...system in which one axis is the paper 's brightness from 0 to 100%, another axis is the green/red direction, and the third axis is the blue/yellow direction. Brightness, opacity, and clarity are important considerations. In terms of special features...
Resistors
(779 companies)
The first band (brown) and second band (orange) indicate a number of 13. The third band (red) indicates a multiplier of 102. The fourth band (silver) indicates a +-10% tolerance. Therefore the resistance is: 13 x 102 = 1300 O +-10%. Five band resistors read...
Shrink Wrap and Stretch Films
(523 companies)

Refractometers
(148 companies)
Refractometers measure the critical angle of refraction through a sample. The critical angle of refraction will change with concentration.
Aluminum Electrolytic Capacitors
(210 companies)
Aluminum electrolytic capacitors use an electrolytic process to form the dielectric. Wet electrolytic capacitors have a moist electrolyte. Dry or solid electrolytic capacitors do not.
