Film capacitors are among the most reliable and robust capacitors available in the market. The 154PHB850K2H is a film capacitor manufactured by CapXon, a specialist in high-performance capacitors. It is a high-performance, low-voltage, bipolar capacitor designed for a wide range of applications. 

The 154PHB850K2H features an operating voltage of between 10 and 325 volts, making it suitable for a wide range of uses. It is designed for applications where stability of electrical parameters is a must, such as in control, motor control, HVAC, power supplies, and DC-DC converters. The capacitor has a very low impedance and low ESR (equivalent series resistance), making it suitable for frequency-dependent applications. It also has a high temperature rating of up to +125 °C, making it suitable for high-temperature applications.

In terms of construction, the 154PHB850K2H is made up of a film dielectric, a metalized layer, an end termination, and an epoxy layer. The film is an oxide of titanium, with a very high dielectric constant. It is designed for high breakdown voltage, low dissipative losses at high frequencies and excellent mechanical strength. The metalized layer is made up of copper, which serves as a resistor, and is connected to the end-terminals through plated-through holes. The end-termination is made up of a tin-plated copper plate, which ensures a good reliable connection with the customer’s PCB (printed circuit board). The copper plate is covered with an epoxy layer to ensure environmental protection and to provide good thermal and electrical insulation.

The 154PHB850K2H works on the principle of electrostatic capacitance. This simply means that when a voltage is applied across the terminals of the capacitor, electrostatic fields are created around the film. These fields cause the electric charges to be stored on the plates. The stored charge provides the capacitance, which is the ability to store a large amount of energy for a short period of time.

Due to its high performance and reliability, the 154PHB850K2H is an excellent choice for a wide range of applications, including motor control, HVAC, power supplies, and DC-DC converters. Its high temperature rating, low impedance, and low ESR make it ideal for high frequency and high temperature applications. What’s more, its construction ensures good thermal and electrical insulation, as well as environmental protection.
