Mica and PTFE capacitors are broadly used in a variety of devices, including telecommunications and computers. The MCH38FM120J-Y is a mica and PTFE capacitor with a range of useful features. It’s unique composition makes it ideal for applications demanding both high volumetric efficiency and high temperature resistivity. In terms of it’s application field, the MCH38FM120J-Y is primarily used in medium to high power Electronic Equipment (EEE), such as Telecommunications and Computing. It has a working temperature range of -40C to +105C and due to it’s high thermal conductivity, its noise level is decreased. Furthermore, the capacitor yields high volumetric efficiency, given its compact design and relatively high capacitance values. The capacitance values of the MCH38FM120J-Y range from 1nF up to 3.3nF (and higher), with 50V, 100V, 200V, 300V and 600V versions available. It also features a low equivalent series resistance (ESR) of 0.3 ohms, which is an important factor when it comes to avoiding unnecessary losses. The high temperature stability of the MCH38FM120J-Y ensures that the capacity fluctuation is well below 0.5pF/°C, making in suitable for high switching frequency applications. In terms of its construction, the MCH38FM120J-Y consists of two micaceous ceramic plates with a film of PTFE between them, allowing a potential to be applied across the plates. The micaceous ceramic plates form a dielectric, which acts as an electrical capacitor, storing energy. The capacitor has an insulation resistance of more than 10GΩ, meaning it is able to store a high amount of energy while still providing the required insulation. The MCH38FM120J-Y is ideal for applications involving relatively high switching frequencies. It has a reactance of up to 0.25ohm min with a 0.8ohm 0.2s cutoff response, making it a reliable choice for applications requiring quick switching. Furthermore, it is more reliable than conventional capacitors due to its higher circuit temperature and this makes it an obvious choice for applications with high requirements for high temperature performance. Finally, the MCH38FM120J-Y capacitor can also be used in power applications due to its high current capacity, making it an ideal choice for devices that require both high temperatures and high switching frequencies. In conclusion, the MCH38FM120J-Y capacitor is a reliable and efficient choice for applications needing high temperature performance and high switching frequencies. It is, however, important to note that due to its high temperature stability, it is suitable only for medium to high power applications.
