Film capacitors are a type of capacitor commonly used in high-power applications. Characterized by their low impedance and high voltage rating, these components are popular in power supplies, filters, and regulator circuits. The 475PSB700K2R is a type of film capacitor designed for applications up to 400VDC and has a capacitance range of 0.1 to 2.2 uF. In this article, we will discuss the application field and working principle of the 475PSB700K2R.

The dominant application field for the 475PSB700K2R is in switch mode power supplies, or “SMPS”. SMPS are popular for their high efficiency and light weight. In an SMPS, the 475PSB700K2R capacitor acts as a filter to reduce noise and ripple voltage. It is typically connected between the power supply’s DC output and ground, allowing the output to remain at a steady DC voltage. In addition to its use in SMPS applications, the 475PSB700K2R can also be used to filter the AC frequency of any photovoltaic system, such as a solar energy system.

In terms of its working principle, the 475PSB700K2R is a type of polymer film capacitor. This type of capacitor is constructed from a thin layer of polymer film, which is sandwiched between two metalized plates. The polymer film has an inherent dielectric constant, which is affected by the temperature and applied voltage. This varying dielectric constant is what makes a film capacitor so useful in filtering applications, as it is able to respond quickly to changes in both temperature and voltage.

The 475PSB700K2R has a low VSWR of 0.5%, which is why it is perfect for switch mode power supplies. Its frequency range is from 100kHz to 1GHz, which is ideal for filtering out high-frequency noise. It also has an extremely fast charge/discharge time of just 0.5us, making it perfect for use in bypass circuits. The capacitor has a wide temperature range of -25°C to +85°C, so it can be used in a wide variety of applications.

To put it simply, the 475PSB700K2R is an ideal film capacitor for applications that require low impedance, high voltage ratings, and a wide temperature range. Its high frequency response and fast charge/discharge time make it well suited for SMPS applications, as well as photovoltaic systems. With its excellent performance characteristics, the 475PSB700K2Ris no doubt one of the best film capacitors on the market.
