Film capacitors are electronic components that have significant roles in electrical and electronics engineering. They store energy by storing electrical charge in the dielectric layers of a dielectric material, such as polyester, polycarbonate, polypropylene, and metal films. Film capacitors typically come in surface-mount, through-hole, and radial-leaded packaging formats. Additionally, depending on the application, film capacitors may also be constructed differently, allowing for a wide range of applications.

224MSR102K is a non-inductive polyester film capacitor product, manufactured by Cornell Dubilier. Its primary application is in power conditioning circuits in switch mode power supplies, and in other high frequency, power factor correction and EMI filters. 224MSR102K film capacitors are non-inductive, self-healing, and 30-40% lower loss than most conventional ceramic capacitors. They offer high-stability and ripple-current ratings, as well as superior temperature characteristics.

Now, let’s talk about the working principle of 224MSR102K film capacitors. In general, film capacitors are composed of two conductors with two terminals, separately isolated by an insulating dielectric material. When a potential is applied to the positive and negative terminals of a film capacitor, an accumulation of electric charge forms on the conductors, which in turn creates capacitor. The dielectric material is then polarized by the electric field, and it stores the electrical charge. The stored energy is then released back to the circuit when the applied potential decreases. This process is repeated many times during the capacitor’s operation, and is known as capacitive charging and discharging.

Using Cornell Dubilier’s 224MSR102K film Caps, in particular, they feature the use of polyester dielectric material which is excellent for high-dissipation, small temperature coefficients, and low dielectric absorption. It is able to provide very low loss and better ripple current decisions. They also allow for a greater operating range of temperature, up to 85°C. Moreover, 224MSR102K capacitors also operate with a wide frequency range, from less than 1Hz up to several hundred kHz.

In conclusion, 224MSR102K is a reliable and efficient film capacitor ideal for use in high frequency, power factor correction and EMI filter circuits. Its use of polyester dielectric material supports a wide frequency range, high temperature operation, and high ripple current capability. In addition, due to its self-healing property, it is able to absorb voltage impulses or spikes for extremely long service life.
