jb JRB – хорошие конденсаторы по отличной цене от jb Capacitors

Серия JRB – это новая серия электролитических конденсаторов в складской программе Компэл от известного производителя JB Capacitors. Эти конденсаторы предназначены для самого массового сегмента потребительской электроники, имеющие базовые параметры рабочего температурного диапазона от -40℃ до +105℃ и времени наработки на отказ в 2000 часов.

Такое соотношение характеристик позволяет предложить производителям электроники хорошее 
соотношение цена/надежность. Применение электролитических конденсаторов с базовой
наработкой в 2000 часов позволяет существенно снизить стоимость конечного продукта при
больших производственных объемах. Конденсаторы JRB являются аналогом и отличной
альтернативой таким сериям конденсаторов, как EHR от Hitano, TM от Jamicon, RD от Samwha, SH от Yageo. Основные диапазоны электрических параметров, в рамках которых могут быть выбраны конденсаторы серии JRB представлены ниже:

Рабочий диапазон температур -40℃ ~ +105℃ -25℃ ~ +105℃
Рабочее напряжение 6,3 ~ 100 В 160 ~ 450 В
Номинальная емкость 0,1 ~ 22000 мкФ 0,47 ~ 470 мкФ
Начальный допуск +/- 20%

Полная линейка радиальных миниатюрных электролитических конденсаторов производства jb Capacitors состоит из 5 серий и включает в себя решения с наработкой до 10000 часов:

And we will update the RoHS2.0 for all film capacitors and SMD type aluminum electrolytic capacitors 

jb capacitors are working more hard to get the best support for our customers, we are looking forward to win more & more market shares together with our customers. 

We welcome more win-win cooperations. 

jb Tells You Some Information Regarding Aluminum Electrolytic Capacitors

The electrolytic capacitor has been in use for many years. Its history can be traced back to the very early days or radio around the time when the first broadcasts of entertainment were being made. At the time, valve wireless sets were very expensive, and they had to run from batteries. 
However with the development of the indirectly heated valve or vacuum tube it became possible to use AC mains power.

While it was fine for the heaters to run from an AC supply, the anode supply needed to be rectified and smoothed to prevent mains hum appearing on the audio. 
In order to be able to use a capacitor that was not too large Julius Lilienfield who was heavily involved in developing wireless sets for domestic use was able to develop the electrolytic capacitor, allowing a component with sufficiently high capacitance but reasonable size to be used in the wireless sets of the day.

Electrolytic capacitor symbols

The electrolytic capacitor is a form of polarised capacitor. The electrolytic circuit symbol indicates the polarity as it is essential to ensure that the capacitor is fitted into the circuit correctly and is not reverse biased.

Circuit symbols used for polarised capacitors like the electrolytic capacitor

There is a variety of schematic symbols used for electrolytic capacitors. The first one '1' is the version that tends to be used in European circuit diagrams, while '2' is used in many US schematics, and '3' may be seen on some older schematics. Some schematic diagrams do not print the "+" adjacent to the symbol where it is already obvious which plate is which.

jb Configuration of Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, usually simply called an electrolytic capacitor (e-cap), is a capacitorwhose anode (+) consists of pure aluminum foil with an etched surface, covered with a uniformly very thin barrier layer of insulating aluminum oxide, which operates as a dielectric. 

The electrolyte, which covers the rough surface of the oxide layer, operates as the second electrode, the cathode (-). 

E-caps have the largest capacitance values per unit volume compared to the two other main conventional capacitor families, ceramic and plastic film capacitors, but articulately smaller capacitance than similar sized supercapacitors.

jb Tells You What are Electrolytic Capacitors?

An electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. 
Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal. 
The benefit of large capacitance in electrolytic capacitors comes with several drawbacks as well. 
Among these drawbacks are large leakage currents, value tolerances, equivalent series resistance and a limited lifetime. 

Electrolytic capacitors can be either wet-electrolyte or solid polymer. They are commonly made of tantalum or aluminum, although other materials may be used. 
Super capacitors are a special subtype of electrolytic capacitors, also called double-layer electrolytic capacitors, with capacitances of hundreds and thousands of farads.  

This article will be based on aluminum electrolytic capacitors. These have a typical capacitance between 1µF to 47µF and an operating voltage of up to a few hundred volts DC. 
Aluminum electrolytic capacitors are found in many applications such as power supplies, computer motherboards and many domestic appliances. Since they are polarized, they may be used only in DC circuits.
