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.

Supercapacitors used in high-power power supplies and large-scale industrial power supplies. Now we have found their use in products of various sizes, especially portable devices. Supercapacitors are well-known for their capacitance values up to thousands of farads and fast charging and discharging rates.

Due to the ability to store large amounts of electrical energy for a long time, the supercapacitor behaves more like a battery than a standard capacitor. In fact, as technology advances, they will replace rechargeable batteries in many products, from computers, digital cameras, mobile phones to other handheld devices.

Today,Many countries in the world are actively carrying out research and development related to supercapacitors. The main manufacturers are: MAXWELL and Ioxus in the United States, EL NA and PANASONIC in Japan, LS Mtron and Vina Technology in South Korea, and ECOND in Russia. jb Capacitors Company of China brand, it’s a nice choose:

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

 

Jb sells X2 Met Polypropylene Film Capacitor - 85 °C / 85 % RH Temperature Humidity Bias—JFWT series.

JFWT is THB X2 series, which has high stability of capacitance under severe ambient condition, high temperature and high humidity.
