See SI Units or Metric Units to read more about these. R, C and L values are given these prefixes.
We have resistors like 10 Tera Ohms of Glass Surface Resistance to 1 Micro Ohms of a Small Copper Wire Resistance.
1 Pico Farad of Capacitance of two Large PCB Tracks in a Multi Layer PCB to 10 Milli Farad of a Huge Electrolytic Power Supply Filter.
Then Lastly 10 Nano Henrys Inductance of the Twisted Connector Cables in a Computer and 1 Henry of a Powerful Choke that can kickback 10 Kilo Volts when a 10 Amps current thru it is broken.
|milli||1 / 1000||1.e-3|
|micro||1 / 1000,000||1.e-6|
|nano||1 / 1000,000,000||1.e-9|
|pico||1 / 1000,000,000,000||1.e-12|
Electronic Tables and Charts
Electronics is Fun, is it Not.
Just Google 0.1% or 1000/1e6 or 1000/1000000 ....answer in the calculator that pops up is same. Read "Parts Per Million - PPM" as used in Resistors. 1000 ppm is 0.1%.
Most MFR Resistors have a Temperature Coefficient of 100 ppm/°C. Read more at Resistance - Ask The Applications Engineer. 100ppm is like 0.01%.
0.01% is close to the resolution of a 4-1/2 Digit Voltmeter. 100.00 is the reading you will see for 100 Volts. Imagine the front end attenuator in that voltmeter is Standard MFR and a "Hot" Voltage Regulator is leaning on it, (you wanted to make your pcb compact) The last digit will be Spinning like a Ferris Wheel. Are we understanding Instrumentation!
