HOW TO APPLY RESISTORS CORRECTLY:
  • THE CHARACTERISTICS OF RESISTOR HAVE RELATIONS TO TEMPERATURE MOISTURE AND VOLTAGE.
  • THE RATING OF RESISTOR IS SPECIFIED ON THE BASIS OF TEMPERATURE.
  • THE POWER RATING OF RESISTOR IS ALL SPECIFIED WITH A DIRECT- CURRENT (D.C.) CONTINUOUS WORKING VOLTAGE OR SINE-WAVE ROOT- MEAN-SQUARE (RM S) CONTINUOUS WORKING VOLTAGE AT COMMERCIAL- LINE FREQUENCY.
  • THE TESTS REGARDING CHARACTERISTICS OF RESISTOR, IS PRINCIPALLY SPECIFIED ON THE BASIS OF MOISTURE.
  • MAXIMUM RATED VOLTAGE AND MAXIMUM OVERLOAD VOLTAGE ARE LIMITED FOR EACH STYLE OF RESISTOR (1)GENERALLY, RATED VOLTAGE=√P.R WHERE, E=VOLT, P=WATT, R=OHM. (2)GENERALLY, OVERLOAD VOLTAGE ET=√PRx2.5, APPLICATION TIME=5 SECS.
    NOTE/MAX. RATED AND MAX. OVERLOAD VOLTAGE ARE SPECIFIED IN EACH SPECIFICATION, SO IF THE VOLTAGE VALUE COMPUTED, IS OVER THAN SPEC 1-FIED VOLTAGE VALUE, THE SPECIFIED VALUE SHOULD BE APPLIED TO RESISTOR...
  • IN THE COMPLICA TED OR HIGH DENSITY CIRCUIT, IT IS RECOMMENDED THAT THE WATTAGE OR OHMIC VALUES OF RESISTOR SHOULD HAVE A LARGE REDUNDANCY FROM A VIEW POINT OF RELIABILITY.
  • IT IS NECESSARY THAT THE HANDLING OR WIRING OF RESISTOR TO THE CIRCUIT, IS CAREFULLY AND PLEASE DO NOT INFLICT ANY STRESS TO RESISTOR WITH OVER, HEATING APPOLICTION.
  • TO RISE THE RELIABILITY OF RESISTOR, IT IS BETTER TO PRERER RESISTOR WITH UNFORM QUALITY THAN TAKING RESISTOR MET WITH SEVERE SPECIFI-CATION.
  • TO RISE THE STABILITY OF RESISTOR, IT IS VERY IMPORTANT TO TAKE RESIS-TOR MET WITH CIRCUIT CONDITIONS AND IS ALSO ECONOMICAL NO TO HAVE UNREASONABLE DESIGE FROM A POINT OF PRICING OF RESISTOR.
  • GENERALLY, FAILURE OF RESISTOR TAKES A CONCENTRATED TREND IN THE IMPULSE CIRCUIT WITH COMPLICATED PULSE WAVE FORM OF LC CIRCUIT GENERATED HIGH VOLTAGE WITH TRANSIENT PHENOMENA, THEREFORE, IT IS VERY IMPORTANT FOR DESIGNERS TO CONSIDER, THESE CONDITIONS IN THE CIRCUIT DESIGN, IF THE RESISTOR IS APPLIED IN THESE CIRCUIT.
