Low profile DC/DC power supplies boast ceramic capacitors

Wed, 11/07/2012 - 10:51am

Aimtec has launched three new series of DC/DC converters featuring multilayer ceramic capacitors (MLCCs). According to the company, MLCCs used in the AMxQ-Z family of DC/DC converters withstand high temperatures; higher voltage conditions and reduced leakage current better than traditional tantalum capacitors. Ceramic capacitors can also withstand the high reflow temperatures associated with the lead free soldering as required for RoHS compliance. In addition to being non-polarized, the use of  MLCCs in Aimtec’s AMxQ-Z power supplies is said to provide suppressed power line noise, reduced harmonics from ripple currents, lower resistance and inductance, which helps to prevent the device and the circuit from overheating.  The family boasts a low profile of 7mm (including stand offs), for applications in which component height is critical. Available in 2-W, 3-W and 6-W power ranges, the AMxQ-Z series feature wide (2:1) input ranges of 4.5-9, 9-18, 18-36 and 36-75 VDC, stepping down to tightly related (±1 percent) single and dual outputs of ±12 and ±15 VDC at efficiency rates as high as 88 percent.
