power vitreous enameled resistors

.Smoke emitted from non-flammable resistors on initial use in powered circuits is a normal phenomenon and the component can be
safely utilized.
2.All resistors manufactured by our company comply with the U.S. UL-94 non- flammability test, Class V-0, a continuous combustion
period of zero seconds.
3.Never use organic solvents to clean non-flammable resistors.
4.Non-flammable resistors cannot be utilized in oil.
5.Non-flammable resistor cannot be used in high frequency machinery because of the inductance produced by the windings. A suitable
type of resistor must be selected. Contact us for details.
6.In applications where resistors are subject to intermittent current surges and spikes, be sure in advance that the components selected are capable of withstanding brief durations of increased load.
7.Do not exceed the recommended usable load. Resistors must used within the rated voltage range to prevent the shortening of service
life or failure of the wound resistance elements
8.Minimum load. Resistors must be utilized at 1/10 or more of the rated voltage to prevent poor conductance due to oxidation build-up.
9.Although the hardness exceeds that of a 3H pencil lead, do not nick the resistor coating with screw drivers or other pointed objects.
10.Avoid touching non-flammable resistors in operation; the surface temperature ranges from approximately 350J to 400J when
utilized at the full rated value. Maintaining a surface temperature of 200J or less will extend resistor service life.
11.Keep temperature from rising by choosing a resistor with a higher rated capacity; do not use a component having the exact load value
required. For considerations of safety in extended period applications, the resistor rating should be more than four times higher than
the actual wattage involved, but never use a resistor at less than 25% of its rated power.
12.Application and Placement: Wire-wound resistors use different gauges of wire as resistance elements. Sometimes the gauge is extremely thin (finer than a strand of human hair) and very susceptible to breakage in environments containing salts, ash, dust and corrosives. Avoid utilization in such environments. Do not install in dusty areas because the accumulation will cause shorts and poor conductance
