Termination Code
The above part number refers to a 800 B Series (case size B) 91 pF capacitor,
J tolerance (±5%), 500 WVDC, with T termination (Tin Plated over Nickel Barrier Termination, RoHS Compliant), laser marking and tape and reel packaging.
ATC accepts orders for our parts using designations
with
or
without
the
“ATC” prefix. Both methods of defining the part number are equivalent,
i.e., part numbers referenced with the “ATC” prefix are interchangeable to
parts referenced without the “ATC” prefix. Customers are free to use either
in specifying or procuring parts from American Technical Ceramics.
For additional information and catalogs contact your ATC
representative or call direct at (+1-631) 622-4700.
Consult factory for additional performance data.

C++ 属于面向对象的编程语言，OOP的思想不必多说，特别对于复杂的软件工程来说，利用OOP绝对是事半功倍，相对于传统的C来说； 当然用C来写单片机程序无可厚非，已经延续了一个传统，从大学时学的开始到工作岗位，好多人都是一直用C来做，但是既然Keil支持C++编译， 可以用C++来编写你的代码，可以利用高级语言来结构化，清晰化你的程序，为嘛不用呢！哈哈，个人看法！下面进入正题： C+...[详细]
