Film capacitors, also known as plastic film capacitors, are a type of film made up of a dielectric material laminated between electrodes. They are primarily used for filtering, decoupling, buffering, and coupling applications. 461M30692C-189 is a film capacitor designed primarily for controlling AC ripple currents in applications such as uninterruptible power supplies (UPS), motor drives, and power converters. This paper will discuss the application field and working principle of the 461M30692C-189 film capacitor.

Application Field of 461M30692C-189 Film Capacitors

The 461M30692C-189 film capacitor is available in two sizes, 1206 and 20 x 20 mm, which makes it suitable for a wide variety of electrical equipment. The 461M30692C-189 has been designed for use in power line harmonics suppression, EMI/RFI suppression, AC power line decoupling and filtering, and industrial AC inverter/converter applications.

The 461M30692C-189 film capacitor has a wide operating temperature range of -20°C to 105°C. This allows the capacitor to be used in a variety of harsh working environments. The ultracapacitors also have a high capacitance value, which allows them to store more energy per unit volume than traditional aluminum electrolytic capacitors. This high capacitance makes them attractive for use in motor drives, power systems, and inverter/converter systems.

The 461M30692C-189 film capacitor also has a low impedance, meaning that it can provide improved performance in AC power line decoupling and filtering applications. The device also has a high ripple current rating, allowing it to handle large AC peak currents. This makes it suitable for controlling AC ripple currents in applications such as uninterruptible power supplies.

Working Principle of 461M30692C-189 Film Capacitors

The working principle of the 461M30692C-189 film capacitor is based on dielectric absorption. Dielectric absorption is the effect whereby the electrical resistance of a capacitor changes slightly with time under AC voltage. This effect is caused by the dielectric material of the capacitor absorbing a small amount of the applied AC voltage. In other words, the dielectric material of the capacitor can store a small amount of energy and release it when the voltage is turned off.

The 461M30692C-189 film capacitor uses a special type of dielectric material called polypropylene. This material has a high dielectric strength, which allows it to absorb more energy than conventional dielectric materials. The polypropylene dielectric material also has excellent temperature stability, which prevents the capacitance value from changing significantly with time and temperature.

The 461M30692C-189 film capacitor has several other features that make it suitable for controlling AC ripple currents in applications such as uninterruptible power supplies and motor drives. The device has an extremely low equivalent series resistance (ESR), meaning that it can provide improved performance in AC power line decoupling and filtering applications. The device also has a high ripple current rating, allowing it to handle large AC peak currents. This makes it ideal for use in uninterruptible power supplies and motor drives.

In conclusion, the 461M30692C-189 film capacitor is a high-performance device suitable for controlling AC ripple currents in a variety of applications. It has a wide operating temperature range and a high capacitance value, making it suitable for power line harmonics suppression, EMI/RFI suppression, AC power line decoupling and filtering, and industrial AC inverter/converter applications. The device also has an extremely low ESR and a high ripple current rating, making it suitable for controlling AC ripple currents in a variety of applications.
