Film Capacitors

Film capacitors (or film dielectric capacitors) are electrical passive components used for their properties of electrical insulation and relatively high power density. The term "film" in their name originates in their structure, which consists of a thin film substrate patterned with a thin sputter anode conductive metal material that forms a capacitor dielectric element. The film is in turn covered by another thin film patterned with a thin sputter cathode metal material, forming the environment for the dielectric element.

MKP1845347106 Application Field and Working Principle

The film capacitor with the part number MKP1845347106 is a miniaturized, radial-leaded, polypropylene film capacitor that is designed for applications such as power amplifiers, audio filter networks, speakers, audio frequency circuits, audio amplifiers, and automotive audio systems. The capacitor has a maximum operating temperature range of -55 deg C to +105 deg C with a high ripple current capacity and low equivalent series resistance (ESR) value.

This type of capacitor is a non-polarized capacitor that uses two metallic films separated by a dielectric that store electric charge and creates a capacitance. It consists of two electrodes where one is the anode (positive) and the other is the cathode (negative) charged to a certain voltage. When a voltage is applied to the MKP1845347106 film capacitor, an electric field is generated as electrons attract each other. The dielectric between the two electrodes causes the electric field to weaken, thus forming a capacitance.

The MKP1845347106 film capacitor is equipped with a wide range of features, including a polypropylene film dielectric, low impedance, low ESR and power, fast charge and discharge time, and a long life span. It also includes high reliability and low self-inductance characteristics, making it ideal for use in sensitive electronics circuits.

The capacitor is a non-polarized type and is not affected by the polarity of the applied voltage or current. The MKP1845347106 has a rated voltage of 450 VAC, a capacitance of 4 uF, a capacitance tolerance of +/- 10%, a maximum operating frequency of 200 kHz, and a maximum ripple current of 2.2 A over an operating temperature range of -25°C to +70°C.

The MKP1845347106 has an extremely low ESR of just 0.60 Ohm nominally and is capable of operating in a wide range of temperatures and frequency ranges. It also comes with a self-healing characteristic that eliminates the risk of breakdown due to a short circuit. The capacitor also has a high ripple current capacity and a low dielectric absorption.

The MKP1845347106 film capacitor has a variety of applications, ranging from those in sensitive electronics circuits to those in military and aerospace applications. Its low ESR, low inductance, fast charge and discharge characteristics, and excellent ripple current are particularly useful in applications where frequency response, power, and timing are critical.
