Domino Capacitor Color Code Calculator

Comprehensive Guide to Domino Capacitors

Domino capacitors are historic mica and ceramic electronic components that use standardized color-coding systems to signify capacitance values, operational voltage ratings, and performance tolerances. Accurately deciphering these color bands is crucial for electronics repair, vintage radio restoration, and circuit prototyping.

Formula Used

The standard formula to compute capacitance in picofarads ($pF$) from the color bands is defined as:

$$C = (D_1 \times 10 + D_2) \times M$$

Where $D_1$ represents the first significant digit, $D_2$ denotes the second significant digit, and $M$ stands for the decimal multiplier factor corresponding to the designated color code.

How to Use This Calculator

• Select your capacitor standard type from the primary dropdown menu.
• Choose the correct color matching the first and second significant figure bands.
• Pick the appropriate multiplier and tolerance color values from the selector options.
• Click the calculate action button to instantly view precise output measurements.
