Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a type of capacitor that is made from organic polymers often used for blocking oscillations, filtering and coupling signals. The F339X141548MIP2T0 is one such type of film capacitor, widely used for its unique combination of low ESR, low ESL, and excellent vibration and shock resistance.

Application Field

The F339X141548MIP2T0 film capacitor is widely used in communication, medical, and military electronic devices. The F339X141548MIP2T0 offers reliable performance and low ESR in automatic test equipment, radios, navigation instruments, and other portable consumer electronics.

The F339X141548MIP2T0 is also used in medical applications such as ventilators and wearable pulse oximeters. Its strong vibration and shock resistance make it a great choice for electrocardiograph electrodes and pacemakers.

In the military, the F339X141548MIP2T0 is often used for radar systems and in flight simulators. Its unique combination of low ESR and low internal storage capacity favors high-frequency operation and low power consumption in radar systems.

Working Principle

The F339X141548MIP2T0 consists of two metalized polycarbonate films, with a special insulating coating between them. The special coating is able to withstand high temperatures and will not crack, shrink, or delaminate when exposed to environmental extremes. In combination with the metalized films, this allows the F339X141548MIP2T0 to conform to lead spacing requirements and ensure long-term reliability.

When a voltage is applied to the F339X141548MIP2T0, electrical current flows through the capacitive circuit. The current causes the films to vibrate inversely, which generates an electrical field between the films. The electric field acts to store the energy for later use.The F339X141548MIP2T0 also exhibits excellent temperature performance, offering superior stability over a wide temperature range of -55 to +125 degrees Celsius.

The F339X141548MIP2T0 is a great choice for challenging applications due to its low ESR, low ESL, and excellent vibration and shock resistance. As a film capacitor, it offers superior performance and long-term reliability when compared to other types of capacitors. It is ideal for medical, military, and communication applications.
