6.1.2: Capacitance and Capacitors

While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor. For smaller capacitors a numeric code is used that echoes the color code. Typically it consists of a three digit number such as "152". The first two digits are the precision portion and the third digit is the power of ten multiplier.
