jb Tell You Some Aluminum Electrolytic Capacitors' Features and Application

Aluminum electrolytic capacitors have always been a popular choice for power supply, due to its low cost. However, their life have limited , and easy to influenced by extreme conditions ,main problem is high temperature and low temperature. Aluminum Electrolytic capacitors is made by aluminum foil and electrolyte. This electrolyte will evaporate during the life of the capacitor, it will change its electrical properties step by step. If the capacitor fails, it will be violent reactions: release flammable, corrosive gases.

The electrolyte evaporation's speed all depend on capacitor temperature. Operating temperature dropped 10 degrees, the capacitor's life will be doubled. Usually, the capacitors' life usually means under maximum rated temperature. The typical rated life is 1000 hours at 105 degrees Celsius. In the application of LED which requirement life time 25000hours, the aluminum electrolytic capacitor will have problem. Cause if want to reach to 25000hours, the working temperature should not more than 65°C. But LED working temperature can reach to 125°C at most. Though some famous manufacturer declare their can reach. but aluminum electrolytic capacitors still is limited LED Lamp's life.

How to solve this problem? First, you may be chose to increase the rated voltage of the capacitor, to reduce the probability of electrolyte failure. However, the way will make the capacitor equivalent series resistance (ESR) more higher than before. Since the capacitor will generally have a high ripple current stress, so this high internal resistance will bring additional power consumption and increase the capacitor temperature. Failure rate will increases by increasing temperature. When the capacitor temperature is low, ESR increased dramatically. In this case,-40°C, the resistance increases by orders of magnitude. This will affect the power performance in many ways. If the capacitor is used for output of a switching power supply, the output ripple voltage was increased by orders of magnitude. Further, in the above zero frequency and the output capacitor ESR is formed, which allows an order of magnitude increase in the loop gain, which affects the control loop. This produces a stable oscillation power. In order to meet this strong vibration, the control loop will usually make a huge compromise in terms of space and operate at higher temperatures.

In short, the aluminum electrolytic capacitor is typically the lowest cost option. However, you will need to determine whether the application of its shortcomings adversely affected. Through its operating temperature you need to consider their longevity. meanwhile, you should appropriately reduce the rated voltage, so that you can achieve the lowest temperatures, and thus get the longest life. Finally, you need to understand the ESR range must be used so that you can properly design the control loop, to meet the ripple specifications.

 

jb Capacitors Releases JYA Y2 CE 300VAC Safety Standard Recognized Capacitors

Class-X and Class-Y capacitors are safety-certified capacitors generally designed and used in AC line filtering in many electronic device applications. These safety capacitors are also known by other names. Class-X and Class-Y capacitors help to minimize the generation of EMI/RFI and the negative effects associated with received EMI/RFI.

One of safety-certified capacitors, JYA Class Y2 CE types capacitors, which are typically produced out of ceramic and paper dielectrics, are used with voltages up to 300Vac and a peak test voltage of 5 KV. JYA Y2 class certified product (basic insulation product) is a cross reference to Murata DE series.

They are designed to suppress any noise from an electronic device by reducing the input impedance of the device, and are connected between line and chassis; if they are short-circuit, they create a risk of shock to the user, but there will be no fatal electric shock hazard.

jb Capacitors Tell You Difference Between Electrolytic and Ceramic Capacitor

Electrolytic VS  Ceramic Capacitor

A capacitor is an electrical component which is able to store electrical charges. Capacitors are also known as condensers. Ceramic capacitors and electrolytic capacitors are two main types of capacitors that are widely used in electrical and electronic components. The ceramic capacitor uses a thin ceramic layer as the dielectric medium whereas the electrolytic capacitor uses an ionic liquid as one of the sheets of the capacitor. In this article, we are going to discuss what electrolytic capacitor and ceramic capacitor are, their properties, and finally a comparison between electrolytic capacitor and ceramic capacitor and summarize the difference between ceramic capacitors and electrolytic capacitors.

What is a Ceramic Capacitor?

In order to understand what a ceramic capacitor is one must first understand what a capacitor is in general. Capacitors are devices that are used to store charges. Capacitors are also known as condensers. Commercially used capacitors are made of two metal foils with a dielectric medium in between them rolled into a cylinder. The capacitance is the main property of a capacitor.
The capacitance of an object is a measurement of the amount of charges that object can hold without discharging. Capacitance is a very important property in both electronics and electromagnetism. Capacitance is also defined as the ability to store energy in an electric field. For a capacitor, which is having a V voltage difference across the nodes and the maximum amount of charges that can be stored in that system is Q, the capacitance of the system is Q/V, when all are measured in SI units. The unit of the capacitance is farad (F). However, as it is inconvenient to use such a large unit, most of the capacitance values are measured in nF, pF, µF and mF ranges.
In a ceramic capacitor, a thin ceramic layer act as the dielectric medium. A ceramic capacitor has no polarity. Ceramic capacitors are classified into three main classes. Class I capacitors have better accuracy and low volumetric efficiency whereas class III capacitors have low accuracy and high volumetric efficiency.

What is an Electrolytic Capacitor?

An electrolytic capacitor is made by having an ionic liquid as one of the conducting plates of the capacitor. Most of the electrolyte capacitors are polarized. This means the voltage at the anode cannot become negative relative to the voltage applied to the cathode. If this happens, the capacitor becomes corrupted by ion exchange. Electrolytic capacitors are famous for having higher volumetric efficiency. This means a small capacitor is able to hold larger amount of charges than a ceramic capacitor of the same size.

What is the difference between Ceramic Capacitor and Electrolytic Capacitor?

• Ceramic capacitor has two metal sheets at the terminals to store charges. The electrolytic capacitor has one metal sheet and an ionic liquid as the two terminals.
• Electrolytic capacitors are capable of holding more charges per volume than ceramic ones.
• Most of the electrolyte capacitors are polarized, but ceramic capacitors are never polarized
