We are committed to offering our clients a wide range of Metalized Capacitors, which is highly appreciated for international quality standards. These Metallized Capacitors are available with different values of general and value ratings and are used in the designing of various circuits of electronic and electric appliances.
This product is widely used for DC pulsation, pulse, and AC voltage reduction in instruments, meters, TV sets, and household electrical appliances. It is especially suitable for various types of energy-saving lamps and electronic rectifiers.
We are looking for bulk inquiries for Metallized Polypropylene Capacitors, Metallized Polypropylene Film Capacitors, MPP Series coating capacitors, etc.

Electrolytic caps can be replaced with polypropylene or other film capacitors to improve sound quality. The problem is that, despite having the same value, the film capacitor it replaces is much larger.
the capacitor withstands 1 000 000 hours of operation at 70 °C, indicating that an increase in voltage at lower working temperatures is conceivable without compromising life expectancy and that under these circumstances the lifetime will be restricted to 10 000 hours.
Polypropylene capacitors are perfect for situations where a consistent level of capacitance is required since they display very minimal capacitance variation with time and voltage applied. The temperature coefficient is discovered to be small, negative, and almost linear.
In most cases, polymer capacitors can be used as direct replacements for electrolytic capacitors, as long as the maximum rated voltage is not exceeded.
