Film Capacitors

Film capacitors, also known as "thick film capacitors" are an integral part of any electronic circuit; they help to stabilise the power supply and reduce noise. Film capacitors are generally made from a material called PET (polyethylene terephthalate), which is like plastic film.

PET film capacitors are commonly used in many different types of electronic circuitry, particularly in three-phase industrial motor drives and inverters due to their low ESR (equivalent series resistance), linear discharge and high isolation. Film capacitors are also widely used in AC motor controllers and in power supplies where high-precision energy storage is required.

Film capacitors offer high insulation resistance, good chemical and temperature stability, and a wide temperature range. They are also available in a range of different sizes and can be adapted to fit most applications.

SFP37T15K238B-F Application Field and Working Principle

SFP37T15K238B-F film capacitors are designed for DC and AC applications and are available in a range of capacitances ranging from 0.1 uF to 15 uF. They have a Frequency Characteristic of 3.5kHz to 1MHz, a Capacitance Tolerance of ±10%, T.E.B.O. of 850V, and Insulation Resistance of 2.5G ohm.

The SFP37T15K238B-F film capacitor works on the principle of voltage breakdown in an oxide film. When a voltage is applied to the capacitor, the voltage is then spread out across the dielectric material, resulting in an increased charge across the capacitor. The increased charge causes the oxide film to break down and the current passes through the capacitor\'s terminals.

The SFP37T15K238B-F film capacitor can be used in many different types of DC and AC circuits, including AC line-monitoring systems, switch-mode power supplies, and general-purpose power supplies. They can also be used for EMI (Electromagnetic Interference) suppression and RF (Radio Frequency) filtering, and for providing protection against high voltage overshoot.

The combination of high insulation resistance, low ESR and DC bias stability makes the SFP37T15K238B-F film capacitor an ideal choice for a wide range of applications. It is the perfect solution for low ESR requirements and for applications where high-precision energy storage is required.
