The B32529D0225K189 is a film capacitor, and it is a dedicated product developed by EPCOS AG, a subsidiary of TDK.Film capacitors, also known as dielectric capacitors, are an important component in many electronic circuits. They are used to store energy, provide gating and filtering of signals, and reduce harmonic distortion. The B32529D0225K189 is constructed from B-class Polyester/Polypropylene film as the dielectric, ensuring a long lifetime, low ESR and high reliability. This film capacitor has a capacitance of 0.225μF, which is suitable for wide range of applications such as switching power supplies, low voltage oscillators and resonators, AC/DC-adapters and saw filters.The device consists of an insulated metal foil electrode which is bonded with a corona-resistant epoxy resin. The lamellae are glued to each other with a high-temperature-resistant adhesive heated in a furnace. This process produces a self-healing effect, and in the event of a breakdown, the voltage will be conducted through the neighboring lamellae and the capacitor will, therefore, not fail completely.The B32529D0225K189 also has a relatively high rated voltage of 250 V AC and can withstand peak operating voltages of up to 1500 V AC and 5500 V DC with a 10/1000 operating voltage. A life expectancy of up to 5000 hours is also guaranteed with temperatures ranging between -25 and +70 °C.Furthermore, it has excellent electrical characteristics, making it suitable for use in a variety of applications. It has a capacitance tolerance of ± 5%, and an insulation resistance of up to 10000 Megohms. It also has a very low electrical leakage current of less than 0.1μA.The working principle of the B32529D0225K189 is based on the effect of two electrodes in an electrical field. When a voltage is applied across the two electrodes, an electric field is generated, which creates an opposing electrical charge. This opposes the current flow and creates a voltage drop, which is equal to the applied voltage, but in opposite polarity. This effect is known as capacitance and is used in a variety of applications, such as filters, timing circuits, signal coupling and signal gating.The B32529D0225K189 is an ideal choice for applications that require high reliability and long life. Its high capacitance and high rated voltage make it suitable for a wide range of applications. In addition, its excellent electrical characteristics ensure that it performs reliably even in the most demanding conditions.
