The self-healing capability of KEMET's film capacitors makes them a great choice for safety across power lines.

For harsh environments

KEMET's new Y2/X1 film capacitors of the R41-T series offer the best conditions for use in harsh environmental conditions due to their operating temperature range of -40°C to 125°C and the THB Class IIIB test (85°C, 85% relative humidity (RH), 1,000 hours at 300VAC/1,500VDC). AECQ-200 certified versions are also available. R41T is constructed of metallized polypropylene film encapsulated with self-extinguishing resin, in a box of material meeting the requirements of UL 94 V–0.

KEMET’s safety certified film capacitors are specifically designed for conducted emissions attenuation in AC line filtering applications. The self-healing capability of film capacitors makes them a great choice for safety across power lines as well as 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.
