Mica and PTFE capacitors are widely used due to their electrical and thermal characteristics as well as their small size. The MC18FD391J-TF is a mica and PTFE capacitor specifically designed for automotive, medical, and industrial applications. This product is known for its high-temperature stability, excellent endurance, reliable performance, and temperature coefficient of capacitance (TCC) characteristics.
The MC18FD391J-TF is a fixed-value capacitor and operates at temperatures between -55°C and 125°C. It is a multilayer ceramic chip capacitor, consisting of four layers: a base, two electrodes, and two dielectric layers. The two dielectric layers contain mica and PTFE. The high temperature of 125°C enables the MC18FD391J-TF to function properly in most operating environments, including automotive and medical applications.
The working principle of the MC18FD391J-TF is similar to other mica and PTFE capacitors. It stores electrical energy in the form of a capacitor, which acts as a charge reservoir and is capable of holding a large amount of charge and releasing it quickly. In other words, it stores electric charge and can be used to produce a constant current or voltage in a circuit.
The MC18FD391J-TF features a high capacitance tolerance: at temperatures up to 105°C, the capacitance values remain stable and do not deviate from the specified value. Additionally, it has a high dielectric constant, which increases its capacitance value. Its low equivalent series resistance (ESR) ensures its low power loss characteristics and contributes to its high power stability and reliability.
The MC18FD391J-TF also features a low temperature coefficient of capacitance (TCC) which is an indicator of the stability of the capacitor’s capacitance at various temperatures. This feature makes the MC18FD391J-TF ideal for temperature-sensitive applications such as medical equipment and automotive electronics.
The MC18FD391J-TF is known for its excellent long-term stability, being able to work for extended periods of time without compromising performance or reliability. It is also highly resistant to chemicals and resistant to humidity and temperature changes, making it suitable for applications where these variables are critical. Additionally, it has a aesthetically pleasing design, making it a good choice for industrial and medical applications.
Overall, the MC18FD391J-TF is an excellent choice for a variety of applications due to its superior electrical and thermal characteristics, its small size, and its unique temperature coefficient of capacitance (TCC) characteristics. Its durable construction also makes it an ideal choice for long-term applications that require reliable performance and high temperature stability over time.
