Vishay Intertechnology, Inc. (NYSE: VSH) recently announced the introduction of a new series of low-impedance, automotive-grade miniature aluminum electrolytic capacitors, the 172 RLX, that offer higher performance and reduced form factor than previous-generation solutions. The BCcomponents 172 RLX series capacitors offer ripple currents up to 4.9 A, can operate at +105 °C, have a lifetime of 10,000 hours, and are available in 14 form factors from 10 mm x 12 mm to 18 mm x 40 mm.
Compared to previous generation solutions, the recently released capacitors are AEC-Q200 compliant, with smaller form factors, lower impedance for a given package and voltage, higher capacity, and 54% higher ripple current for the same rated capacitance-voltage (CV). For example, while the previous generation solution of 1000 mF / 10 V rated CV devices had a ripple current of 1100 mA in a 10 mm x 16 mm package, the 172 RLX series capacitors have a ripple current of 1700 mA in a 10 mm x 12 mm package, allowing designers to use fewer components, increasing design flexibility and saving board space. The 172 RLX series capacitors feature radial-lead, blue sleeve-insulated cylindrical aluminum cases with voltage reduction, voltage ratings up to 50 V, capacities from 150 μF to 15 000 μF, and impedances down to 0.011 W at +20 °C. The capacitors are charge and discharge proof. As polarized aluminum electrolytic capacitors with non-solid electrolytes, these RoHS compliant devices are suitable for smoothing, filtering and buffering of switching power supplies, DC/DC converters, motor drives, and control units in industrial, automotive, communication, audio-video, and electronic data processing (EDP) applications.
