Film capacitors are an incredibly diverse and versatile type of capacitor. They are a highly efficient, low cost and reliable capacitor family that can be found in a wide range of applications. One of the most popular in the film capacitor family is the PVC12268.

The PVC12268 is a film capacitor specifically designed for DC blocking, DC coupling and AC line bypass applications. It is a foil-polypropylene dielectric-foil capacitor, encased in a black injection molded PVC housing. The wide temperature range of -40˚C to +85˚C, means that these capacitors can handle quite extreme conditions, making them ideal for use in harsh industrial, automotive, and military environments.

In DC blocking applications, such as line filtering, the PVC12268 will block low frequencies while allowing higher frequencies to pass through. This is achieved through the capacitor\'s high voltage rating combined with its high capacitance value. The capacitor achieves such a high capacitance due to the dielectric difference between the two layers of metallized polypropylene film which allow for a larger charge to be stored and discharged reliably and quickly. Additionally, the capacitor\'s low equivalent series resistance (ESR) allows for stable operation even under high temperature fluctuations.

The PVC12268 is also a popular choice for DC coupling applications, such as coupling between stages of an amplifier. In DC coupling applications, the PVC12268 can be used to create a smooth transition between the stages while at the same time providing some protection from power supply transients. The capacitor\'s high capacitance value allows a high amount of power to be stored and discharged quickly, allowing for a smoothing effect. The capacitor\'s low ESR ensures that the current is not lost as heat and is instead stored in the capacitor.

The PVC12268 can also be used in AC line-bypass applications. Specifically, the capacitor is used to bypass noise and power supply spikes on AC power lines. The high capacitance value and low ESR create a low impedance path when the capacitor is connected in parallel with the AC power line. This prevents power surges and other noise from traveling through the power line and instead short-circuits to ground, preventing any disturbances.

Overall, the PVC12268 is a high-performance film capacitor that can be used for a variety of applications. It is a reliable and cost-effective solution for DC blocking, DC coupling, and AC line bypass applications. The capacitor\'s wide temperature range makes it ideal for use in harsh environments, and the capacitor\'s low impedance and high capacitance values ensure high performance over a wide range of frequencies. As such, the PVC12268 should be considered for any application requiring a reliable and efficient film capacitor.
