Size:200 Pieces Resistance is a current limiting source and a very basic need when we work in field of electronics. The electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor. The inverse quantity is electrical conductance, the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with the notion of mechanical friction. The SI unit of electrical resistance is the ohm (Ω), while electrical conductance is measured in siemens (S) For basic guidelines on using resistors,see the technical reports issued by Japan Electronics and Infomation Technology Industries Association.JEITA RCR-2121A. " Guideline of notabilia for fixed resistors for use in electronic equipment (Safet y application Guide for fixed resistoros for use in electronic equipment)" Supplementary to notes *1: When resistor is to be exposed to a transient load (excessive large load,such as pulse), m ount the resistor on your product and check the condition and evaluate the re sult. Constant application of a volt age above the rated voltage will degrade the performance and reliabillity of the resistor . Do not apply a voltage exceeding the ra ted voltage across any RHOM resistors. *2: or the limiting element voltage, whichever smaller, is the rated voltage.
