A discharge resistor may be either switched across the. Safe discharging of capacitors in TVs and video monitors It is essential - for your safety and to prevent damage to the device under test as well as your test equipment - that large or high voltage capacitors be fully discharged before measurements are made, soldering is attempted, or the circuitry is touched in any way. That' ll give you around 5 Minutes discharge if anything goes wrong with the switched bleeder. I have seen that later this concept is applied to slow the rate of discharge, but is a resistor actually required, or will the capacitor discharge just fine without one? Additional caution is advised when working with > 50 volt capacitors. This online calculator computes various parameters for discharging the capacitor with the resistor.

Active Capacitor Discharge Circuit Considerations for FPGAs Ian Milne, MOSFET Specialist December The multiple power rails of today’ s FPGAs and high‐ performance processors must be powered up and powered down in strict sequence. Converter output as near as possible to this), implementing a 344KHz first order low pass filter; after this there is a very simple second order passive LRC low pass filter, which has scarcely any effect on the whole audio band, including its top end, but cuts rather drastically any frequency higher than a few hundred kHz, followed by a coupling capacitor to tear away the DC component ( about 2. Now, the resistor value we calculated above was 48 Ω, which isn’ t one of our common values.
