AVX Corporation has introduced a new RoHS-compliant series of high-voltage, DIP-leaded stacked SMPS capacitors. Rated for 1,000-5,000V and capacitance values spanning 100pF to 15µF, the new 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″ to 0.650″, 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.

“Many stacked SMPS capacitors for high-voltage applications aren’t RoHS compliant, which limits the applications that they can be designed into. Our new RV Series stacked SMPS capacitors, which are both RoHS-compliant and designed for use in the 1,000- to 5,000-volt range, satisfy this gap in the marketplace and significantly expand the number and types of applications for which they’re an ideal solution,” said Nic Billig, product manager at AVX.

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