Film capacitors

Film capacitors (especially polyester film capacitors) offer significant performance advantages over traditional paper capacitors. They are used where stability, high temperature tolerance, good frequency response, low loss, low ESR, long lifetime and higher reliability are required. Film capacitors are used in a wide variety of applications, ranging from simple AC line filtering to DC blocking and power supply bypassing.

B32674E6155K000 application field and working principles

Application Field

B32674E6155K000 is a special polyester film capacitor made by EPCOS designed for DC Link applications. This type of capacitor can be used for a wide range of applications, including power supplies, motor drives, inverters, generators, alternators, and DC voltage boosting circuits.

Capacitor Working Principle

As is common with other capacitors, the B32674E6155K000 works by storing an electric charge across two conducting plates that are separated by an insulating barrier. This charge will then combine with the rest of the circuit to control the current flow.

When a voltage is applied across the B32674E6155K000, an electric current flows into the capacitor and charges the plates. This process creates an electric field inside the capacitor, which makes an electrical connection between the plates, allowing for a current to flow. The electric charge will remain on the plates until the voltage is changed, at which point the plates will discharge the charge until a new voltage is applied.

The B32674E6155K000 is a polyester film capacitor, meaning that the plates are insulated from each other with a layer of polyester film. This type of capacitor is very stable and can withstand high temperatures without degrading. Additionally, it has low ESR, making it well-suited for DC voltage boosting circuits.
