Note IV use:

: (1) Non-flammable resistors used for the first time power will produce smoke situation is normal and please feel at ease to use
(2) The Company is not flammable paint in the United States UL-94 incombustibility test V-0 rating, burning to continue the time to 0 seconds
3 resistant to cleaning, non-flammable resistors can not use organic solvent cleaning
4 oil which is not flammable resistors can not use oil which
High-frequency mechanical incombustible Resistor wirewound and inductance, can not be used in the high-frequency mechanical, subject to the choice of appropriate resistor, and we discuss
Instantly enhance (surge) current pulse (pulse): required Inca large load in a short period of time must be confirmed instantly enhance the resistance (surge) characteristics
Practical load: In order to prevent the fatigue resistance of the life of the alloy wire, the use of electricity remain in the fixed grid voltage reduce the curve
Minimum load rate: In order to prevent oxidation caused by exposure to adverse growth generated over time, use the freeze power more than 1/10 power
. Incombustible resistor coating insulating film hardness higher than 3H pencil hardness, but do not portray a screwdriver and other sharp objects
10 non-flammable resistors used in the full load rating, the surface of the high temperature about 350 ℃ -400 ℃, please do not touch the hand to long-term use for the maintenance of the resistor, keep the resistor surface temperature rise below 200 ℃
11 to suppress the temperature rise requires considerable tolerance margin, do not use exactly the full load rating. Prolonged use of its security concerns, the wattage must be greater than four times the rated power, and try to use less than 25% of the fixed grid power
12 and place Note: Sometimes the line-wire resistive, depending on the resistance of the use of diameter is very thin (thinner than hair) resistance line. Environment from salt, more than factors such as humidity, dust, corrosive, and they often result in fracture diameter, avoid use in such an environment. Please note not to let the dust of the surface of savings. If dust buildup will cause breakage or poor contact
