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. 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.

What to do? The temperature rise of the switching power supply transformer is too high: [p=25, null, left][color=rgb(62, 62, 62)] In actual application, excessive temperature rise often occurs in two aspects: the MOS tube of the power transformer and the transformer design itself.
