貼片電容怎么看參數?這是很多廠家在采購貼片電容的時候需要考慮到的實際問題,畢竟每一家采購商使用貼片電容的工作環境以及電路都有所不同,所以選擇貼片電容之前看好參數才是對工作的負責。
How to see the parameters of chip capacitor? This is a practical problem that many manufacturers need to consider when purchasing chip capacitors. After all, the working environment and circuits of chip capacitors used by each buyer are different. Therefore, it is responsible for the work to be optimistic about the parameters before selecting the chip capacitors.
參數一般指的是貼片電容的尺寸大小、精度、電壓、容量值等。電容的識別可以按這兩種指標:大小(f)、耐壓值(V),具體的參數怎么看紅寶小編為大家詳細講解。
Parameters generally refer to the size, accuracy, voltage and capacity of chip capacitor. Capacitance identification can be based on these two indicators: size (f), withstand voltage value (V), specific parameters how to see, Hongbao small editor for you to explain in detail.
貼片電容:普通型,材質瓷片。外型單一、外觀單一,表面沒有絲印,沒有極性。有多種顏色主要有褐色、灰色、淡紫色等。普通貼片電容的基本單位:pF。
Chip capacitor: common type, porcelain chip material. Single appearance, single appearance, no screen printing on the surface, no polarity. There are a variety of colors, mainly brown, gray, lavender and so on. Basic unit of common chip capacitance: PF.
1、絕緣電阻,用于說明漏電大小的。小容積的電容器,絕緣電阻很大電解電容的絕緣電阻比較小。相比之下,絕緣電阻越大越好,漏電也小。
Insulation resistance, used to indicate the magnitude of leakage. The insulation resistance of capacitor with small volume is large, and the insulation resistance of electrolytic capacitor is relatively small. In contrast, the greater the insulation resistance, the better, and the less leakage.
2、容積與錯漏,實踐性電容量和標稱容量的較大錯漏規模 。
Volume and error leakage, practical capacitance and nominal capacity of larger error leakage scale.
3、附加工作電壓,電力電容器在電源電路中能夠長期穩定、牢固工作,所接納的較大交流電壓,又稱之為耐壓 。
Additional working voltage, the power capacitor in the power supply circuit can work stably and firmly for a long time. The larger AC voltage accepted is also called withstand voltage.
4、溫度系數,在必然溫度規模內,溫度每改變1℃,容量的相對改變值,溫度系數越低越好。
The lower the temperature coefficient is, the better the temperature coefficient is when the temperature is changed by 1 ℃ and the relative change value of capacity is.
5、損耗,在電場的作用下,貼片電容在單位時間內發熱而消耗的能量 。
Loss refers to the energy consumed by the chip capacitor heating in unit time under the action of an electric field.
6、頻率特點,貼片電容的電主要參數隨電場頻率而轉變的特性 。
Frequency characteristics, the main electrical parameters of SMC change with the frequency of electric field.
