There are many reasons that affect the life of aluminum electrolytic capacitors. Overvoltage, reverse voltage, high temperature, rapid charge and discharge, etc. Under normal use, the biggest impact is temperature, because the higher the temperature, the faster the evaporation loss of the electrolyte. It should be noted that the temperature here does not refer to the [...]
The film capacitor has many excellent characteristics, so it is a capacitor with excellent performance. The characteristics of film capacitors are mainly as follows: non-polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and small dielectric loss. Based on the above advantages, film capacitors are widely used in analog circuits. Especially in the part where [...]
The CBB capacitor is a metallized polypropylene film series structure type, which can resist high voltage and large current impact, has small loss, excellent electrical performance, high reliability and self-healing performance. Features of CBB capacitor:No polarity, high insulation resistance, excellent frequency characteristics, and low dielectric loss;High dielectric constant, small size, large capacity and good stability;Small dielectric [...]
Polyester film capacitor have excellent mechanical properties, electrical properties, and optical properties, so they have a wide range of applications, such as photo negatives, magnetic tapes, video tapes, microfilms, packaging films, and capacitors. In addition to photo negatives, the rest need to add anti-sticking agent main feature 1. Metallized polyester film capacitor, non-inductive winding structure. 2. [...]
If you want to understand the role of capacitors in power supplies, you must understand the type of capacitors, equivalent parameters, the role of capacitors in power supply design and the role of decoupling capacitors in integrated circuit power. 1. Types of capacitors Three commonly used capacitors: aluminum electrolytic capacitors, ceramic capacitors and tantalum capacitors. Aluminum [...]
