AVX Corporation has expanded its range of surface mount switch mode power supply (SMPS) capacitors to include the new SMM Series (switch mode max capacitance) stacked MLC capacitors, which incorporate the “High K” Super X7R dielectric. Featuring high dielectric constant (K), the capacitors provide an extended range of capacitance values in a small case size, freeing up valuable board space. Applications for the new series range from high-power DC/DC converters to general power supplies, and also include telecom networks, snubbers, aerospace instrumentation panels, and hybrid power supplies, among several others. AVX’s new Super X7R SMM stacked MLC capacitors feature a voltage range of 50 V to 500 V, a capacitance range of 0.56 µF to 120 µF, and an operating temperature range of -55°C to +125°C. Available in SMM3, SMM4, and SMM5 styles, the series also offers various lead options that provide effective mechanical decoupling of the ceramic capacitors from the board, minimizing stresses during board flexing, vibration, or temperature cycling.
