traveling Contents of the module: 10 of the resistor It is represented in units of percentage In case of band resistor, the decimal multiplier will be assigned to the fourth band and tolerance value will be assigned to the fifth band Finally in case of a band resistor, the last band (i.e 6th band) represents temperature coefficient .The sixth temperature coefficient band increases the precision of the resistance value Temperature coefficient tells us the behavior of resistor under different heating conditions (means the variation in resistance values under normal conditions and over heated conditions) It is defined in units of ppm/K Resistor Color Code Chart We have presented charts below – which are exactly resistor color code charts for band, band and band resistors respectively 99 4-Band Resistor Color Code Identification Let us consider the color code for the resistor with the bands BROWN-BLACKRED-GOLD Brown corresponds to the value ‘1’ in the color chart Black represents ‘0’ and Red represents the multiplier ‘100’ Thus the value of the resistance to the corresponding color code is 10*100 = 1000 ohms or kilo ohm with the tolerance band being Gold which represents a tolerance of +/- 5% Thus the actual value of the kilo ohm can be between 950 ohms and 1050 ohms Band – First digit value of resistor Band – Second digit value of resistor Band – Decimal Multiplier Band – Tolerance Value 100 5-Band Resistor Color Code Identification Let us consider the color code for the resistor with the bands YELLOW-VIOLETBLACK-BROWN-GREY Yellow corresponds to the value ‘4’ in the color chart Violet represents ‘7’ and Black represents the value ‘0’ Brown represents the multiplier ‘10’ Thus the value of the resistance to the corresponding color code is 470*10 = 4700 ohms or 4.7 kilo ohm with the tolerance band being Grey which represents a tolerance of +/- 0.05% Band – First digit value of resistor Band – Second digit value of resistor Band – Third digit value of resistor Band – Decimal Multiplier Band – Tolerance Value 101 6-Band Resistor Color Code Identification Here also, if we can consider the same color code used for the 5-band, with an additional temperature coefficient band with a blue color This shows that the resistor has a value of 4.7 kilo ohms, with tolerance +/- 0.05% and with a temperature coefficient of 10 ppm/K 102 Band – First digit value of resistor Band – Second digit value of resistor Band – Third digit value of resistor Band – Decimal Multiplier Band – Tolerance Value Band – Temperature Coefficient Note: - Nowadays with advances in printing technology, it’s possible to print numeric values on small components as well If you look at an SMD resistor (surface mount), you will see the resistance value printed directly on the surface of the resistor Calculating Resistor Values The Resistor Colour Code system is all well and good but we need to understand how to apply it in order to get the correct value of the resistor The “left-hand” or the most significant coloured band is the band which is nearest to a connecting lead with the colour coded bands being read from left-to-right as follows: Digit, Digit, Multiplier = Colour, Colour x 10 colour in Ohm’s (Ω) For example, a resistor has the following coloured markings; Yellow Violet Red = = x 102 = 4700Ω or 4k7 The fourth and fifth bands are used to determine the percentage tolerance of the resistor Resistor tolerance is a measure of the resistors variation from the specified resistive value and is a consequence of the manufacturing process and is expressed as a percentage of its “nominal” or preferred value Typical resistor tolerances for film resistors range from 1% to 10% while carbon resistors have tolerances up to 20% Resistors with tolerances lower than 2% are called precision resistors with the or lower tolerance resistors being more expensive Most five band resistors are precision resistors with tolerances of either 1% or 2% while most of the four band resistors have tolerances of 5%, 10% and 20% The colour code used to denote the tolerance rating of a resistor is given as: Brown = 1%, Red = 2%, Gold = 5%, Silver = 10 % If resistor has no fourth tolerance band then the default tolerance would be at 20% 103 APPENDIX 4: LIST OF MAGNETIC MATERIALS Types of material Magnetic material Ferrite Ferrite Manganese-zinc ferrite Nickel-zinc
