Calculate either the charge, capacitance or voltage across a capacitor using Q=CV.
The hammer in any electrical engineers toolbox. Calculate voltage, resistance and current using Ohm's law.
Resistor dividers are a simple, widely-used circuit primitive for reducing a voltage based on a fixed ratio.
Find the closest E-series (e.g. E12, E96) resistor (preferred value) to your desired resistance.
Find the right size wire gauge for a particular current and voltage drop.
The low-pass RC filter is probably the simplist and most used electronic filter. Great for input signal filtering.
Calculate the resistor and capacitors values for a 555 timer in astable configuration.
A calculator for working out the impedance of a standard microstrip style track.
PCB track current carrying capability calculator, using the IPC-2152 standard.
PCB track current carrying capability calculator, using the IPC-2221a standard.
PCB via current carrying capability calculator, using the IPC-2221A standard.
Calculator the thermal resistance of a via.
Calculate the dew point using the Magnus equation.
Calculate the temperature, resistance (reference or actual), or beta-coefficient of NTC thermistors.
This calculator can be used to calculate the values of the critical component values for a buck converter.
Rotate objects in 3D using angle-axis, rotation matrices, euler angles or quaternions.
Calculate CRC values from either a large number of popular CRC algorithms or define one yourself.
