Film Capacitors

Film capacitors have become increasingly used in a variety of electronic and electrical applications due to their high voltage and temperature ratings, stability, and long life. These characteristics make them an ideal choice for high frequency circuit applications where loads are subject to vibration or vibration extremes. Overall, by design and in comparison to ceramic and paper capacitors, they generally offer more efficient performance.

ECW-H12472HL is a type of film capacitor that is widely used in industrial applications that require a high voltage rating. It is quite robust in terms of its operating temperature range and has a wide capacitance tolerance range as well. The product is also relatively free from physical and performance degradation due to humid conditions or excessive vibration. Furthermore, it has a long life, with up to an MTBF (mean time between failures) of more than 25 years.

Applications

The ECW-H12472HL is widely used in medium and high voltage applications, such as high-power rectifiers, switchgear, power conditioning systems, and motor drives. It is also suitable for applications requiring high dielectric strength, areas with intermittent operations, or a high degree of reliability. In motor drive applications, it is used to increase power quality and efficiency as it is able to smooth power waveforms, absorb high frequency harmonics, and shield electrical equipment from damping.

Working Principle

ECW-H12472HL is a high-voltage film capacitor that incorporates high-grade metallized PAN (polyaniline) film, advanced dielectrics, and a sturdy all-in-one design. PAN film is a polycrystalline film material with superior properties which make it an ideal choice for high-voltage capacitors. Its properties include excellent insulation, stability, and temperature resistance. The PAN film features high dielectric strength, excellent uniformity, low leakage current, and low dissipation factor.

The dielectric system is based on a combination of high-grade and high-ripple-resistant film stacks between two concentric and strong aluminum layers. This construction technique is customized to provide excellent high frequency performance and superior surge current capability. The capacitor has a rugged plastic case, which is designed to meet high humidity requirements and protect the metal parts of the capacitor from mechanical damage.

The capacitor is constructed with a reliable outer shell and is equipped with sufficient safety clearances and creepage distances. This construction design provides protection against external influences, and improves the capacitor\'s performance under extreme environmental conditions. The capacitor also features an advanced self-healing and defect-free feature, which is able to safely isolate short circuits and quickly recovers from shunting or abrupt disconnects.

Overall, ECW-H12472HL is an ideal choice for applications that require a high voltage rating, long life, and efficiency. The device\'s PAN film provides superior film properties and its reliable construction ensures superior high voltage and surge protection even under extreme conditions. Its low leakage current and low dissipation factor allow for optimal power quality, and its self-healing feature provides protection from accidental electrical disruption.
