The MMF Series Melf Metal Film Resistors are
manufactured using a vacuum sputtering system
to deposit multiple layers of mixed metal
alloys and passivative materials onto a carefully
treated high grade ceramic substrate. After
a helical groove has been cut in the resistive
layer, SMD enabled structure. The resistors are
coated with layers of blue color lacquer.
For resistors operated in ambient temperatures above 70°C, power rating must be derated
in accordance with the curve below.

Where can I download the BSP for powerpc in vxworks 5.5?
I downloaded it from a website via FTP, but it is only 12MB and cannot be used. Emule has no source code now. Where else can I download it? Thank you very much!...

What should I do when the PCB has a large current?
1. In the circuit, multiple power tubes are used to make the power reach 3000W. However, after reaching 3000W, the current will reach 100A. How to solve this high current 100A problem on the PCB board...
