Featuring high dielectric constant (K), the SMM series capacitors provide an extended range of capacitance values in a small case size, freeing up valuable board space. Ideal 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.
Attached to the lead frame with high-temperature solder, Super X7R SMM stacked MLC capacitors have no risk of solder reflow during assembly to the board. Additionally, a Hi-Rel screening option, per MIL-PRF-49470 (B-Level reliability), is available.
