Alpha and Omega Semiconductor recently released three new multi-line RC EMI filters. The AOZ8040, AOZ8043, and AOZ8045 provide integrated EMI and RF filtering solutions for high-speed wireless data applications, such as smart phones, 3G-enabled notebook PCs and eBook readers. The AOZ804x product family includes devices with 8, 6, and 4 channels of EMI filtering. Leveraging AOS’ advanced [TVS]2 TM technology (Transient Voltage Suppression utilizing Trench Vertical Structures), the products include integrated ESD diodes rated at ±20kV, far exceeding the IEC61000-4-2 specification of ±8kV contact and ±15kV air. The new products provide optimized filter attenuation performance of -20dB at 1GHz and a high cut-off frequency of 250MHz, offering a low capacitance of 9pF typical to allow faster data speeds while preserving signal integrity.See a datasheet for the AOZ8040.
