Vishay’s New Four- and Eight-Channel LC EMI/ESD Filter Arrays Offer Input Loss <1 db in Ultra-Compact LLP1713 and LLP3313 Leadless Packages With Low 0.6-mm Profile
MALVERN, Pa. — May 8, 2009 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of two new four-and eight-channel LC EMI/ESD filter arrays with input loss of < 1 dB in ultra-compact LLP1713 and LLP3313 leadless packages.
With a low profile of 0.6 mm, the new VEMI filter arrays are designed to save board space and provide EMI filtration and ESD protection for embedded cameras and LCDs in portable gaming systems, PDAs, mobile phones, and any other system designed to receive RF signals in the 800-MHz to 2400-MHz frequency range. The low-pass filter in the VEMI arrays allows low-frequency signals to pass through with very low attenuation, while high-frequency signals, such as the carrier frequency of mobile communications systems, are shorted to ground.
The new filters include the four-channel VEMI45LA-HNH in the LLP1713 package, and the eight-channel VEMI85LA-HGK in the LLP3313 package. Delivering high-quality filtering, the new devices feature typical cut-off frequencies of 150 MHz, a low line resistance of 12Ω, and line inductance of 10 nH. Low leakage current helps to prolong battery life.
The VEMI45LA-HNH and VEMI85LA-HGK provide transient protection for data lines as per IEC 61000 4 2 (ESD) at ± 25 kV (air and contact discharge) and IEC 61000 4 5 (lightning) from 4 A (tp = 8/20μs). The lead (Pb)-free filters are compliant with RoHS 2002/95/EC and WEEE 2002/96/EC and feature a environmentally friendly “green” molding compound.
Samples and production quantities of the new LC EMI/ESD filter arrays are available now, with lead times of 10 weeks for large orders.
