Metallized Polypropylene

Film Capacitors

F862 Series for Harsh Environmental Conditions

Class X2, 310 VAC

Applications

Across-the-line EMI filtering and connection in series with the mains

for high stability grade applications in severe ambient conditions:

• Capacitive power supplies

• Energy meters

• DC applications

• Industrial

• Automotive

Overview

X2 rated capacitors such as the F862 Series are required to achieve a stable performance during

operational life while meeting safety requirements. The metallized film dielectric is a key factor

with regards to the safety aspect. For example, the polypropylene dielectric provides excellent

self-healing characteristics. However, improvements were necessary to maintain stability in high

temperature and high humidity environments. KEMET recognized this challenges and researched

materials that would produce more robust parts for extreme applications. As a result, improvements

to all of the major capacitor components have been implemented, including the metallization layer,

the film used as the dielectric, the resin which fills the package, and the box (or case). With these

changes, the F862 offers very high capacitance stability while still meeting ENEC, CUL and CQC

international safety requirements.
