Film Capacitors

Film capacitors are polarized capacitors that are mainly used to filter, bypass, store and capacitor-coupling next-to-ground and high-frequency applications. They are also used to reduce electrical noise levels, EMI / RFI in digital circuits and as AC line filtering and signal smoothing elements. Generally, this type of capacitor uses a thin plastic polyester or polypropylene film as insulation. Film capacitors are perfect for applications that require specific qualities like high voltage, low loss and stable in-circuit performance.

MKP383312100JFI2B0

MKP383312100JFI2B0 is a series of film capacitor that utilizes two stiff, high temperature polyethylene-naphthalate (PEN) dielectric layers. It performs well in extreme temperature environments, from -40⁰C to 90⁰C. There is a wide selection of casing sizes, such as 0805, 1206, 1808, 1812, 1825 and 2010, and material compositions, including aluminum, silicon, stainless steel and also ceramic. This type of capacitor can withstand a voltage of up to 50V DC and 1.2uF in capacitance.

Application Field

MKP383312100JFI2B0 film capacitors are used when greater stability and reliability are required in extreme temperatures, as this type of capacitor offers a wide range of voltage ratings. These capacitors are typically found in fields such as power supplies, RF circuitry, telecommunication, automotive and also digital ICs. These capacitors are used in grounding, suppressing and bypassing electric noise and improving the EMI suppression capability of circuits.

Working Principle

The basic functioning of this capacitor is similar to other capacitor designs, as it includes two conductive plates and an insulator (the dielectric) in between; the material and layering of the dielectric material being the key difference of this type of capacitor. Cells are connected in series to increase the voltage rating. Electrodes serve as connection to allow current flow and to complete an electrical circuit.
