Film capacitors assist energy conversion while providing low losses, high-efficiency and long life. One of the main manufactures or suppliers of film capacitor is Electronic Concepts. They offer prototype and custom manufacturing, as well as a diverse spectrum of standard product lines ranging from small chip size capacitors to large building blocks. Since June of 1969, Electronic Concepts has been able to grow as one of the most recognized and respected name in the electronic component industry. They focus on specialty polycarbonate film capacitors. Film capacitors are made out of two pieces of plastic film covered with metallic electrodes that wound into a cylindrical shaped winding, with terminals attached, and then encapsulated.
In general, film capacitors are not polarized, so the two terminals are interchangeable. What has helped Electronic Concepts grow in the last couple of years is their ability to address the changing needs of the industry. They are known for their many patent and innovative products. These products include type ECR capacitor, which is physically the smallest film capacitor in the industry. Electronic concepts are also known for their type HECR capacitor. This type of capacitor is a hermetically sealed version of the type ECR; however the HECR is more suitable for more stringent applications. Both the ECR and HECR capacitor are qualified to the military’s specifications. The last two capacitors Electronic Concepts are known for is the type 5MC capacitor and the type MP80/MP88 capacitor. The type 5MC capacitor is directly addressed for the requirements of the swift mode power supply industry. The MP80/MP88 is snubber capacitors that especially designed for protecting IGBT’s used in inverters and charges in electric vehicles.
In today’s industry film capacitors are widely used in power applications including but not limited to DC Link, DC output filtering and as IGBT snubbers. Capacitors are also used for oscillators and resonant circuits. They are also used for electronic filter applications that are high quality factor. These applications include high pass filters, low pass filters and band pass filters. Films capacitors can also be used for tuning circuits for audio crossovers in loud speakers, in hold A/D converters and in peak voltage detectors. When it comes to Capacitors it is important to recognize what part family they belong in. The part families a capacitor can fall into are ceramic, film, plastic or electrolytic.
Many capacitors may have exactly the same capacitance value but they could have different voltage ratings. Capacitors come defined with a series of characteristics. These characteristics include nominal capacitance, which is measured in pico-Farads, nano-Farads and is marked onto the body of the capacitor as numbers, letters or colored bands. The second characteristic is working voltage, which is the maximum continuous voltage either DC or AC that can be applied to the capacitor without failure during its working life. Another characteristic is tolerance, which is expressed as a plus or minus value. Leakage current, which is another characteristic, is a result of electrons physically making their way through the dielectric medium, around its edges or across its leads and which will over time fully discharging the capacitor if the supply voltage is removed. Film capacitor is a part that is in high demand in the electronic industry that is used for many day-to-day parts.
