bypass condenser
Học thuậtThân thiện
Definition
Noun: A bypass condenser is a capacitor designed to provide a low-impedance path for alternating current (AC) signals, particularly high-frequency ones, while blocking direct current (DC). It is used to shunt or "bypass" unwanted AC signals (like noise or ripple) away from a specific part of a circuit, typically to ground.
Usage
The term is used in electronics and electrical engineering to describe a specific component's function within a circuit. * It is often placed in parallel with a device or power supply line. * Its purpose is to filter out high-frequency interference.

Advanced Usage
- Decoupling Capacitor: In modern terminology, a bypass condenser is commonly called a decoupling capacitor. Its role is to decouple one part of a circuit from another, preventing energy from one part from affecting the other.
- For optimal performance, each logic chip should have a bypass condenser (decoupling capacitor) between its VCC and ground pins.
Variants and Related Words
- Bypass Capacitor: A more modern and general synonym for "bypass condenser." The term "condenser" is an older term for capacitor.
- Decoupling Capacitor: A functionally identical component, emphasizing its role in isolating circuit segments.
- Shunt Capacitor: Describes the same action of providing an alternative, low-impedance path.
