Capacitance color code table.
Capacitor color code table. The number of dots or bands on a capacitor may vary from one another. The capacitors which are shown in the above figure are metalized polyester capacitors with color codes. Generally color codes are indicated using dots or bands.
Learn deeply about capacitor chart. Surface mount ceramic capacitor. Capacitor color codes for identification chart.
For example the digits 471 4710 470pf. Most capacitors actually have the numeric values stamped on them however some are color coded as resistors are. Additional bands have meanings which may vary from one type to another.
Displayed capacitor chart with tantalum capacitor color codes capacitor code guide mica capacitor values etc. Capacitor tolerance letter codes table. Capacitors may be marked with 4 or more colored bands or dots.
The value is represented on the capacitor by using capacitor color code or directly. A three letter code consists of the two value digits and a multiplier much like the resistor colour codes in the resistors section. All the above capacitors have different capacitance and tolerance valuesthese values can be understood by the color code table which.
The capacitors first and second bands are the significant number bands the third is the multiplier followed by the percentage tolerance band and the voltage. Below two tables shows the values of colors given on the capacitors. The colors encode the first and second most significant digits of the value and the third color the decimal multiplier in picofarads.
In this each color represents a specific parameter for capacitance values tolerance and working voltages. The voltage maximum up to which the capacitor can withstand before dielectric breakdown is called as working voltage of the capacitor and capacitor voltage color code is represented in below table. You may wish to check out our resistor color code table and calculator.
For mica capacitors color coding is shown in dots while for tubular capacitors it may be shown using bands. The color code for this capacitor is written on the body as capacitance value and the voltage. This capacitors have low esr values when compared with other group of capacitors.
