Mica and PTFE capacitors are widely used in many applications due to their superior characteristics and performance. The MC12FA470J is a type of mica-and-PTFE capacitor from Alps Electric Co., Ltd., a manufacturer of electronic components. It is a high-frequency ceramic capacitor with a characteristic impedance of 200 ohms and a breakdown voltage of 480V, making it suitable for use in power systems.

The MC12FA470J is best suited for applications such as high frequency power supplies, inverters, converters, and other power systems. It features a wide operating temperature range of -55 to +125 degrees Celsius and is UL approved, which is a major benefit for customers who require high-quality components. In addition, it features a self-healing property which helps to protect the capacitor from shorts, making it ideal for many diverse applications.

The start of working principle is based on the basic electron physics. In mica-and-PTFE capacitors, an electric field is generated between two plates that are separated by a dielectric material. The dielectric material allows the electric field to pass through it without affecting the signal path. The strength of this electric field is determined by the capacitance of the capacitor. The capacitance of the MC12FA470J is 470pF, which is relatively low, and therefore allows the capacitor to be used in higher frequency applications.

When the capacitor is subjected to an alternating current voltage, the electric field between the two plates causes the dielectric material to vibrate, causing a charge to flow and creating a potential difference between the plates. The potential difference then impedes the flow of the current, creating a voltage drop between the two plates. This voltage drop is what creates the capacitive effect of the capacitor.

The MC12FA470J also features an internal current shunting mechanism, which helps to reduce the voltage drop across the capacitor even further. The current opening and closing of the shunting mechanism means that the capacitor is constantly self-adjusting to keep the voltage drop at an optimal level. This ensures that the capacitor has a consistent level of performance, no matter what the application.

The MC12FA470J offers many benefits to customers looking for reliable, high performance capacitors. It offers a wide operating temperature range, self-healing properties, and UL approval, making it ideal for many different applications. The low capacitance and versatile shunting mechanism also make it suitable for use in systems that require high frequency and performance.
