Film Capacitors

The BFC236958472 is a type of thin film capacitor, which is made using monolithically deposited metal-oxide films over ceramic substrates, and is primarily used in military and aerospace applications, as well as in ultra-high frequency communications. The capacitor enables a very small form factor, along with a stable high-frequency performance.

Application Field

The BFC236958472 capacitor is suited for applications that require high temperature resistance as well as higher frequency performance, such as those found in aerospace and military applications. It is also used in UHF transceivers and other RF devices, and has a variety of additional applications in the medical industry.

Working Principle

Thin film capacitors are technically non-polarized capacitors, which means they are fabricated like a diode using a thin film as the insulating layer between two electrodes. The two electrodes are then connected to a conducting substrate layer, creating an electric field between them. When an AC or DC voltage is applied, the electric field creates a capacitive current across the dielectric layer, creating an electrical charge between the two electrodes. The increase in charge is proportional to the applied voltage, and when the voltage is removed, the charge dissipates as the electric field between them collapses.

In the case of the BFC236958472, this field is highly stable, and can be used to filter signals in the high frequency range. This capacitor is also highly reliable in temperature extremes, and is capable of operation in environments ranging from -30°C to +150°C.

Conclusion

The BFC236958472 capacitor is a reliable and stable solution for applications that require high temperature resistance and/or high frequency performance. In aerospace and military applications, this capacitor can provide dependable performance and an overall small form factor. It is also well-suited for medical applications, RF devices and UHF transceivers, and can provide high-frequency signal filtering in these applications.
