ECQ-E12104KFB Datasheet/PDFFilm capacitors are components used in many applications across a range of industries. These capacitors are produced using polymer film technology, with a dielectric medium between two conductive surfaces. The ECQ-E12104KFB is an example of a film capacitor.
Configuration
The ECQ-E12104KFB is a polyester-film capacitor with a radial leaded, metalized-film configuration and a 10% tolerance level. The maximum operating temperature of the capacitor is 125°C, while its rated voltage is 250VAC. It uses a self-healing mechanism, which eliminates the potential for dangerous short-circuits. It also has superior protection from surge currents.
Uses and Applications
The ECQ-E12104KFB capacitor is ideal for use in a wide range of applications due to its reliable and durable construction. These include insertion into power supplies, signal circuits, low-pass or high-pass filters, and RFI suppression. It is also used in wide-range applications, such as high-frequency oscillators, signal transistor amplifiers, capacitors in series, and pulse generators.
Working Principle
Film capacitors are able to store electrical charge, using two layers of conducting material separated by an insulative dielectric. When a voltage is applied to the conductor, a positive charge accumulates on one conductor and a negative charge on the other. This creates an electric field between the two conductors, allowing capacitance.
The ECQ-E12104KFB capacitor is designed to be especially durable. It is constructed with a self-healing mechanism that immediately restores the capacitor to its unbroken state whenever a shortcut occurs between the two plates. This ensures a long-term stable performance.
Conclusion
The ECQ-E12104KFB is a high-quality polyester-film capacitor, designed to offer reliable, long-term performance in a variety of applications. It has a 10% tolerance level, with a rated voltage of 250VAC and a maximum operating temperature rating of 125°C. Its superior surge protection, self-healing mechanism, and wide application scope make it an ideal choice for many electrical and electronic projects.
