37FB4425-F

Film capacitors refer to capacitors whose dielectric material is made of a super-thin plastic film which is insulated by metal layers. 37FB4425-F is a radial film capacitor with superior performance. It is an aluminum electrolytic capacitor used for DC blocking, filtering, timing, and AC line bypass in low frequency circuits.

Applications:

• 37FB4425-F is widely used in consumer electronic products, auto audio, LCD driver power and other DC power fields.
• Due to its long life characteristics, and temperature stabilization technologies, it can be used in harsh environmental conditions including high and low temperatures as well as very damp or moist atmospheres.

Working Principle:

Since the 37FB4425-F capacitor uses a unique film material for its dielectric layer, it has excellent insulation performance and low losses. As current moves through the capacitor, the aluminum film is magnetized, converting some of the electrical current to a magnetic field. The magnetic field generates a powerful electrostatic field to keep the 47Formic acid electrolyte stable. As the current continues to flow through the aluminum film, it induces a change in the electrostatic field which causes the molecule of the conductive electrodes to move, producing electrical energy.

The 47Formic acid electrolyte helps to strengthen the capacitor\'s longevity and stability. The aluminum film forms an efficient barrier, which prevents the electrolyte from mixing with the film. As a result, the aluminum film is less susceptible to electrolytic corrosion than standard wet electrolytic capacitors. Moreover, the 47Formic acid electrolyte has high insulation resistance which allows the capacitor to perform at higher switching frequencies.

Conclusion:

The 37FB4425-F film capacitor is ideal for high frequency applications, such as DC blocking, filtering, and timing circuits in consumer electronic products and automobiles. Constant current discharging protection, reverse voltage protection, and operating temperature ranges from -30°C to 85°C, ensures the stability of long-term performance and reliability.
