launched this series.

  Supercapacitors are widely used in high-power power supplies and large-scale industrial power systems. They are now found in products of various sizes, particularly portable devices. Known for their capacitance values reaching thousands of farads and fast charging and discharging rates, supercapacitors are essential components in many applications.

Thanks to their ability to store large amounts of electrical energy for extended periods, supercapacitors function more like batteries than traditional capacitors. As technology progresses, supercapacitors are expected to replace rechargeable batteries in many products, including computers, digital cameras, mobile phones, and other handheld devices.

Many companies around the world are actively engaged in research and development of supercapacitors. Some of the leading manufacturers in the industry include well-established brands in the market.

jb Capacitors offers the following high-quality supercapacitors:
JGA - 5.5V Standard Coin Type Super Capacitors
JGM - 5.5V 7.5V Combined Type Super Capacitors
JGY - 5V 7.5V Combined Type Super Capacitors
JGZ - 2.7V 3V Low ESR Radial Snap in Screw Type Super Capacitors
