Exxelia landed on the far side of the moon with its PM948S film capacitors on board the Chang’e 4 spacecraft.
PM948S are polyester PET capacitors dedicated to H.F. switch mode power supplies in various high reliability applications. Polyester has a high dielectric constant and high dielectric strengh, enabling miniaturization while providing excellent self-healing properties. Exxelia has more than 20 years of heritage in the design of metallized polyester capacitors for aviation, defense and space.
