RoHS-Compliant Series of High Voltage Stacked SMPS Capacitors

RoHS-Compliant Series of High Voltage Stacked SMPS Capacitors

AVX Corp. has introduced a RoHS-compliant series of high voltage, DIP-leaded stacked SMPS capacitors. Rated for 1,000 - 5,000 V and capacitance values spanning 100 pF to 15 µF, the RV Series capacitors feature low ESR and ESL, low DC leakage current, high current handling capabilities, excellent high frequency performance, and exceptional capacitance retention with frequency. Available in three dielectrics (C0G, N1500, and X7R) and six case sizes with five maximum height dimensions spanning 0.120 in. to 0.650 in., the RV Series is ideal for use in a broad range of high voltage applications, including: medical spectrometry and imaging equipment, semiconductor test equipment, power conversion and conditioning, motors and motor drives, high voltage SMPS, and both commercial and industrial detection, scanning, and quality analysis equipment.

In addition to the aforementioned applications, RV Series stacked SMPS capacitors are well suited for use on the AC input lines of AC/DC converters in the power supplies of spectrometers and ultrasound, CT, and MRI equipment, as well as on the high voltage signal amplifiers between the transmitters and the analog to digital converter transducers in that same equipment. They are similarly well suited for use in commercial and industrial air, food, and water quality analysis equipment, radiation detectors, and the types of baggage- and body-scanning equipment employed by the US Department of Homeland Security. Further, the versatile, RoHS compliant RV Series can also be used as I/O filtering and bulk storage capacitors in high voltage SMPS, as DC blocking capacitors, as DC link capacitors in AC/AC and DC/AC motor drive inverters, as power conditioning capacitors in DC/DC and AC/DC converters, and as start-and-run capacitors in AC induction motors.

C0G RV Series capacitors feature a capacitance range spanning 100pF to 1.2µF, and are available with capacitance tolerances of ±5%, ±10%, or ±20%. N1500 RV Series capacitors feature a capacitance range spanning 100 pF to 1.9 µF, and are also available with capacitance tolerances of ±5%, ±10%, or ±20%. X7R RV Series capacitors feature a capacitance range spanning 100 pF to 15 µF, and are available with capacitance tolerances of ±10%, ±20%, or +80%, -20%. Operating temperatures for the series span -55 °C to +125 °C regardless of dielectric.
