FPM series is a group of nonflammable, high performance metal film fixed resistors. By applying selected flame-overload burning-resisting resin on our regular metal fixed resistors, those resistors improve the safeness of various kinds of electronics devices and instruments and having excellent electrical performance.
REQUIREMENTS | CHARACTERISTICS | TEST METHOD |
Non-Combustibility | MIL-STD-202 Mothod 111 | |
Flame Resistance | ||
Not burns continuously for more than 5 seconds. Overload Burning Resistance Not fume under the overload of less than 5 times of rated power. | JIS C5202 7 12 | |
The volume of fumes emitted under the overload of more than 5 times of rated power is less than that of stilled fumes emitted by one cigarette. | ||
During the test the height of fumes does not over 3mm and the burning does not continue for more than 3 seconds. | EIAJ-RC 2658 5 1 | |
