Kyoto, Japan Kyocera Corp. has introduced the KVA16 quad EMI filter array with electrostatic discharge (ESD) protection in a 1608-type package, measuring 1.6 x 0.8 x 0.5 mm. Kyocera said it is the industry's smallest LC filter, approximately half the size of the company's existing KVA21 series of EMI filters with ESD protection.
Like the KVA21 series, the KVA16 series features varistor material developed by AVX, Kyocera's affiliate in the United States. The circuits and structure with the new material were designed with an advanced electromagnetic field simulator developed by Kyocera, optimizing the layout of the inductors and capacitors on the filter array. The result is an 8-kV ESD contact discharge compliant with IEC/EN 61000-4-2.
Even with the added function of ESD protection, the series minimizes insertion loss. It achieves a steep attenuation curve equivalent to the conventional products (the KNA series) over the 800-MHz to 2.0-GHz range and the filter circuit offers attenuation characteristics over 20 dB. The series is RoHS compliant.
Availability: Samples are available. Volume production (10 million units/month) is scheduled for March 2008.
