While either of the capacitors is charged, the base voltage of the transistor is negative, thus the transistor remains OFF. The frequency of this is related to the time needed for the capacitor to discharge (when it is connected in reverse polarity to ground via a resistor - e.g. C1-R2). LED Flasher circuits usually work on the same principle.
Voltage Rating: If a capacitor cannot handle the voltage applied to it, it may fail prematurely. This is often due to selecting a capacitor with a voltage rating too close to the operating voltage. Current Capacity: Similarly, capacitors have a maximum current capacity. Exceeding this capacity can lead to overheating and failure.
Visual Clues: Physical damage to the capacitor’s casing, such as cracks or splits, is a clear sign of a problem. This can be due to mechanical stress, overheating causing the casing to burst, or manufacturing defects.
There are several potential causes for why your LED light flickers. It may be due to loose or incorrect wiring, incompatible dimmer switches, or faulty bulb components such as a defective LED driver. Here’s a quick rundown of what’s included in this guide to LED light flickering: Dimmer Switch: Why Do My LED Lights Flicker On A Dimmer?
While there may be an easy fix for flickering LED bulbs, there are also times when the issues are more serious. LED bulbs can flicker because there are voltage fluctuations in your wiring or the wiring is loose. When you call Brennan Electric, we’ll help you identify the problem and provide the necessary repairs.
Normally, the top of these capacitors is flat, but as they fail, the top can dome or bulge outward. Causes: This bulging is typically due to gas buildup inside the capacitor. The gas is produced when the electrolyte inside the capacitor begins to break down due to overheating, overvoltage, or age-related wear.
