The chip Y capacitor is a small capacitor. It plays a vital role in the circuit principle. By adjusting the capacitance value, the frequency response, phase response and matching resistance of the circuit can be adjusted. The chip Y capacitor has many specifications. We know that the chip Y capacitor has many parameters. Among them, the most basic parameters include capacitance value, tolerance, rated voltage, capacitance series, etc.
1. Capacitance value

The capacitance value is one of the most basic parameters of the chip Y capacitor, generally expressed in microfarads (μF), picofarads (pF) or nanofarads (nF). It refers to the charge that the capacitor can store, that is, the size of the capacitor. When choosing, the size of the capacitance value needs to be determined according to the needs of the circuit principle. Generally speaking, the larger the capacitance value, the greater the stored charge, but the price will also increase.

2. Tolerance
Tolerance refers to the error range between the capacitance value of the capacitor and the rated value. It is generally expressed as a percentage and is divided into positive and negative tolerances. The lower the tolerance, the better the electrical performance of the product. Common tolerances are ±1%, ±2%, ±5%, etc.
3. Rated voltage
The rated voltage refers to the maximum voltage that the capacitor can withstand. Generally speaking, the higher the rated voltage, the better the quality, reliability and performance parameters of the capacitor. Therefore, when selecting, the rated voltage of the patch Y capacitor should be determined according to the maximum voltage value of the circuit operation.
