Unique Selling Points:The resistance is high precision. May be provide products of the precision:±1%, ±2%. On the surface they are painted or glazed. And the retardation flame conform to the national standard. They are used extensively printed circuit board installation. Used in DC or low frequency AC circuits. If used in high frequency circuit, it shall order non-inductive resistor, need to declare when you order it. Non-inductive resistor with "N" in front of the product logo.
