Film Capacitors are some of the most powerful and versatile electrical components available. The 947D381K132BLMSN, for example, is a low-profile, surface-mount capacitive device that is capable of handling a wide range of applications, from blocking voltage and power supply filtering to power supply decoupling. Its low profile design allows it to be used in a variety of applications, owing to its small size and convenience.

Construction

The 947D381K132BLMSN is built of an 0.74 mm Kapton film with a 9.47 mm diameter. It combines two Kapton foil layers which are epoxy-encapsulated in black resin and pressed together with a force of 500 grams. Its capacitance value ranges from 8.2 to 33 nF, making it ideal for low voltage power supplies and other applications. The package size - 13.2 mm (L) x 9.6 mm (W) x 4.5 mm (H) - allows for high performance in a small package.

Working Principle

Film capacitors are based on the principles of electrostatics, which states that opposite charges attract and like charges repel. When a voltage is applied across a film capacitor it creates an electric field in the insulating material (typically Kapton or other polymers) between the two electrodes. This electric field stores energy in the form of electric potential. The amount of electric potential stored depends on the capacitor\'s capacitance value. When the voltage is removed, the electric field voltage remains and the capacitor acts as an energy storage device.

Application Fields

Film capacitors can be incorporated into a wide range of applications. The 947D381K132BLMSN is no Different. In particular, it can be used in low voltage power supplies, AC line voltage filtering, power supply decoupling, RF blocking, signal processing, and low frequency EMI filtering. Its small size and capacitance value make it ideal for these applications.

The 947D381K132BLMSN is an excellent choice for use in low voltage power supplies. It is able to store and release energy back into the system as necessary, making it an ideal solution for power supply filtering and decoupling. In addition, its small size allows it to fit into tight spaces, making it perfect for densely packed boards. Furthermore, its Kapton design is highly resistant to temperature and other environmental conditions, making it an excellent choice for use in extreme operating conditions.
