Ei28 core datasheet

設計前最好都先看一下相應的datasheet,確認一下簡單的參數。無論是選用PI的集成,或384x或OBLD等分立的都需要參考一下datasheet。一般datasheet里都會附有簡單的電路原理圖,這些原理圖是我們的設計依據。

Core size: Actually, the initial selection of the core is bound to be crude since there are too many variables. One way to select the proper core is to refer to the manufacture's core selection guide. If there is no proper reference, use the table 2 as a starting point. The core recommended in table 1 is typical for the universal input - Contains over 50 million semiconductor datasheets. - More than 60,000 Datasheets update per month. - More than 450,000 Searches per day. - More than 24,700,000 Impressions per month. - More than 12,600,000 Visits per month all around the world.

得到ap值之后,可能有非常多的变压器都符合需要,这是首先需要考虑结构尺寸的限制,特别是高度与宽度的限制。比如efd30与ei28的ap值同样都是0.6cm4左右,但efd30的高度小很多,更适合与扁平化的电源中,而ei28对于紧凑型电源则显得更重要。 61阅读,据和语音服务的公司。事实上它们已经被逼到了墙角,不得不开始创新。 61阅读提醒您本文地址:指南设计创始人兼设计总监 周佚098不同的设计专业之间的界线开始模糊,出现融合的趋势。 Автор: нас рать 2.5.2009, 7:36 стабилитрон при правильном трансе и нагрузке блока всего 20вт сильно греццо не должен, да и желательно так разводить плату, чтобы под ним побольше фольги было для охлаждения.

If the placeholder is “A”, means the dimension value is over 100mm, then the unit is cm; EFD38=EFD38 core; ⑤ External Dimensions (L×H). Four numbers, the former two numbers show length, the later two numbers show height, Unit: mm or cm which lies on the item ④; ⑥ Configuration. The 1623-2 Earth Ground Tester (Tester or Product) is a compact, field-rugged instrument that performs all four types of earth ground measurement. Specifically, the Tester is able to measure earth ground loop resistances using only clamps – called Stakeless testing. This method doesn’t require the use of earth ground stakes or the EI-core is characterized by less core loss, high yield-resistance and high permeability, and ferrite EI core is easier to achieve high voltage electrical.Application of EI-core datasheet search, datasheets, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes and other semiconductors.
