High-voltage MLCs aim for commercial success
A new commercial-grade high-voltage ceramic surface mount capacitor product line is designed for applications demanding reliability at high voltages.
More options for ceramic capacitors
Kemet is continuing to broaden and enhance its ceramic portfolio with the introduction of several new ceramic surface mount offerings.
The standard termination for all surface mount tantalum-MnO2 and organic polymer KO-CAP products will be changed from tin-lead to 100% matte tin.
Military T492 and COTS T493 products will not be affected.
Lead-free ceramic leaded conformally coated radial (Golden Max) product is available now.
Ceramic leaded conformally coated axial (Aximax) product with lead-free terminations will be available in June 2004.
Lead-free versions of the remaining ceramic through-hole and all tantalum through-hole devices are scheduled for 2005.
Ceramic MLCCs, aluminium polymer AO-CAP part types, and the KO-CAP T525 series are already available with lead-free terminations.
"Kemet's introduction of lead-free standard terminations reiterates our commitment to be 'easy-to-buy-from' while providing the highest degrees of quality, delivery and service", said Dr Jeffrey A Graves, Kemet's Chief Executive Officer.
"By eliminating lead from these product lines, we are not only supporting our customers' requirements but we are also making a conscious effort to comply with relevant environmental regulations".
Products with the 100% matte tin termination finish solder properly in eutectic tin-lead and lead-free processes and are both backward and forward compatible.
It is confirmed that tin whiskering is not a performance issue with this product through JEITA/NEMI recommended test conditions.
The industry's lead-free initiative is being driven by environmental legislation, such as the End-of-Life Vehicle (ELV), Restriction on Hazardous Substances (RoHS), and Waste Electrical and Electronic Equipment (WEEE) directives.
Kemet will maintain limited availability of products with tin-lead terminations sufficient for customers requiring a lead-bearing termination for use in military or other high-reliability applications.
