See the typical range: higher-to-lower ratio is 1 million in all three cases

Some cases capacitor has polarity

In future, add other variations of symbols

- 7. Passive Electronic Components ©Monzur Kabir of 157 Resistor Code SIL (Single In-Line) network: • The 4 and 7 are significant digits and the 3 is the decade, giving 47 x 1000 or 47 KΩ • The letter after the numbers is the tolerance. The different representations are: M=±20%, K=±10%, J=±5%, G=±2%, F=±1%. • Detail Spec: http://www.vishay.com/docs/31509/csc.pdf SMD (Surface Mount Device): • The 1 and 0 are significant digits and the 3 is the decade, giving 10 x 1000 or 10 KΩ Ref: http://www.lalena.com/audio/electronics/color/ Direct Value: • Resistors with larger physical size are often printed the value directly on their body
- 8. Passive Electronic Components ©Monzur Kabir of 158 Standard Resistor Values Electronic Industries Association (EIA) standard E24: Standard E24 specifies resistors based on 5% tolerance (often resistor of this category has 2% tolerance now a days due to advancement of manufacturing techniques) 100 110 120 130 150 160 180 200 220 240 270 300 330 360 390 430 470 510 560 620 680 750 820 910 Standard Resistor values = × 10M Ohms (Where M can be any integer, positive or negative) For other standards: http://www.logwell.com/tech/components/resistor_values.html
