Component Finder Tools

Braking Resistor Calculator

To calculate the right size of the resistor you need the characteristic data of the load cycle: brake time or duty cycle and the total cycle time. Furthermore you need the brake power Pbr and the minimum resistance value Rmin which is defined by the VFD.


Discharge Resistor Calculator

Resistors are an important part of capacitor charge and discharge circuits. At the start of an application where the capacitor has to be charged and a voltage is applied across a capacitor, initially it appears like a short circuit.
