Why Bypass Capacitor is essential in Electronic Circuits?
A bypass capacitor is placed between VCC and GND close to the IC power pins.
Its primary role is to eliminate high frequency noise and fluctuations from the supply line.
During sudden current demand by the IC the capacitor delivers instant current.
It ensures voltage stability and shields the circuit from disturbances.
Why is it needed on every PCB?
• Minimizes power supply noise
• Enhances signal stability
• Avoids IC malfunction
• Increases overall PCB reliability
Application
100nF ceramic capacitor positioned near the IC power pin.
