Film Capacitors

Film capacitors are a type of capacitor that are manufactured from plastic films, such as polyester, polypropylene, and polycarbonate. These capacitors are typically small, lightweight, and low cost. They also generally have a large capacitance and can handle higher voltages than comparable ceramic capacitors. Film capacitors are used in a variety of applications, ranging from consumer electronics to automotive and industrial applications.

890334027030CS application field and working principle

The 890334027030CS film capacitor is a surface-mount chip capacitor that is designed for use in applications such as automotive, industrial and consumer electronics. It has a capacitance of 190uF and a voltage rating of 32VDC. The capacitor’s Unique Dielectric Property (UDP) allows for a wide temperature range of -30 to 125°C.

Film capacitors are polarized, meaning that they must be properly connected to ensure that the correct electrical polarity is present. The 890334027030CS capacitor incorporates a “X” polarized marking, which indicates that the capacitor must be connected to the positive voltage first, followed by the negative voltage.

The 890334027030CS film capacitor uses a polyethylene-terephthalate (PET) film as its dielectric and electrodes made of aluminum. This combination gives the capacitor a high dielectric strength, low ESR, and good moisture resistance. The capacitor also features an optimized electrode structure which reduces the self-inductance and improves its performance.

The 890334027030CS is commonly used in power supplies, motor controllers, inverters, and DC-DC converters. It is also used in automotive applications such as ignition systems, fuel pumps, and accessory power circuits. Due to its low cost and high capacitance, it is also used in consumer electronics such as DVD players and audio equipment.

Conclusion

The 890334027030CS film capacitor is a versatile, low cost, and high capacitance capacitor that is well-suited for use in a wide variety of applications. Its wide temperature range and low ESR make it an ideal choice for automotive, industrial and consumer electronics applications.
