With the development of technology, the scope of application of electronic components can be described as a wide range. In addition to our common film capacitors used in audio, in fact, polyester capacitors will also be used. Recently, Xiaobian saw a problem with a green 2A104J in the sound. Is this

The schematic diagram of the power amplifier input capacitor is written on a polyester capacitor. Can it be replaced by a ceramic capacitor? Yes, but with high voltage resistance, the high frequency performance of high voltage ceramic capacitors is better than polyester capacitors. No matter what ca

With the development of technology, the application range of capacitors has gradually expanded. Some people ask why the energy-saving lamps use polyester capacitors instead of other capacitors. When the polyester capacitor in the energy-saving lamp is how to choose good or bad, let the editor solve

Everyone knows that the replacement of capacitors is not arbitrary. It should be safe to use in the guidance of professional technicians or in the manufacturer's instructions. Someone asked if the polyester capacitor damage in the desk lamp can be replaced with an electrolytic capacitor. The answer

In the process of receiving customers, sometimes the editor will receive many questions from customers, then the text for everyone to sort out some common problems with polyester capacitors, I hope to help everyone! 1) What is the replacement for the polyester capacitor 2A224J if the same capacitor

Polyester capacitor refers to a metal foil film made of a prime, rolled into a cylindrical or flat cylindrical core, the medium is polyester, polyester film capacitor. The ceramic capacitor is extruded from a high dielectric constant capacitor ceramic barium titanate titanate into a circular tube, a

Polyester capacitors are used in a wide range of applications. Polyester capacitors are often used in a variety of DC or mid-low frequency pulsating circuits, especially when manufacturers prefer to use them as bypass capacitors. Because polyester capacitor is a capacitor with high molecular weight

Theoretically (ie, assuming that the capacitor is a pure capacitor), the larger the capacitor, the smaller the impedance and the higher the frequency of the pass. However, in practice, capacitances in excess of 1 μF are mostly electrolytic capacitors and have a large inductance component. Therefore,

1. Advantages: Accuracy, loss angle, insulation resistance, temperature characteristics, reliability and environment adaptability of the film capacitors are better than electrolytic capacitors and ceramic capacitors. The 2. Disadvantages: The capacitance and price ratio of polyester capacitors and t
