Do you have an idea on jb capacitors company series? Generally speaking, jb capacitors company has many popular series, today I will show you JFB- MKT film capacitors and JFV-X2 MKP film capacitors first.

JFB- Metallized Polyester Film Capacitors , is always among our key products due to its unbeatable price and short lead time. It can cross to Vishay MKT468, Epcos B32591~32594, Panasonic ECQE, ECQV, Pilkor PCMT 369.  It mainly uses in filtering, DC blocking coupling, general communication equipment, bypass and energy reservoir. Except that, it also can be used on automatic phase reversal module, AC receiver, HID ignitors, power adaptor, flashing light and lighting.

Our another strong point, JFV-X2 Metallized Polypropylene Film Capacitors, also called X2 interference Suppression polypropylene film capacitors, has the advantage on price competition in most market. That may cross to Kemet & Arcotronics:  R46, Philip Vishay: MKP3382, Epcos: B81 130, Evox Rifa: PHE840M. Most of our customers use it in power supply, lighting, LED driver, fans, power meter, motor control, ignitor, filter, heater controller, microwave, battery charger, and so on.

When a capacitor discharges its charge throught a resistor, the charge of the capacitor decreases with time. The decreasing charge follows an exponential decay curve.

A super capacitor is also known as a double-layer capacitor. It polarizes an electrolytic solution to store energy electro statically. Though it is an electrochemical device, no chemical reactions are involved in its energy storage mechanism. This mechanism is highly reversible, and allows the ultra capacitor to be charged and discharged hundreds of thousands of times.

A super capacitor can be viewed as two non reactive porous plates, or collectors, suspended within an electrolyte, with a voltage potential applied across the collectors. In an individual super capacitor cell, the applied potential on the positive electrode attracts the negative ions in the electrolyte, while the potential on the negative electrode attracts the positive ions. A dielectric separator between the two electrodes prevents the charge from moving between the two electrodes.

For capacitors in parallel

Capacitors in a parallel configuration each have the same applied voltage. Their capacitances add up. Charge is apportioned among them by size. Using the schematic diagram to visualize parallel plates, it is apparent that each capacitor contributes to the total surface area.

Several capacitors in parallel.

For capacitors in series

Connected in series, the schematic diagram reveals that the separation distance, not the plate area, adds up. The capacitors each store instantaneous charge build-up equal to that of every other capacitor in the series. The total voltage difference from end to end is apportioned to each capacitor according to the inverse of its capacitance.

Several capacitors in series.

The entire series acts as a capacitorsmaller than any of its components.

Capacitors are combined in series to achieve a higher working voltage, for example for smoothing a high voltage power supply. The voltage ratings, which are based on plate separation, add up. In such an application, several series connections may in turn be connected in parallel, forming a matrix. The goal is to maximize the energy storage utility of each capacitor without overloading it.

When you use a capacitor after prolonged storage. you should pay attention.

An Aluminium Electrolytic Capacitor which has been stored for a long period of time tends to give increased leakage current.

Accordingly, whenever you use a capacitor that has been stored a while, make sure to gradually increase the voltage to the rated value. Since the leakage current tends to be higher with higher storage

atmosphere temperatures. store the units at a location with storage temperatures of -40 to 40C which is not exposed to direct sunlight.
