Film capacitors are in widespread use across a variety of electronic and electrical applications, such as resonance circuits, DC-DC converters, SMPS, defibrillators, and more. The 930C1W3P9K-F film capacitor is a product from respected component manufacturer Cornell Dubilier. Its advanced technology and unique features offer a number of performance, reliability, and safety benefits.

Design

The 930C1W3P9K-F film capacitor is an aluminum electrolytic capacitor in a 6.3 mm x 11 mm tall cylindrical package. The device features an epoxy-coated body for protection against environmental damage and is constructed with a variety of process safeguards for optimal performance. The capacitor is rated between -40°C and 105°C and has a ripple current rating of 30 Amps. Its non-inductive design helps reduce the risk of the capacitor interfering with other devices in close proximity.

Applications

High-reliability applications often call for a better performing capacitor than the axial-leaded aluminum electrolytic capacitor. The 930C1W3P9K-F film capacitor excels in these demanding applications with its high performance and increased reliability. Due to its low impedance, it can be used in the following applications:

• DC-DC converters
• Switched-mode power supplies
• Motor drives
• Power supplies
• Lighting ballasts
• UPS
• Medical device applications
• Welding equipment
• Defibrillator
• MRI machines
• Resonant circuits

Working Principle

The 930C1W3P9K-F film capacitor works on the principle of electrochemical double layer capacitor (EDLC). EDLCs are made up of two vastly different plates: a conductor and an ion exchange membrane. The two plates are separated by a porous separator, which contains a highly concentrated electrolytic solution. When voltage is applied, an electric double layer is created at both plates, resulting in an increase in capacitance. The small size of the EDLCs allows for a very high capacitance level.

The 930C1W3P9K-F film capacitor uses this principle to provide optimal performance and reliability. The high-strength electrolyte saturates the porous separator to produce a very high capacitance. The conduction layer also maximizes impregnation of the atoms in the electrolyte and improves the reliability of the device. This results in a high-performance, high-reliability capacitor for use in demanding applications.

Conclusion

The 930C1W3P9K-F film capacitor is a compact device designed for high-reliability applications. Its high capacitance and low impedance make it ideal for DC-DC converters, Switched-mode power supplies, motor drives, welding equipment, lighting ballasts, and resonance circuits. The device works on the electrochemical double layer capacitor (EDLC) principle, which allows for a very high capacitance. Its non-inductive design helps reduce the risk of the capacitor interfering with other devices in close proximity. This makes it an ideal component for a variety of applications.
