Application for calculating color codes for 3, 4, 5, 6-strips resistors. It is lite version of
Electronic Component Codes app.
The Application checks the entered value against E-series E6, E12, E24, E48, E96, E192, depending on the accuracy.
Resistor color coding can contain 3, 4, 5 and 6 stripes.
The first strip is usually placed closest to the edge of the resistor. For example, on 4-band resistors, the gold or silver tolerance band will always be the last.
These resistors have two bands for the resistance value and one multiplier. Such resistors have a tolerance of 20% and a range of values corresponds to E6 series.
Four-band color code is the most common option. These resistors have two resistance bands, one multiplier and one tolerance band. These resistors have a tolerance of 5% or 10%.
This is a group of high precision resistors. They have an additional stripe to indicate the third significant digit. Therefore, the first three bars represent significant digits, the fourth bar represents the multiplier, and the fifth bar represents the percentage tolerance.
This group has tolerances of 2%, 1%, 0.5% and less.
- Tolerance of 2% corresponds to E48 series;
- Tolerance of 1% corresponds to E96 series;
- Tolerance of 0.5% and less corresponds to E192 series;
6-band resistors are usually designed for high-precision resistors with a specific temperature coefficient (TCR). The temperature coefficient of resistance characterises the dependence of electrical resistance on temperature. The initial temperature is considered to be + 25°C. Temperature coefficient is measured in ppm/K.
Single black stripe or zero resistance resistor
A resistor with one black stripe is called a zero resistance resistor. It is mainly used as a jumper with the function of connecting conductors on a PCB. The advantage of using a resistor pack is that you can use the same machines to place components on a PCB.
Application also contains help and detailed description for all codes of electronic components and lists of standard values for E series.
Currently, this application is translated into 6 languages, but new languages will be added in future versions.
Light/Dark theme support
Depending on the user’s preferences, the application can be displayed in light or dark theme. The application has 3 options:
When you set the systems default option, the application will use the selected theme on the device.
When you set the systems default option, the application will use the theme installed on the device. The other options set a theme independent of the system theme. Dark theme can also be installed on older versions of Android that do not have theme switching.
