MC18FD271J-TF

Mica and PTFE capacitors, such as the MC18FD271J-TF, are used in a wide variety of applications. They are constructed using two layers of mica insulation and coated with a polymer film, such as PTFE, to provide insulation between them. This combination of materials creates a capacitor with a high breakdown voltage, a low form factor and makes it suitable for use in high voltage power circuits.

Mica and PTFE capacitors are ideal for use in industrial and commercial settings. For example, they can be used to provide protection against short circuits and electrical faults in electrical appliances or to provide smoothing of high frequency signals in mains powered equipment. They are also suited to application in automotive electrical systems, such as air conditioning, audio systems, and for car alarms.

The working principle of Mica and PTFE capacitors relies on the fact that due to the insulation between the mica layers, an electric field is created around the two layers. This electric field attracts and repels particles of opposite charge, creating an electric charge within the capacitor’s layers. When a voltage is applied across the terminals of the capacitor, this electric charge is stored, as an excess of positive or negative ions in the layers. The amount of charge stored is dependant on the amount of voltage applied.

The MC18FD271J-TF is a radial-leaded plastic film capacitor with high-temperature rated insulation materials. It has two outer layers of mica insulation and is plastic-bonded and coated with a layer of PTFE insulation. It has a working voltage of 270 volts DC VDC and its maximum allowed DC working voltage is 315 volts. The capacitance range for this device is 0.01 to 10 μF ±10% and its tolerance in all capacitance ranges is ±5%. Its durability is rated up to 2000 hours at 85°C and an insulation resistance of at least 1000MΩ at 20°C.

In addition to industrial and commercial applications, the MC18FD271J-TF is also suited for use in antenna match circuits, RFID tags, high voltage discharge lamps, miniaturized inverters and charger circuits. Its construction, with two outer layers of mica and a layer of PTFE insulation, makes it extremely reliable for use in circuits which require a stable and consistent working voltage level. Its small form factor also makes it a suitable choice for applications where a small size is essential.

The MC18FD271J-TF is a robust and reliable capacitor that is suitable for a wide range of industrial and commercial applications. Its two outer layers of mica insulation and the layer of PTFE insulation provide a high breakdown voltage and a low form factor, making it suitable for use in high voltage power circuits. Its small form factor also makes it a great choice for applications where size is a major consideration.
