BA6872资料

１

1、 钢铁材料的规格，首先分为铁和钢两大类，进而铁又分为生铁，铁合金和铸铁。钢又分为普通钢，特殊钢，铸锻钢。普通钢再按其形状不同，细分为条钢、厚板、薄板、钢管、线材及钢丝。特殊钢按其性质细分为调质钢，工具钢及特殊用途钢。

钢铁材料代号也按上述规格分类，原则上由下列三个部分组成：

第（1）部分表示材质

第（2）部分表示规格名称或产品名称

第（3）部分表示种类

例：

S S 41 S UP 6

(1) (2) (3) (1) (2) (3)

⑴使用英语或罗马字的第一个字母或化学元素符号表示材质，钢铁材料大部分是以S（Steei：钢）或F（Fvvam铁）的代号为首。

例外：Simn 硅锰合金 MCr金属铬等合金类 SXX（Sisilicon xx：数字）冷轧硅钢带。

⑵使用英语或罗马字的第一个字母表示不同的板，管，棒，丝等产品的形状，种类和表示用途的代号组合起来表示产品名称。跟在S或F后面的记号，大多数按下列分组标记，P：（Plate）薄板，U：（Use）特殊用途，T：（Tube）管，C：（Castting）铸件，K：（Kogu）工具，F：（Forging）锻造。W：（Wire）线材，丝。

例外：

Ⅰ）合金结构钢一组（例如镍铬钢）则象SNC那样标注添加元素符号。

Ⅱ）普通钢钢材中的条钢，厚板（例如锅炉用的钢材）则象SB那样标注表示其用途的英语第一个字母。

⑶表示材料的种类，最低抗拉强度或屈服点，但机械结构用钢，用含碳量和主要合金元素量代号的组合来表示。

例：1、第一种 A：A种或A号，2A：第2种A级，24：抗拉强度或屈服点。

附注：在钢铁材料代号之外，当需要对形状和制造方法等进行代号化处理时，可在种类代号之后附加下列符号或代号。

例：SM58Q表示第5种焊接结构用轧制钢材，即经过淬火，回火处理过的那种。

BA12001B / BA12003B / BA12003BF / BA12004BStandard ICsHigh voltage, high current Darlington

transistor array

BA12001B / BA12003B / BA12003BF / BA12004B

The BA12001B, BA12003B, BA12003BF, and BA12004B are high voltage, high current, high sustain voltage transistorarrays consisting of seven circuits of Darlington transistors.Because it incorporates built-in surge-absorbing diodes and base current-control resistors needed when using inductiveloads such as relay coils, attachments can be kept to a minimum.With an output sustain voltage as high as 60V and an output current (sink current) of 500mA, this product is ideal for usewith various drivers and as an interface with other elements.

!ApplicationsDrivers for LEDs, lamps, relays and solenoidsInterface with other elements

!Features1) High output current. (IOUT=500mA Max.)2) High output sustain voltage. (VOUT=50V Max.)3) Seven Darlington transistors built in.4) Built-in surge-absorbing clamp diode. (Note : Refer to the “Reference items when using in application.” )
