Internationally Recognized Capacitors operate up to 125°C.

Press Release Summary:

Comprised of encapsulated radial through-hole ceramic safety disc capacitors, 900 Series is designed for interference-suppression AC line filtering applications. Safety certified capacitors are classified as either X and/or Y capacitors, respectively suited for primary use in line-to-line (across-the-line) and line-to-ground (line by-pass) applications. Depending on model, products are certified to withstand impulses up to 4, 5, or 8 KV.

KEMET Launches New Line of Industrial Grade Safety Disc Capacitors

900 Series Internationally Recognized Capacitors Offer Reliable Operation up to 125 Degrees Celsius

GREENVILLE, S.C. -- KEMET Corporation (NYSE: KEM), a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, today announced the release of the new Radial Through Hole Ceramic Safety Disc Capacitors.

"KEMET's 900 Series encapsulated radial through-hole ceramic disc capacitors are specifically designed for interference-suppression AC line filtering applications. Having internationally recognized safety certifications, these capacitors are well-suited for applications that require keeping potentially disruptive or damaging line transients and EMI out of susceptible equipment," said Dr. John Bultitude, KEMET Technical Fellow. "They are also an ideal solution for suppressing line disturbances in motors, relays and switching power supplies," continued Dr. Bultitude.

Safety Certified capacitors are classified as either X and/or Y capacitors. Class X capacitors are primarily used in line-to-line (across-the-line) applications. In this application there is no danger of electric shock to humans should the capacitor fail, but could result in a risk of fire. The class Y capacitor is primarily used in line-to-ground (line by-pass) applications. In this application, failure of the capacitor could lead to danger of electric shock.

Typical markets include alternative energy, industrial/lighting, medical, and telecommunications. The Safety Disc capacitors complement KEMET's ERO610, ERK610, ERP610, KJY, KJN series, and FILM EMI suppression capacitors.
