EMI Filter with ESD Protection
Kyocera introduced the KVA16 quad EMI filter array, LC distributed constant type component featuring both electromagnetic interference (EMI) filtering and electrostatic discharge (ESD) protection in a single package. The unit, the so-called 1608 type since it measures 1.6 x 0.8 x 0.5 mm (typ.), is a LC filter, approximately half the size compared to the KVA21 series (2012 type). The circuits and structure with the new material were designed with advanced electromagnetic field simulator developed by Kyocera Corporation, optimizing the layout of the L (inductors) and C (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 realizes steep attenuation curve equivalent to the conventional products (the KNA series) over the 800-MHz to 2.0-GHz range and the filter circuit that shows high attenuation characteristics over 20 dB. The KVA16’s optimized monolithic LC filter also offers higher reliability, which is suitable for volume production, and complies with the RoHS directive.
