WEET WFA CL21 Dip Coated MKT Metallized Polyester Film Capacitor is a common electronic component, which features a wide capacitance range, small size, low loss, high insulation resistance, and good temperature stability.

Compared with other types of capacitors (such as ceramic capacitors, electrolytic capacitors, polypropylene film capacitors, etc.), metallized polyester film capacitors have unique performance advantages, which are specifically reflected in the following aspects:

1.Strong self-healing ability and high reliability

This is one of the most prominent advantages of metallized polyester film capacitors.

2.Non-polar with a wide range of applications

Metallized polyester film capacitors are non-polar, whereas electrolytic capacitors (aluminum electrolytic and tantalum electrolytic) have distinct polarities.

3.Low loss and good high-frequency performance

The dielectric loss of metallized polyester film is low, resulting in little energy loss in medium and high-frequency circuits.

4.Good temperature stability

The temperature coefficient of polyester film is relatively stable. In contrast, some ceramic capacitors have poor temperature stability, with their capacitance changing by up to ±80% with temperature.
