Key Points
• Pre-charging resistors are a core component
in circuits containing large capacitive loads,
as sudden spikes of current can easily
damage system components, connectors,
wires, and even PCB traces, while discharging
resistors help to quickly dissipate large
voltages that can remain across capacitor
terminals after power is removed
• The nature of sudden current spikes and large
discharging currents means that pre and
discharging resistors need to be carefully
selected so that they can handle the extreme
voltage and current spikes that occur with
large capacitive and inductive loads
• Bourns has developed a multitude of solutions
for engineers who need to deploy pre and
discharge resistors, with varying surge, heat
dissipation, and package options
