Film Capacitors

Film capacitors are widely used in a variety of electronics applications and have become increasingly popular as they offer a wide range of benefits for electronic circuit design. One such type of capacitor, the Type 405PHB250K2H, is particularly well-known in the field of electronic design.

The Type 405PHB250K2H film capacitor is a non-polarized polyester film capacitor. It has a wide temperature range from -55°C to +125°C, and features excellent insulation characteristics and a long life even at high temperatures. This capacitor is ideal for use in customer electronic applications such as instruments, automotive electronics, consumer electronics, and telecommunications, to name a few.

In terms of its application field, these capacitors can be employed in circuits found in power supplies, frequency converters, AC line filtering, grounding systems, voltage snubbing, and current limiting. The Type 405PHB250K2H film capacitor is known to deliver a broad range of capacitance value, ranging from 0.1 mF to 220 mF, in voltage ratings from 6.3V to 1600V. With its high capacitance range, this capacitor has the capability to meet the most rigorous filtering requirements.

In terms of its working principle, this particular capacitor functions by utilizing two layers of polyester film with carbon or tantalum oxide deposited on both outer surfaces. These layers form a dielectric sandwich that allows an electric field to be formed between the two-sized conductive plates. As the electric field forms, an imbalance of the electrical charges takes place between the two layers. This, in turn, creates a storage of energy, which is released in the form of a capacitance value.

The Type 405PHB250K2H capacitor is also known for its excellent linearity, high impulse voltage resistance, and low temperature factor. These traits make it an ideal solution for many high-power switching circuits and other electrical applications.

Overall, the Type 405PHB250K2H film capacitor is a superb choice for a wide range of electronic applications. Its capability to deliver a wide range of capacitance values and excellent temperature and DC leakage characteristics make it suitable for a variety of electronic projects. Furthermore, the excellent linearity, high impulse voltage resistance, and low temperature factor of this capacitor are instrumental in its ability to deliver reliable performance within an application.
