Fungsi Kapasitor pada PCB

Fungsi Kapasitor pada PCB

Kapasiti adalah komponen elektronik yang menahan dan melepaskan cas elektrik. Prinsip asas kapasitansi ialah pengisian dan pemakaian,

Sudah tentu, terdapat fungsi membetulkan, berayun dan lain-lain. Di samping itu, struktur kapasitor sangat sederhana, terutamanya terdiri daripada dua elektrod positif dan negatif dan

Medium penebat yang diapit di tengahnya disusun, jadi jenis kapasitansi terutama ditentukan oleh elektrod dan medium penebat. Terdapat banyak penggunaan kapasitor, terutamanya seperti berikut:

1. DC isolation: the function is to prevent DC from passing and let AC pass.

2. Bypass (decoupling): provide low impedance path for some components in parallel in AC circuit.

3. Coupling: as the connection between two circuits, it allows the AC signal to pass through and transmit to the next circuit

4. Filtering: This is very important for DIY. The capacitance on the graphics card is basically this function.

5. Temperature compensation: compensate for the influence of other components on the inadaptability of temperature, so as to improve the stability of the circuit.

6. Timing: the capacitor and resistor are used together to determine the time constant of the circuit.

7. Tuning: systematically tune frequency related circuits, such as mobile phones, radios, and televisions.

8. Rectification: turn on or off half closed conductor switch element at predetermined time.

9. Energy storage: storage of electric energy for release when necessary. For example, camera flash, heating equipment and so on. (today, the energy storage level of some capacitors is close to that of lithium batteries, and the power stored by a capacitor can be used by a mobile phone for one day.

Kapasiti adalah komponen yang diperlukan dalam reka bentuk papan, dan kualitinya telah menjadi aspek yang sangat penting bagi kita untuk menilai kualiti papan.
