INTRODUCTION
Vishay Military Established Reliability resistors are available
in resistance values from 4.99
Ω
through 121 kΩ and for
tolerances from ± 0.005 % to ± 1.0 %. The same resistors are
also available as a non-qualified product for customers
desiring higher or lower resistance values and the same or
better performance capabilities. (See table 2) Both the
qualified and the non-qualified version are manufactured on
the same production line facilities and are subjected to the
same process, lot control, conditioning, and GRP A (100 %)
screening. Qualified versions receive additional MIL Group B
and C testing.

“Commercial and Government Entity”
Formerly “FSCM”
The response of military and non military grade resistors to environmental stresses can be made better by “Improved
Performance Testing” (IPT). The IPT part will see burn-in and cycling that removes the “knee” from the normal drift of non IPT
parts. (See Table 4 for the improvement to expect in military parts when calling for Vishay recommended screening). Users
should be aware that IPT testing renders the part non QPL and so a 3XXXXX part number will be assigned by Vishay. Consult
Applications Engineering for details and ordering advice.

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]
